jelly ice cream

"His ideal of dessert is a peanut butter and jelly sandwich." She offered that as an explanation right after she said there would be no birthday cake.

"Maybe ice cream and cookies… something we can stick some candles in."

So I set out to make a special birthday dessert for someone who doesn't like cake, but likes peanut butter and jelly sandwiches and, apparently, ice cream and cookies. Easy, I thought, I'll make peanut butter cookies and grape ice cream sandwiches. As luck would have it, I had a concord grape puree in my freezer that would serve as the base for the ice cream. And I had a recipe for killer peanut butter cookies that I had refined over the years and recently tweaked to include miso. But you know what they say about the best laid plans…

Unpacking in the client's kitchen, I had a sudden vision of the grape ice cream… still sitting in my freezer at home! I wanted to panic but there was no time. My schedule was tight even before I was asked to move dinner up a half hour.

As I began preparing dinner, my attention turned to a replacement for the ice cream. With a kitchen full of professional appliances, but no cooks in the house, I knew there was little chance of finding an ice cream maker tucked away in a cupboard. I had plenty of cream, but nothing for a flavor base or sugar. A search through the kitchen produced neither, but I did find three jars of grape jelly. I assessed the situation: no equipment to churn— but I had cream and a sweetened flavor base. A plan was quickly put in place: melt the jelly, blend in the cream, freeze in a shallow tray, whisk often, hope for the best, and pray that I wasn't turning into Sandra Lee. I got the base in the freezer just as the first guests arrived. They were hungry. And impatient. And I had to focus on dinner.

It wasn't until dinner was on the table and I returned to the kitchen that I remembered the neglected ice cream base. I opened the freezer expecting to find a solid block of grape-flavored ice crystals. To my surprise (and relief) it yielded easily to a spoon and out came a scoop of creamy smooth ice cream!

Since then, I've made this ice cream several times with both commercial and homemade jellies. I've tried churning it in an ice cream machine to test the difference. It was slightly creamier, but not dramatically so. I've even kept it uncovered(!) in the freezer for 4 days with no loss of texture or ice crystal build up. I believe this works because jelly is largely invert sugar and pectin, a combination with a high freezing point that stabilizes texture by preventing it from freezing solid and forming ice crystals.

While it may not be the most refined of ice creams, it comes together with only two ingredients and minimal effort. That alone (and that it saved my ass) is worth adding it to my emergency food kit.

Melt the jelly until it is completely fluid. Add the heavy cream, a little at a time, while whisking. Pass through sieve into a bowl or container. Freeze thoroughly.

peanut butter miso cookies

Some time ago, I mentioned adding miso to peanut butter cookies on twitter. I received a number of requests for the recipe/ratios, which I promised to post.

You wouldn't know that it's miso that makes these cookies special unless you were privy, but you'll notice the difference in the rounded flavor. Sweets that are nuanced with savory and salty are always a winning combination in my book.

peanut butter miso cookies

makes 24 7.5cm/3" cookies

106g unsalted butter, at room temperature
130g peanut butter
40g shiro miso (light miso)
88g dark brown sugar (preferably muscavado)
80g granulated sugar
8g glucose
53g egg
5g baking soda
10g boiling water
175g all-purpose flour

Place the butter, peanut butter, miso, brown sugar, granulated sugar, and glucose in a mixer bowl. Beat the ingredients with the paddle attachment at medium speed until light and creamy. Add the egg and beat just until incorporated. In a small bowl, dissolve the baking soda in the boiling water and add to the mixer bowl along with the flour. Mix on low speed for 2 minutes until all of the ingredients are well combined.
Preheat oven to 163C/325F, or 157C/315F if using convection. Using a 3.80cm/1.5" scoop, lay out level scoops of dough on a silpat or parchment-lined baking sheet, leaving about 5cm/2" between cookies to allow for spreading. Chill cookies for 20 minutes to firm dough. Scoops of raw dough can also be frozen for future cookie cravings, then packed into ziplocks. Remove cookies from refrigerator and press with the tines of a fork in a cross-hatch pattern, if desired. Bake for 10 minutes for a softer cookie, or 12 for a crisper cookie.

Miso and peanut butter are so similar in appearance and texture that I'm surprised I haven't made the connection before. In addition to improving a classic cookie, the peanut butter-miso connection captured my imagination for another product: peanut miso.

Most people don't realize that peanuts are in fact legumes. Culinarily, we use them like nuts, but botanically they belong to the plant family Leguminosae, or Fabaceae, and are more closely related to peas and beans. This connection begs the question: if miso is made from soybeans, can it also be made from other beans?

I do know that [I] can't make miso from citrus rinds, though I gave it a good try. During the 10 month fermentation, I had hopes of transforming all sorts of products by fermenting with Aspergillus oryzae(koji mold), the fungus used in the production of miso, soy sauce, and sake. In my haste to make a new product, I failed to follow two fundamental tenets: understanding of product and process, and groundwork. Had I started with a time-honored traditional soybean miso, I would've had a map for when it was on course and where it veered off. Had I done my research, I would have understood that pectin-rich citrus pericarps were not an inviting environment for the enzymatic reaction that koji forms with protein.

Still, I'm hopeful and excited about roasted peanut miso.
And spicy black bean miso.
And fermented hummus.
But first— I'll start with the basics.

earthy potatoes and magic ham

After two years, this blog still challenges me to poke and prod and go places I haven't been before. It reminds me that despite what I think I already know, the only thing I really know is that there is always more to know.

I'm grateful for that.
I wouldn't want it any other way.

I'm also grateful to those of you that take time out of your busy, busy lives to drop me a line. To ask questions. To say hi. To send encouragement. To take me to task. And sometimes, after I respond, you respond back. And so on. And the next thing I know, I have a new friend.

I'm grateful for that, too.

Sometimes, my new friends send me things. Special things. The kind of things you can't buy in a store. Or anywhere else for that matter.
Sometimes, they send me inspiration. Or boxes of sunshine. They even send me magic.

And just in case there was any doubt, it was clearly labeled POP'S MAGIC HAM.

Uwe's pop is a magician. On his farm in Texas he transforms pork loin into something not of this world. Uwe and Chad describe the magic far better than I could. I can tell you, though, that with a smoke whisperer for a father, Uwe has a lot to be grateful for.
And so do I.

If you've ever received food that promises magic, you'll know that the first thing you want to do is eat it. And if it's good, you'll want to eat it all. That's part of the magic.

And if you, like me, showed heroic restraint and stopped yourself short so someone else can enjoy it too, then you know that magic is meant to be shared.

Some time later, you may find yourself with a few handfuls of tiny fingerling potatoes that are intended to share a plate with the magic ham. And you wait patiently to roast them because your oven is currently full of dirt (after all, it's early spring and you need sterile soil to start your seedlings). And as you wait, your nostrils fill will the smell of roasted earth, and you look at the potatoes and slap yourself upside the head (gently, of course) and think DUH. And you grab a trowel and head for the garden and fill a casserole dish with damp earth.

Back in the kitchen you bury the potatoes in the earth and it just feels right. You put them in the oven and set a timer. You hope against hope that they turn out tender and fragrant, but they don't. You look with despair at the shriveled hard pucks and realize that they are victims of the hygroscopic properties of silica. You try again with a fresh batch of potatoes, this time soaking the soil thoroughly, and you smile, remembering how you used to make mud pies as a child and you realize that you've come full circle.

They turn out perfect: soft, tender, earthy by design. You give them a quick rinse in hot water, sad that you had to do so because you like the way they looked with bits of soil clinging to them. Then you remember the crispy cream and crumble some over the hot potatoes with a pinch of salt and a grind of pepper. You toss them and watch the bits of toasted milk solids soften and melt, coating the potatoes with butterfat and you are satisfied.

You arrange the potatoes on a plate and shower them with ultra thin slices of the magic ham (because it came with clear instructions: SLICE ULTRA THIN). You taste and think that the flavors of earth and smoke need something to bounce off of. Something fresh. Something green. You scan the herbs that you have growing on a windowsill and under lights. Thyme (nah)… mexican oregano (maybe)… nutmeg geranium (could be interesting)… oxalis (probably not)… ram rau (definitely not)… tahoon (bingo!). You taste the tahoon, just to be sure. Green. Herbaceous. Sun-warmed earth. Oily beechnuts. Perfect. You pick a handful of leaves and whirl them in a blender with olive oil and a pinch of ground sumac, working quickly before the potatoes cool.

You eat the earthy potatoes and magic ham and come to a sudden realization. It is this:
In your entire life, you've cooked with fire. Sometimes with water. Sometimes with air. And now you can add earth to the list.

Somehow, that makes you feel complete.

artichoke fresh cheese cherry

A plant is a chemical universe unto itself.

Even an innocuous blade of grass produces more natural compounds than we can properly appreciate. Some compounds contribute to the plant's growth and development. Some combine to attract pollinators and seed dispersers. And yet others exist to deter predators and pathogens. These complex systems of chemicals all work together to help the plant achieve one thing: survival.

The artichoke doesn't need to rely on its chemical arsenal for protection from predators; nature has bestowed it with cellulosic armor and barbs for that purpose. But even those haven't deterred the indomitable human curiosity and our insatiable appetite once we discovered that beyond its armament, there is something good to eat inside. Our attraction to the artichoke's buried heart is a chemical one; phenolic, to be precise.

Plant chemistry, simplified
All living organisms produce compounds that are essential to life. In plants, these can be divided into two metabolic groups:

Primary metabolites support growth, development and reproduction. Included in this group are carbohydrates, amino acids, polymers, lipids, etc.

Secondary metabolites are organic compounds of low molecular weight (often produced at less than 1% dry weight) that are not vital to growth but allow plants to attract pollinators and defend itself from herbivores and pathogens, but not from humans. Often, these compounds are what attract us to certain plants in the first place— they define its flavor and aroma. Secondary metabolites can be classified into three groups: Alkaloids, Terpenoids, and Phenolics.

Phenolic activity in artichokes
Anyone who has cut into an artichoke has witnessed oxidation; a reaction that takes place when phenolic compounds are combined with enzymes (through cutting or bruising) and exposed to oxygen, turning the exposed surface brown. Applying acid by rubbing with a lemon wedge only slows down the reaction. The only way to prevent it is to cut off its exposure to oxygen by submerging in water or vacuum sealing. Heating to temperatures above 212F/100C destroys the enzyme.

phenolic oxidation/ reaction to acid— both cups contain artichoke tea; the one on the right changes color after adding a few drops of lemon juice

Phenolic compounds are a rich source of phytochemicals (nonessential nutrients that are beneficial to health) such as antioxidants, flavonoids, and tannins. Artichokes are a primary source of cynarin, a compound that is believed to promote good health, including liver detoxification. Cynarin's ability to lower cholesterol was first documented In the 1970's, and many promising studies have taken place since.

Artichokes are notoriously difficult to pair with wine, thanks to cynarin and chlorogenic acid. These two phenolic compounds inhibit sweet receptors on our tongues, causing subsequent ingestion of foods or liquids to taste sweet. This taste perversion is similar to the one produced by miraculin, a protein found in miracle fruit, though it is significantly more short-lived and occurs only in a portion of the population, suggesting that it may be a genetic predisposition.

Cynarase, another enzyme found in artichokes, is believed to aid in digestion because of its ability to curdle milk. In parts of Europe and North Africa, coagulating milk for cheese with cardoon (a close relative of artichoke) is a long-standing tradition that is still carried out today.

Over a decade ago, while in Portugal, I learned that a popular cheese, Azeitao, is made from unpasteurized sheep's milk curdled with cardoon. It wasn't until earlier this year that I discovered that cynarase was responsible. As artichokes came into season, I began experimenting with their various parts, cooked in milk, with no success— lots of artichoke-flavored milk, but no curds. It wasn't until further research revealed that it is the mature thistle flower that is used to form milk curds that I tried again with the isolated choke (the undeveloped flower). Finally, I was able to produce enough curds to press into a small fresh cheese. These curds were very small, scarce, and soft, producing an impossibly fragile, but wonderfully herbaceous-flavored cheese. I haven't had much luck growing artichokes in Zone 5, but I'm willing to try again, if only to harvest the flowers. Barring that, there are other alternatives to explore— other flowers in the Cynareae tribe that do grow in my zone.

I wanted to build a dish around this very small, fragile, and delicious cheese that would represent all of the interesting things that I've learned about the artichoke. I started by pairing the milky cheese and the tender inner scales and ribbons of vegetal artichoke heart with the flavor of cherries. The ephemeral cherry blossoms hearken the nature of the artichoke-as-flower and whisper softly of benzaldehyde, while a soft gel of Villa Manodori Dark Cherry Balsamico gives the dish alacrity and vibrance. The artichoke tea, made by steeping the outer scales in boiling water, exhibits phenolic oxidation by changing from bright green to yellow when poured over the acidic cheese and gel. The herbaceous tea has a bitter edge that not only disappears, but is made sweet after taking a bite of the taste-altering heart.

crispy cream

Heating heavy cream in a pressure cooker produced some interesting results— most notably this airy, crisp texture which bears a remarkable similarity to aerated chocolate in appearance, flavor and texture.

Notes:

accelerated heat from pressure cooking causes fat to separate from solids
solids brown and form matrix around bubbling fat
fragile when hot
pliable while warm
hardens upon cooling

appearance: spongy, light to dark brown

texture: crisp , dry but perceived moist from retained fat, melting

flavor: deep, toasty, nutty, chocolate, roasted coffee, beurre noisette

citrus gama

My first inclination upon opening the box of citrus was to sit down and have myself a citrus feast, but that would have been purely indulgent and more than a little irresponsible. After all, it's not everyday that I have access to such rare and exotic jewels with at least one, the malaysian lime, of ambiguous origin. Gene Lester tells me that he planted it many years ago from seeds brought back from Malaysia and speculates that it may be an Egyptian lime.

I felt it was important to document their characteristics, if only for my own reference, as that has already been done to a greater extent over at Citrus Pages. Many of the photos and much of the information on the website is based on the fruit that Mr. Lester grows. After photographing, collecting data, and preliminary tastings, I was ready to get cooking.

New products, especially those of exceptional quality, always incite my creative monkeys. But with so many avenues and so little fruit, I had to reign them in and focus on a preparation that would capture the essence of the individual cultivars— not just the flavor of the juice, but also the rich aroma of the rinds.

Ever since stumbling on yuzu gama, I've been fascinated with the concept. I'll admit that using citrus as a kettle is a romantic notion. But it's also a practical one: the porous rind insulates, breathes, and permeates the contents with aroma.

The first thing I learned was that not all citrus make suitable cooking vessels. Those with bitter albedos— lemons, limes, grapefruit— impart unpleasant bitterness.

And yet those with thin, tender rinds— kumquats, clementines, mandarins— are surprisingly palatable and can be eaten along with the contents. Many of the fruits that I was given were petite— just the right size to snugly hold a scallop.

The Thomasville citrangequat (below left) is a cross between an orange and a kumquat. Like the kumquat, it has a sweet rind and tart pulp, though the fruit is larger (about 2" diameter), and the pulp is sweeter. After cutting off the top and bottom and removing the pulp, I steamed the rind for a few minutes to soften it. A scallop was stuffed into the citrus band and seared on both sides. The cintrangequat juice was reduced with saffron and blended with egg yolk and olive oil to form a mayonnaise that accompanies the scallop and steamed baby artichoke. The bright, fresh rind cut through the richness of the scallop and brought to mind the evanescence of spring.

The Silverhill mandarin (below right) is an Unshu satsuma with a rich, sweet flavor and aroma. It was hollowed out (an easy task as the pulp separates easily from the rind), stuffed with a scallop, seasoned with salt, szechuan pepper, a dab of butter and a sprinkle of its juice, then sous vide at 50ºC for 40 minutes. The scent escaping from the opened bag was incredible. It was glazed with a sauce made from the juices in the bag, reduced with the rest of the mandarin juice and mounted with sweet butter. Served with crumbled, dehydrated Cerignola olives and pureed black garlic, it made a sweet and resonant autumnal starter; rind and all.

Over the winter, my quasi-obsession with citrus has been interlaced with an increasing interest in old-school terrines, though up until now nothing has materialized.
For this terrine, I chose the Temple tangor, a cross between a tangerine and orange, because it was the largest specimen with a sweet rind. The hollowed out tangor was filled with a cylinder of foie, surrounded by black truffles folded into prepared sweetbreads (soaked, blanched, cleaned, pressed, seasoned), and bound with transglutaminase. The terrine was cooked sous vide at 65ºC for 90 minutes, pressed overnight, and sliced. Again, the mingled scents of foie, truffles and orange was not to be believed.
Other components are: pickled beet with tangor sections, brioche crouton, and a leaf of liquid salad made from watercress fluid gel, finished with olive oil and lemon juice.

Note: Although the rind of the tangor was sweet, it was a bit leathery. I had hoped that it would have softened more than it did in the sous vide process. If I were to repeat this dish— which I intend to (perhaps with a pate de campagne), I would precook the rind. Alternately, the rind could be used as a scented mold.

*Admittedly, foie, truffles and sweetbreads were rather decadent ingredients to experiment with, but these were left over from a job.

I don't recall the last time that I made a proper cassoulet, but I remember the first. It was after reading Paula Wolfert's "The Cooking of Southwest France" sometime in the mid 80's and feeling an overwhelming need to be connected to that place and its food. It was my introduction to duck confit, pork braised in milk, and the wantonly rich cassoulet. For years, I looked forward to the winter ritual that began with making lamb stock on a Friday night and culminated with a liberal topping of bread crumbs and duck fat on a Sunday afternoon. The crust was always the deal-breaker.
This cassoulet-inspired dish features Gigante beans cooked in duck stock, duck confit, and Cara Cara orange* segments, layered and baked together in the orange rind. The crust is a variation on chicken skin croquant, substituting duck skin, and dusted with orange zest and parsley.

*Cara Cara is a navel orange, a mutation that naturally occurred on a Washington navel orange tree, with sweet pink pulp. It was not in the box of citrus that chef Kinch sent me but I needed a fruit large enough to hold an entree-sized serving. Unlike the other dishes, this rind is used for aroma and presentation, not to be eaten.

buddha’s hand citron salt

My first inclination was to dehydrate the preserved Buddha's hand puree but some long forgotten piece of knowledge— an elemental fact, in fact— kept knocking at my logic, insisting that it would not turn out the way I thought.

It was the salt.

Salt does not evaporate. I learned that in third grade science class while standing over a pot of boiling salted water, watching the water vaporize and leave behind a film of salt clinging to the bottom of the pot.

Common salt is an ionic bond of sodium (Na) and chloride (Cl). When it is dissolved in water, the Na and Cl atoms pull apart and seem to disappear. Take away the water and the atoms reunite because they are electrostatically attracted to each other.

Remembering this put a spin on my intentions for the puree. Looking at it anew, I estimated that it was roughly 70% solids suspended in 30% water but there was no way to evaluate how much salt the preserved citron had absorbed. Judging from the taste— quite a bit. I had every reason to believe that if I removed the water from the puree I would be left with dehydrated flavor solids clinging to re-formed salt crystals, or an inherently flavored salt.

I would risk scorching the solids if I evaporated the water on a stove top. And I couldn't wait for the slow process of low temperature dehydration to find out. So I turned to the microwave.

After trying to heat a mass of the puree in the microwave, I quickly remembered something else I had forgotten: molten salt conducts electricity. Alarmed by the sparks flying around my 2-month-old microwave, I quickly removed it and thinly spread the puree on silpat and returned it to the microwave. It sputtered a bit, but no sparks. Ten seconds later, the puree had transformed to lacy fragments of crunchy, lemon-infused salt.

After my brain stopped reeling from possible uses, I was left with some questions:

Could the process be hastened by simply dissolving salt in a puree and dehydrating, or did the six-week-long preserving affect the outcome?
Did the acid in the lemon juice (used in preserving) come into play?
Did the re-formed salt crystals trap the solids or are they clinging to the crystals?
What is the yield point of a salt solution (i.e. how much salt can be added to water before it will cease to dissolve)
How much salt is necessary for the product to qualify as a flavored salt instead of a salty crisp?

thai shrimp cocktail

I've always poached shrimp in the conventional way: in a pot of simmering court bouillon. Sometimes I poach it in butter or olive oil, but then, that's confit, isn't it? Same with sous vide.

Recently, I was shown a different method by a culinary student at the restaurant, who learned it from another chef. His way is with residual heat. Instead of cooking the shrimp in the simmering broth, boiling broth is poured over the shrimp that's been spread out in a hotel pan. The pan is immediately covered tightly with plastic wrap and set aside. Depending on the size and quantity of the shrimp, it takes 10-15 minutes until they are perfectly cooked. What I like about this countertop cooking is that they are never tough or overcooked.

Peeling and deveining shrimp is a time consuming task. Sometimes, I buy them already deveined, but always with their shells on for flavor. Decapods (ten-footed crustaceans) carry their intestines on what appears to be their backs, but are actually their bellies. To remove the intestinal tract, the flesh along the belly must be slit open, leaving thin flaps that I find visually distracting when presenting them whole. These long, thin filaments peel away easily and are tasty morsels, though they rarely accumulate in quantities that would comprise a meal. These trimmings— the rare and esoteric by-products of cooking— are the cook's reward.

I think what I like best about Thai food is the balance of sweet, salty, tart, spicy and umami. Nowhere
is this best exemplified than in the sweet-sour garlic dipping sauce Nahm Jeem Plah Pao Ubon— a lively combination of lime juice, palm sugar, thai chilies, garlic, and fish sauce. It's an alarm clock of a sauce— it awakens the senses, makes you sit up and pay attention. I prefer it over cocktail sauce as a dip for poached shrimp. It's delicious poured over hot, grilled fish or steamed rice. In hot weather, I drizzle it over icy-cold watermelon or freeze it and rake it with a fork for a refreshing granita. It's so good that I could drink it, and I do—diluted with sparkling water and sometimes in a sake cocktail.
Using kaffir lime juice brings it to a whole other level, adding complex floral notes along with a bracing acidity.
I wanted to use it with the shrimp bellies and rice noodles in a cold salad, but because it is so thin, I was having a hard time getting the sauce to cling to it. It's not such a bad thing having a pool of it in the bottom of the dish to slurp up, but I was looking for a cleaner presentation. Of course, I could've thickened it with xanthan or ultratex, but looking at the rice noodles, I realized that they were the perfect vehicle to carry the flavor. With a nod to an entirely different cuisine— Italian— and the dish Spaghetti All'Ubriaco, where pasta is cooked in red wine, I cooked the rice stick noodles in the sauce. Infused with the flavor of Nahm Jeem Plah Pao Ubon, the noodles 'dressed' the salad neatly and cleanly.

Nahm Jeem Plah Pao Ubon
parts are by volume, not weight

3 parts nam plah (fish sauce)
2 parts water
2 parts palm sugar (or brown sugar)
1 part finely minced garlic
1 part minced fresh thai bird chili, or 1/2 part dried
3 parts fresh kaffir lime juice

Place all ingredients except for lime juice in a saucepan and bring to a simmer. When the sugar is dissolved, remove from heat and add the lime juice.

autumn leaves

I sometimes find myself out of synch with the seasons.

Like last week when I had to talk myself out of making spaghetti with jalapeno tomato sauce— a simple, summery sauce of barely cooked ripe tomatoes— because it was November.

Or, like yesterday, when I booked a holiday cocktail party and my head filled up with visions of sugarplums and other wintry fare.

Today, the rake calls. It's all about the leaves.

Raking leaves is definitely not my ideal of fun. But like all chores, once I find a rhythm, it becomes meditative. Not today though— I'm too preoccupied with cocktail parties… and hors d'oeuvres.

Cocktail parties prevail in the weeks between Thanksgiving and New Years. To my clients, a few hours of drinks and passed hors d'oeuvres means that they can entertain without the stress of formal dinner parties. There are no expansive (or expensive) menus, multiple place settings, or seating arrangements to deal with— just a well-stocked bar, a tasty selection of finger foods, and a capable staff to serve and execute.

I've seen a lot of hors d'oeuvre trends come and go in 20 years of catering. The once popular notion that anything wrapped in pastry or made in miniature was de rigueur is long gone. Modern tastes favor lighter fare with clean, bright flavors. (That said, I welcome the occasional request for pigs-in-a-blanket and sliders)

Presentation, too, has come a long way. I remember etched silver trays with elaborate floral arrangements complete with trailing ivy that the servers carried around like bouquets. The food became lost in these. Nowadays, I aim for vibrant food, simply arranged on white porcelain platters. When the food lacks visual interest, I don't hesitate to add something to the plate— but only if it makes sense and adheres to the philosophy that nothing belongs on a plate of food that is not edible, functional, or relevant.

As I tackle the leaves, I think about canapes and how they're a fitting model for the perfect hors d'oeuvre.

Canapes cover a broad range of foods that we eat with our fingers. They run the gamut from basic cheese and crackers to the old-school French vol-au-vents and barquettes. In between are smörgås (open-faced sandwiches), crostini, and savory tarts. Their common denominator is a dry, crisp base that makes them neat and easy to pick up and eat, and a moist, often creamy, topping. The textural contrast between the two— dry and wet, crisp and creamy— are a basic gustatory pleasure and primed for an update.

Cheese & Crackers

goat cheese on carrot-beet-parsnip crisps

And as the leaves pile up, I think, again, about crisp.

How to reinterpret cheese and crackers?
Start with the cracker and add flavor.

Crackers are basically flour, water, and fat. Certainly, doughs can be flavored with concentrated liquids or with dried flavor in modest amounts, but these introduced flavors are often muted by the large ratio of flour that is required to produce a crisp product. If the ratios are thrown too far off, we lose crisp.

Pure flavor can be extracted from produce with a juicer into liquid flavor and can be further concentrated or distilled, or the solids can be dehydrated and ground into powder. Potentially, these flavor-packed products can replace water and flour. But, of course, it's not that simple.

Juice is not just flavored water, it contains fine solid particles and compounds. Fruit juices may also contain acids, pectin and reactive enzymes that effect texture. Ground dehydrated solids may resemble flour but do not possess the gluten that will allow it to behave like milled wheat. Luckily, we are not limited to wheat flour— or even starches from grains— to produce crisp.

There are other starches that gel liquids. They are so effective that only small amounts are needed. They don't interfere with base flavors because they are odorless and colorless. The gels, when dehydrated, form flexible films that turn crisp when heated. Technically, these are called glasses.

Unlike raking leaves, glasses are fun to play with.

Ultratex is a tapioca-derived modified food starch that thickens liquids much like cornstarch, but does not require heat to activate. Adding 2-3% of Ultratex to a cold, thin liquid will instantly tighten it into a sauce. Thicker gels (5%) are quick to dehydrate and form crisp brittle films that are slightly papery.

Tapioca Maltodextrin is also derived from the cassava root. It is a mildly sweet polysaccharide. TM is best known for its ability to stabilize fats and transform them into powders. It forms slightly stickier films than Ultratex. When the two are combined, (at a rate of 18% TM to a 5% Ultratex gel) they form sturdy glasses that when baked at a high temperature during the final stage of dehydration (while they are still flexible) they make the most stable glasses, even in the presence of humidity.

Methylcellulose (A types) and Hydroxypropylmethylcellulose (E, F, and K types) also form films that dehydrate to glasses. Methocel glasses differ from Ultratex and TM in that when they are finished at a higher temp (100C), they turn from shiny and transparent, to matte and opaque.

Texturally, all of these additives produce thin, brittle crisps.
Visually, the methocel crisp looked most like a cracker, albeit,a fragile one.
It needed more bulk.
Aeration gives the illusion of bulk without actually adding any.
Methocel F types are used to create and stabilize whipped things.
Problem solved.

making a mold of autumn leaves out of silicone plastique

Juice crackers:

Bring 230g juice and 80g sugar or isomalt (isomalt is less sweet) to a full rolling boil. If the juice is not acidic, up to 10g of lemon juice can be added for flavor and balance. Remove from heat and allow to cool completely. In a small bowl, blend together 6g Methocel F50 and 8g Ultratex 8. Drop the powder blend into the center of the juice mixture. Cover the clump of powder with the blades of an immersion blender and blend until dispersed. Hydrate in the refrigerator for 4-6 hours, or overnight. With a mixer, blend until light, foamy, and opaque. Spread on silicone sheet or molds and dehydrate until film can be peeled off in one piece. Return to silicone and bake at 225F (100C) for 10-15 minutes. Immediately remove and bend or form into desired shape, supporting until it cools and hardens. Crackers can be made ahead and rebaked briefly to crisp.

To be clear, I use the term 'cracker' loosely. These are not crackers in a conventional sense— they lack flakiness. More accurately, they closely mimic the texture of a tuile or gaufrette wafer, but with the pure flavors of carrots, beets, and parsnips, un-muted by starch.

I'm dreading the acre of leaves that still need to be gathered and disposed of.
In joyful procrastination, I've created another pile of leaves in the kitchen.
The irony is not lost on me.

As always, nature inspires.

This time— dehydrated pumpkin in a fresh ginger root cake. This sheet, because it contains solids, is more of a chewy leather than a brittle crisp and converts to a soft, melting texture in the moist environment of the batter.

On the left are random strips embedded in the batter. On the right, strips were layered horizontally. Notice how the as the cake rose, it broke and disrupted some of the sheets. Interesting pattern, but I was going for a layered cake look. Next time, I'll try laying them in vertically.

Besides adding visual and textural interest, I think the true merit of this technique is in producing a cake with a baked-in filling. Now, to figure out how to get the frosting in there too.
