pickled shad roe

The turning of the seasons brings a new palette of flavors that are never more ephemeral than in spring. For a few short weeks I gorge on newborn onions, particularly those of the sweet Vidalia variety. Grilled, roasted, braised— I can't seem to get enough of them before they're gone.

The season for shad roe is equally fleeting and depends on where you live. Like salmon, shad are anadramous fish that live in salt water, but ascend rivers and streams to breed when the waters warm. Along the east coast, they begin running in January in Florida, and continue through to June in Canada. In Connecticut, where the American shad (Alosa sapidissima) is the state fish*, the month-long season is nearly over.

And shad roe's perishability is more evanescent than its season. I only buy it when I know that I can cook and serve it the same day. Yet, I couldn't walk away from the remaining pair of sacs in the fish case and when I asked the fish monger to wrap those as well, I knew I would be enjoying them days later.

pickled shad roe

1-2 shad roe sacs
1Liter/1.05 qt cold water
85g/3 oz kosher salt
56g/2 oz brown sugar
3.5g/½ tsp. pink curing salt (optional, but will give the roe a rosy color)
1 bay leaf
10 black peppercorns
3.5g/1 tsp mustard seeds
3.5g/1 tsp whole coriander seeds
1g/½ tsp dried thyme
rendered bacon fat

Place roe sac(s) in a non-reactive container and chill. Bring water, salt, sugar and sodium nitrate to boil in a stainless steel saucepan. Remove from heat and allow to cool completely. Pour cooled brine over roe. Add remaining ingredients, cover and pickle in the refrigerator for 3 days. Remove roe from brine, discard brine and rinse container. Return roe to container and cover with fresh cold water. Chill for 12 hours.
Remove roe from water and pat dry with paper towels. Place roe sac(s) in sous vide bag. Add 28g/1 oz rendered bacon fat per sac. Vacuum and seal bag. Cook at 64C/147.2F for 40 minutes. Remove roe from bag and pat dry with paper towels. Chill before serving.

egg yolk cheese

These are 65C hen egg yolks that have been cured in miso for two weeks. The longer cure renders them dark and pungent. Although they were firmer than they were at 5 days, they remained moist and sticky. In order to dry them out, they were wrapped in the cheesecloth in which they were cured and hung in the refrigerator.

These are the cured egg yolks after hanging for twenty days. They've became firm enough to slice or grate neatly, with the smooth, plastic-y texture of an aged gouda. Their flavor, too, is transformed— the aging process rounds out the sharpness of the miso, creating a mellow complexity of flavor with the texture of cheese. Delicious!

More yolks… this time, from hen eggs… cooked at 65C and cured for 5 days.

Well worth the time and effort for the sinuous luxury that it added to this humble dish of young root vegetables and shiitake dashi.

miso-cured quail eggs

The earliest tsukemono (Japanese pickles) are believed to have been made with miso. The simple process, known as misozuke, involves embedding food in a bed of miso and allowing it to cure for at least 3 months. The most prized misozuke are cured for a year or more.

Over the last several weeks, I've been curing a variety of plants and proteins in miso. My spare refrigerator is full of misozuke— bananas, apples, dried apricots and tomatoes, garlic, daikon, pumpkin, shiso leaves, kombu, bacon, pork skin and fatback, beef marrow, lamb breast, parmesan, gouda, and more. Though it'll be a few months before they're ready, I'm currently enjoying the egg yolks that cured in 4-5 days.

These are quail eggs yolks after 4 days of curing in red miso. Counter-clockwise from bottom is: a pair of raw yolks, 62C, 63C, 64C, and 65C in the center with part of the albumen still attached. After curing, the raw yolks collapsed and were soft and sticky, while the rest retained their shape. The differences in texture among the 62C-65C yolks were subtle— all of them reminiscent of soft cheese with a rich, umami flavor.

miso-cured oyster

Oysters can be cured in miso in less than a week. I left some to cure longer, but five days seemed to be the magic number for optimum flavor and texture in this particular batch. Of course, this could vary depending on the size of oysters and the type of miso used.

To make miso-cured oysters: Steam scrubbed oysters just until they open. Remove the oysters from shell and place them on paper towels to dry. If using shells for curing, sterilize them in boiling water for 5 minutes, then allow them to cool and dry. Spread a 1/2" thick layer of miso in the bottom of each shell. Cover miso with a layer of cheesecloth, then an oyster. Cover the oysters with cheesecloth, then another layer of miso, and finally, the top shell. Layer oysters in a sterilized container, cover tightly, and allow to cure in refrigerator for 3-7 days.

The assertive flavor of kombu and garlic is a good compliment to the meaty oyster and earthy mushrooms, brightened by refreshing bursts of cucumber provided by the ngo om (rice paddy herb).

After the oysters were gone, we happily nibbled on the aioli and mushrooms.

kombu aioli

6g garlic
3g salt
2 egg yolks
60g rice wine vinegar
200g olive oil
10g kombu powder*

Place the garlic, salt, egg yolks, and vinegar in a blender or food processor and processes until well blended. With the motor running, very slowly drizzle in the oil until thick and emulsified. Add the kombu powder and process briefly until blended. Scrape out aioli into a bowl, cover and let refrigerate for 2-3 hours to allow kombu to hydrate and flavors to mellow. Stir before serving.
* kombu powder can be made by grinding pieces of dried kombu sheets in a spice grinder to a fine dust.

mushroom crisps

small king oyster mushrooms lend themselves well to crisping because of their thick meaty stems.

With a vegetable peeler, shave thin slices of mushrooms by imbedding the blade of the peeler into the cap and dragging to the base. Lay the mushroom slices out in a single layer on a sheet pan and allow to air-dry for 1-2 hours, until their edges begin to curl. Lightly brush or mist the slices with a thin layer of olive oil. Bake in a 149C/300F oven for 4-5 minutes, or until they are golden and crisp. Lightly sprinkle with salt and serve immediately.

miso-cured kombu

120 days.
That's how long I'll have to wait to see what happens to kombu when it's cured with miso.
I expect the miso itself will also be interesting.

tekka miso

Tekka miso is a condiment traditionally made from burdock, carrots and lotus roots. The grated roots are slowly cooked in sesame oil, then blended with ground black sesame seeds, ginger, and Hatcho miso— a dark, long-fermented type of miso made entirely from soybeans. The paste is slowly cooked over a low fire until all of the moisture evaporates, resulting in a dry, crumbly mixture.

Prized in Japan for its flavor and aroma, tekka miso is reminiscent of chocolate and coffee. Not surprising as it, too, is a product of fermentation and roasting, with parallel complexity.

tekka miso
makes 200ml (¾ cup)

9g sesame oil
30g grated daikon
30g grated carrot
25g grated beet root
25g finely minced scallion
25g black sesame paste
6g microplaned gingerroot
130g hatcho or red miso

Line the bottom of a skillet with the sesame oil and set over medium heat. Add the daikon, carrot, beet root and scallion and toss to coat with the oil. Cook until vegetables just begin to take on color, then lower the heat to medium low and continue cooking until soft and tender, stirring often. Add the sesame paste and gingerroot, pressing into vegetable mixture until incorporated (it will form a clump). Cook for 2-3 minutes while spreading and turning the mixture, then blend in the miso. Spread the resulting thick paste in the bottom of the pan in an even layer. Turn the heat down to lowest setting and continue cooking for 20-30 minutes. Alternately, the mixture can be spread on a baking sheet and baked in a 65C/150F oven. In either case, turn and spread the mixture every few minutes until it is dry and crumbly. Cool before packing into jars. Store in refrigerator for up to 3 months.

miso adaptations

Spontaneous fermentation is the oldest form of 'cooking'. Long before man understood the chemistry of how microorganisms preserved his food and heightened its flavor while making him healthier, he learned to control and manipulate the process. Each culture developed their unique specialties based on indigenous ingredients. Early travelers borrowed techniques from their neighbors and assimilated them to what was available back home.

In this spirit, I've taken the time-honored process of making miso and adapted it to the bounty of ingredients that are available in the modern world to make these trial batches. The choices were not arbitrary— they needed to fit the protein/starch profile that koji requires to feed upon. In some cases, soybeans were added to the base ingredient to boost the protein content. Many borders were crossed, but no bridges were burned.

No doubt, some will fail, and some will succeed, but that's part of the fun of discovery. Ultimately, flavor will dictate which ones will be pursued.

miso

I was making miso when I heard the news about Japan. Sendai miso. I stopped to watch the footage on the same TV screen that, at any given moment, on numerous other channels, I could watch other horrific scenes played out. But this was real. It was happening. Days later, it's still hard to grasp the destruction… the devastation… the loss… the redesign of geography… the bending of time. And as the crisis escalates from a natural disaster to one made by man, I remain in awe of the grace and dignity of the people of Japan.

The label indicates the date of production and date of "first sample".
I expect it to take at least a year until it will be ready for use.

Miso is surprisingly easy to make. The hardest parts are: waiting six months to over a year for the fermentation process to complete, and procuring the koji. Although shoyu, miso and sake combined make up 2 percent of the GNP of Japan, there are only about six companies that produce koji, making it difficult to buy in small quantities. I purchased mine from naturalimport.com, but even they are currently out of stock. If you are an adventurous do-it-yourself'er, you can make koji by inoculating rice with tane-koji (Aspergillus oryzae spores), available from GEM cultures.

There are many types of miso, ranging from sweet white (shiro miso), light yellow (shinshu miso), sweet red (edo miso), to barley miso (mugi miso). They vary by ratios of soybeans:koji:salt and in length of fermentation. Sometimes, as is the case with mugi miso, barley (instead of rice) is inoculated with the tane-koji. I chose to make red (sendai miso) because it is what I use most in my kitchen.

PREPARING TO MAKE MISO:
   • To avoid contamination, sterilize everything that will come in contact with the miso.
   • Choose a cylindrical earthenware or glass vessel whose diameter is less than its height. The miso should fill the vessel by at least 80%.
   • Choose a lid to fit snugly inside the vessel. It should be rigid and flat and can be of any material, but porous or reactive material should be well wrapped and sealed with several layers of plastic wrap.

PREPARING SOYBEANS:
1. Rinse 397g/14oz dried organic soybeans under cool running water, then place them into a pressure cooker*. Add 1L/1qt spring water. Cook on high pressure for 40 minutes, then allow pressure to release naturally. Beans should be soft enough to crush easily. (*If pressure cooker is unavailable, soak beans in water for 8-10 hours, then bring to a boil with 2L/2qts spring water. Reduce heat and cook beans at a simmer for 4-5 hours, or until tender.)
2. Pour hot, cooked beans through a strainer, reserving the liquid. Allow to drain for 10 minutes.
3. For a rough, rustic texture, mash beans with a fork or a potato masher. For smooth texture, puree in food processor. Transfer beans to a non-reactive bowl.

PREPARING MISO:
4. Measure 454g/16oz of the reserved bean cooking liquid. Add 163g/5.75oz kosher salt. Stir.
5. Add mixture to mashed beans. Stir until well blended.
6. Check the temperature of the bean mixture. It should be no higher than 37.78C/100F. Set aside to cool, if necessary, then add 340g/12oz koji. Stir until well blended.

PREPARING MISO FOR FERMENTATION:
7. With clean hands, moisten the inside of vessel by dabbing the walls and bottom with wet fingertips. Sprinkle 3g/½tsp kosher salt inside vessel and distribute evenly with fingertips.
8. Pack prepared miso tightly into vessel, stopping between layers to press and release trapped air pockets. Smooth top of miso and sprinkle 6g/1tsp kosher salt evenly over surface.
9. Cover miso with a piece of plastic wrap, pressing onto surface and draping over rim of vessel. Secure plastic wrap to top of vessel with a rubber band or string, leaving a little slack to allow for compression.
10. Fit lid inside rim of vessel. Press firmly. Place a 1-1.5kilo/2-3lb weight on top of lid. Affix label to vessel with the date of preparation and the estimated date of completion.

FERMENTATION:
For natural fermentation (1-3 years)— Choose a clean, cool (not over 21C/70F), dry location that is well ventilated and not in direct sunlight, such as a garage, barn, or cellar. Elevate vessel so that it is not sitting on floor. Do not disturb miso for at least the first six months, except to monitor the level of tamari (liquid) that rises to the top. After one month, if there is no tamari, increase the weight on the vessel. If there is more than 1/2", decrease the weight. After six months, The tamari can be tasted for aroma and flavor, keeping in mind that it will be saltier than the finished miso. Surface mold is not harmful and can be scraped off, in which case the surface should be re-salted and covered with a clean piece of plastic. Continue to sample every three months until the flavor is mature and satisfactory. If at anytime the miso tastes or smells overly acidic, sour, or alcoholic, it should be discarded.

Miso can be fermented in under 6 months by storing in a carefully controlled environment between 21C/70F and 32C/90F, a process that is too detailed to cover here. For further information and inspiration on how to make and use miso, refer to the comprehensive "The Book of Miso", by William Shurtleff and Akiko Aoyagi.

koji

Do you know koji?
If you don't, you should— it's responsible for all kinds of deliciousness.

Koji is an unsung hero among molds. If you enjoy products like soy sauce, shoyu, mirin, miso, and sake, then you can thank Aspergillus oryzae, the filamentous fungus that transforms beans and grains into umami-laden powerhouses of flavor. It does so by producing enzymes that break down starches, proteins, and fats into simple sugars, amino acids, and fatty acids, preserving them, while making them more digestible and delicious. It is the same process that transforms milk into cheese, wheat into bread, grapes into wine— the elegant and complex miracle of fermentation.
