playing with fire and water

sashimi rose and a celebration of fermentation

My first batch of shoyu has been brewing for six months now and it's just hitting its stride. I've tended it faithfully, stirring at least once a week and skimming off harmless surface mold as it formed, but for the longest time it was barely more interesting than a pot of bean soup. It wasn't until the end of its fourth month that I noticed a marked difference as the mold quit and the moromi (solids) began congregating on the surface, concealing clear dark liquid beneath. When I stir it now, the aroma is intoxicating in the nuanced complex way of fermented things. Soon, I'll begin filtering small batches to mark its progress and though I don't yet know when it'll be done, I expect it to continue improving with time.

While I wait for the shoyu, there's a fresh batch of mirin to celebrate— and real mirin is a just cause for celebration. I'll restrain myself from a full-on rant about what passes for mirin in the commercial market; you have only to read the list of ingredients and if it begins with glucose and ends with corn syrup, you should wonder why you're being asked to pay four dollars for ten ounces of sugar water. Hon- mirin (true mirin) contains no added sugar, though it is remarkably sweet— the result of koji/rice saccharification. The aroma of hon-mirin is unlike anything else, fruity and floral with a delicate flavor that can be sipped like a fine sake*. In fact, I see great potential for hon-mirin in cocktails and as an alternative dessert wine/spirit. And, an unexpected perk of brewing mirin is the lees— a heady cream that is left after pressing the moromi and before filtering.

The celebration continues with hishio, a hybrid of mugi (barley) miso and lactic-fermented fruits and vegetables. Hishio is made entirely with barley koji that is fermented in water and salt for about a week before adding vegetables (asian pear, cucumber, and eggplant in mine) that are seperately fermented in salt. The loose, miso-type condiment is then fermented in a warm environment and is ready in four months.

In even less time, a lively yuzu kosho can be made in a just over a week at room temperature. This particular batch was made late last year, when piney green yuzu were still available. They were zested with a microplane and blended with the restrained heat of charred, minced shishito peppers and salt. After it fermented for eight days, I blended in the last of the kinome leaves just before my tree went dormant for the winter. I'm sad to see the bottom of my jar come into view as fresh yuzu won't be available again until the end of the year, but I'm equally gratefully for the bounty; a consequence of soil, bacteria, and patience.

* most mirin brewers add water to the rice, koji, and shochu to bring the finished alcohol down to about 14%. I used straight shochu (20%), no water, and can only assume that my mirin comes in at between 17%- 20% alcohol by volume.  

a living soup

Milkweed is a useful plant, entirely edible in its early stages. The young shoots are a delight when they emerge in the spring. Later, the tender young leaves are worth seeking out, but it's the reproductive parts that start out as buds, then open into sweet-scented flowers, and develop into tender-crisp pods that interest me most.
 
By mid-summer the plant toughens as it directs its energy into producing seeds. Though the mature pods are too cellulosic to consume, they're beautiful to look at. Pulling one apart, I am reminded of the recurring motifs found in nature: the seeds, perfectly shingled like feathers and fish scales, the 'cobs' composed of lustrous filaments— finer than silk— that unfurl into ghostly flowers to carry the seeds into perpetuity. Genius!

Although I had managed to harvest and pickle some flower buds while they were in season, I thought I had missed the window for the young pods until I found a stand of stunted plants growing in deep shade. The pods must be blanched to draw out their milky sap. I served them as crudites with a kefir-based dip and made some new milkweed (and kefir) converts. I saved a few to garnish a cold soup that I'm excited to tell you about. 

All summer long my blender had been busy making raw, green gazpacho-style soups. Packed with good flavor and nutrients, they were a savory on-the-go alternative to smoothies, yet with some prudent garnishes they easily transitioned to more formal meals. Mostly, I made them with whatever was fresh and on hand, with variations of the basic components. Here's my framework recipe with percentages based on weight:

45% english cucumber, unpeeled
20% liquid- water, white wine, veg broth
15% fruit- green grapes, melon, avocado, white peach
8% fat- evo, almond oil, avocado oil
3.5% greens- lettuce, herbs, arugula, spinach, sorrel
3% nuts- almonds, macadamia, pistachio, sunflower seeds
2.75% acid- citrus juice, vinegar
2% aromatics- garlic, shallot, scallion
.75% salt

A few weeks ago, I made what would likely be the last cold soup of the year. I packed the blender with cucumber, nasturtium leaves, Crenshaw melon, almonds, garlic, scallions, and olive oil. I didn't have any open white wine or vegetable broth, but I did have a lot of fresh kefir whey left over from making kefir cheese. Since it was more than moderately acidic, I used it to replace both the liquid and the acid in the soup. In doing so, I realized that I was adding an ingredient that was alive with lactic acid and yeast, and that if given the right conditions (time and temperature), they would be capable of fermenting the soup. After consuming part of the soup, I put the rest on my front porch on an 85℉ day. Four hours later, the soup was notably transformed. The texture had lightened, almost to the point of being 'fluffy'. The sharp edges that I remembered from the soup that I had consumed earlier had rounded out (except for the acidity), yet the flavor had amplified. The difference was like listening to a CD versus a attending a concert; the raw soup was good, but the fermented soup tasted alive. 

   

 

kefir

I have a friend who claims that regular consumption of kefir will provide her with a long, healthy, disease-free life. I hope she's right.

It seems that most kefir enthusiasts drink it for the health benefits (which are substantial) but almost apologetically claim that the flavor is an acquired one. Sure, if you're not open to the taste of sour milk, kefir can be offputting. But, by making it yourself, you can control the degree of sourness— from mildly tangy to sharp and effervescent.

For the uninitiated, kefir is fermented milk, cultured with kefir grains. The gelatinous grains are a matrix of sugar, protein, fat, and ash that harbor a garden of yeast and bacteria. It is the yeast that sets it apart from other milk cultures that are predominately bacteria.

Making kefir is as simple as adding the grains to milk (about 1 tablespoon of grains per 2 cups of milk) and allowing it to ferment at room temperature for a day or two. When the desired texture and flavor are achieved, the grains are strained from the kefir and recycled to start a new batch. If those directions sound vague, they are intentionally so. Even with careful weighing and control of temperature, the results are not always consistent. I've come to believe that this is because kefir grains are living organisms that operate with dual microbes and that the speed and efficiency with which they culture a new batch of kefir is largely dependent on their active state at the time of introduction. For example, I've found that after straining the grains from a completed batch of kefir and immediately adding them to fresh milk, fermentation (detected by the onset of a sour flavor) begins more rapidly than when a batch is started with grains that have been stored in the refrigerator between batches. 

With so many variables, I no longer bother with weights and temperature, I just set it out on the counter and let it do its thing. Sometimes I catch it when it turns creamy and just begins to acquire a tang. Sometimes I let it ripen until it curdles and precipitates whey, at which point the curds can be drained to form a soft, tangy cheese. My favorite thing is to cover it tightly while it ferments to trap the CO2 released by the yeast until it gets fizzy. Milk champagne is a wonderous thing!

amazake strawberry kinome

It was on a blustery winter afternoon that I first sampled amazake. It came in the form of a traditional Japanese beverage, served warm with a sprinkle of grated ginger. Learning that it was essentially just fermented rice and water, I was amazed at the depth of flavor and sweetness that koji had coaxed out of the rice. And there was a richness about the way that it felt in my mouth that reminded me of dairy. It was, I was told, the vegan eggnog.

Recently, I had a visitor come to my home to see my newly remodeled kitchen. Because he writes about food, I wanted to cook for him and was eager to showcase some of the products that I had fermented. For dessert, I made an amazake ice cream based on the beverage, using coconut water for added flavor. It was really an experiment, as I was curious about the texture of churned and frozen amazake. The result was not as creamy as I had hoped and the inherent sweetness had muted to a mere whisper— which typically occurs with freezing. We both agreed that it showed promise, but needed work. 

We also agreed that the flavor of strawberries and kinome with the amazake was quite special, so that part of the dish would remain intact.

Days later, I made a new ice cream with pureed amazake, cream, and sugar. It was a vast improvement over the original, but I couldn't help but feel that I had missed an important opportunity.

As someone who cooks customized food for a living, the upsurge of food intolerances is a salient concern. Coeliac disease, lactose intolerance, and food allergies are serious conditions that I have learned to make allowances for. Then there's an ever-increasing number of people who choose to refrain from entire food groups such as dairy or meat, or follow 'lifestyle diets' that exclude white powders and saturated fats. Add to that, the political eaters who prohibit foie gras, veal, unsustainable fish, factory farmed proteins, and unorganic produce; or picky eaters who refuse to eat (for example) anything with garlic or onions, and you can begin to see why chefs are so frustrated— some to the point of choosing to make NO allowances.

I don't have that luxury.

When a guest at a dinner party unexpectedly announces that there is something on the carefully planned menu that they can't or won't eat, I have to accommodate them. No excuses. 

The upside is that when you feed someone with special dietary needs a delicious and satisfying meal that doesn't offend their bodies or minds, they are exceedingly grateful. Altruism aside, a happy client is always a boost to the ego.

Over time, I've learned to make adjustments to fit most diets, but vegan desserts continue to challenge me. In a pinch, I can turn to fresh fruit and sorbet or granita, but that often feels like a copout. So I reexamined amazake's potential to add texture, natural sweetness, and moisture to desserts that otherwise rely on dairy products and refined sugars, and I decided that an ice cream was a good place to start. To the pureed amazake, I added coconut milk for richness, rice syrup for added sweetness, and guar gum to improve the mouthfeel. The addition of sichuan pepper was specific to this dish to enhance the flavor of strawberries and kinome. 

While I'm pleased with how the amazake ice cream turned out, if I were given a choice between the sweet cream version and the vegan one, I would invariably choose the former.

I'm grateful that I have that luxury.

amazake

Making amazake is perhaps the most overt example of saccharification that I've ever witnessed. 

Take some cooked rice, blend it with koji (about 2:1 by volume), embrace them in warmth (100-140F), and in less than half of a day the koji will have efficiently digested the rice's starch, converting it into simple sugars. The result is stunningly sweet and full of character. 

Traditionally, amazake is used as a sweetener or blended with hot water and served as a warm drink, but I'm just starting to investigate its potential in other arenas. 

kasu bread

Leavened bread is probably the last thing anyone would associate with washoku tradition. Indeed, when we take a protracted view of Japanese cuisine, bread is a johny-come-lately.

It was late in the 16th century when the first Europeans—the Portuguese—settled in Japan, bringing with them Western religion, science, technology, and food. Although the Japanese quickly assimilated cake (bōlo) and fried food (tempura) into their cuisine, the Portuguese bread was too sour and chewy for their taste and not widely adopted. Nonetheless,  it captured their imagination and the word pan (from the Portuguese pão) stuck. 

Fast forward 300 years to 1871: the samarai Yasubei Kimura opens a bakery, Kimuraya, in Tokyo, with the aspiration of producing baked goods for the Japanese palate.  Kimura realized that making European-style bread in Japan would be challenging. Leavened doughs were a new concept and wheat flour and yeast were scarce. After many failed attempts using alternate sources of yeast, Kimura hired Kodo Katsuzo, who developed a dough leavened with kasu (sake lees), giving birth to anpan, a hybrid of manjū (a Japanese derivative of Chinese mochi) and light, cottony, Dutch-inspired bread dough, encasing a filling of anko (sweet red bean paste). After the emperor gave it his seal of approval, anpan became the first widely accepted Japanese bread. 

It was kasu's potential to leaven bread that first drew me to it. I found many references to sakadane, the liquid kasu starter used in the original anpan, but couldn't find a recipe or process, so I developed my own. Using wild cultivated yeast as a model, I made a starter from rice flour, water, and kasu. It took 8 days of feeding and stirring for it to become fully active— a considerable effort for what turned out to be a less than remarkable loaf of bread.

I suppose I could have started over and tweaked the recipe, but with all of the lengthy fermentation processes that I have currently working, I wanted something more immediate. I wanted bread— conspicuous with kasu, and mellow with rice—that I could make start-to-finish in a day. To that end, I made a new dough, adding yeast to hasten the process, and folded bits of kasu and fragrant basmati rice into the risen dough. For that shortcut, I make no apologies— to you, or to myself— because the bread was truly remarkable.

Kimura's anpan is but one example of how cross-cultural influences inform and develop cuisine by borrowing ideas, processes, and/or ingredients, and tailoring them to the tastes of the people that it will feed.

My kasu bread goes one step further; it closes the circle. 

The Japanese were inspired to create a national bread from their introduction to leavened bread via the Portuguese. Inspired by sakadane, I borrowed kasu from the Japanese and applied it to a bread from my own heritage: Portuguese pão.

How does it taste?
It tastes richly personal,
sweet with history,
seasoned with a touch of irony.

kasu bread

starter:
54g compressed kasu
180g water
100g bread flour
.4g active dry yeast

dough:
175g bread flour
1.6g active dry yeast
5g salt
5g rice bran oil
5g mirin

solids:
100g cooked, drained, and cooled basmati rice
40g compressed kasu, cut into small bits

starter: In a blender, blend together the kasu and water until homogenous. Place the flour in a bowl and stir in the yeast. Pour kasu water into center and stir with a spoon to form smooth batter. Cover loosely and set aside at room temperature for 2-3 hours until batter forms bubbles.
dough: Place flour, yeast and salt into the bowl of a stand mixer fitted with paddle attachment. Mix on low speed to blend dry ingredients. With the mixer still on low speed, slowly pour in the active starter. Turn speed to medium and mix for 2 minutes. Add the rice bran oil and the mirin and mix 2 minutes more. Replace paddle with dough hook, turn speed up to medium high and knead dough for 5 minutes. Lightly oil a large bowl. Scrape dough into bowl and turn upside down, so that top of dough is oiled. Cover with plastic wrap and set aside at room temperate until doubled in volume, about 1 1/2-2 hours.
solids: Punch dough down to deflate and turn out onto floured board. With fingertips, press dough into a rough rectangle, about 1/2" thick. Evenly sprinkle rice over dough, followed by bits of kasu. Starting at wide end of rectangle, roll dough in a tight spiral to form a log, and seal the ends. Cover dough with lightly oiled plastic wrap and let rise at room temperature for 1 1/2 hours, or until nearly doubled in size.
40 minutes before baking, place a baking stone on floor of oven and preheat to 232C/450F. When dough has risen, transfer it to a floured baking peel and place on heated stone in hot oven. Mist the oven 3-4 times with water in a spray bottle during the first 10 minutes of baking. After 15 minutes, turn the oven down to 204C/400F, and continue baking for 15-20 minutes longer until deep golden brown. Remove from oven with a peel and allow to cool on a rack.

 

kasu-cured scallop

Kasu is a by-product of sake. Also known as sake lees, it is the separated and pressed solids that remain at the end of the fermentation process. Consisting of rice, koji, residual yeast, and a small amount of alcohol, kasu can sometimes be found as a soft paste or, more readily, as square compressed sheets. It has a delicate floral yeasty aroma.

Kasu zuke is another type of Japanese pickles where food is embedded in a paste made from kasu, mirin, sugar and salt. Typically, the process is applied to white fish for a brief curing, or to fresh vegetables for longer periods.

These live scallops were so pristine that I wanted to keep them clean and chose to wrap them in kasu sheets instead of a paste. After spiral cutting them into thin, even strips, they were sprinkled with mirin, covered with kinome, then sealed between two sheets of compressed kasu. Looking like large ravioli, they cured in the refrigerator for 24 hours,. They emerged from their kasu cocoon all fragrant and delicious.

cured shad roe

With the other shad roe sac, I'm attempting a multi-stage curing process. Here it is so far:

First, it was brined for 2 days in a 3% salt solution. Then it was embedded in a thick layer of sea salt for 3 days. Next, it was allowed to dry on a rack in the refrigerator for another 3 days until the surface was thoroughly dry. After brushing off the excess salt, it was embedded in a thick layer of red miso, covered and set in the refrigerator to ferrment for 2-3 months. That's where it is now.
After that, it will be cold smoked, then dehydrated until it is hard as wood.
The intention is to transform the shad roe into a botarga-like product with the complexity of katsuobushi.
The hope is that it will be delicious. 

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.

*Want to know your state's fish? Here you go.

 

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!
