I Learn How to Make Tofu and Yuba

I have never had a burning desire to make my own tofu before, but a tutorial with Mitsuhiro Narita, a professor at the Tsuji Culinary Institute in Osaka, and chef at David Bouley's Tribeca kaiseki restaurant Brushstroke, actually has me contemplating it.

The event, held earlier this week, was the second-to-last Japanese cooking class in a series at the Bouley Test Kitchen just down the street from Brushstroke and Bouley.  The cheerful title of the class was "Egg, Tofu, Yuba and Some More!"

There was a lot more, but the tofu and yuba making was a highlight. Maybe you won't think it's worth the bother, but here's how you do it: Wash and soak soy beans overnight in water in a 1:1 ratio. The larger the beans the better, and if you can get some from Hokkaido you've really got it made. They are the best, according to Narita sensei.

The next day, you turn the whole thing into a paste in a food processor or blender, doing this in batches if necessary. Key warning: Don't taste this paste! Apparently very bad things will happen to your stomach if you do.

Next, put 6 cups of water in a large pot (or if you are changing amounts, 3:1 ratio of water to soybean paste). Bring the water to a boil, or really the first suggestion of a boil, then add the paste and mix it over high heat. There will be a lot of foam or awa, which you will have to keep skimming off. Also make sure you scrape the bottom of the pot as you mix. As soon as the soybean paste water mixture comes to a boil, turn the heat down low and cook for 7 minutes while continuing to skim foam off the top.

Turn the mixture into a cheesecloth lined sieve and squeeze out as much of the liquid as possible.Return the strained liquid to the pot. At this point you can make yuba, the delicious skin of the tofu, by pouring a small amount of the soy milk in a flat pan and heating it at 80 degrees celsius (170 degrees fahrenheit) until a top layer starts to form, just like the skin on heated milk. Lift the layer off with a chopstick and you've got yuba! Narita sensei made a delicious dish of battered, fried soft shell crab with yuba-ankake sauce, the latter made with dashi, mirin, light soy sauce and kudzu powder to thicken it.

To make tofu, you'll need, nigari, a natural coagulant derived from sea water that consists mostly of magnesium chloride, available in Japanese food markets. For 2 cups of soy beans, use 4 tablespoons, stirred in while the liquid is kept at a steady temperature of 70 celsius (158 degrees fahrenheit.). It works like magic. As soon as you stir in the nigari, the tofu begins to thicken, at which point you turn it out into a strainer lined with cheesecloth and gently squeeze out the excess liquid. The taste is very fresh and unadulterated.

Since there are no preservatives at all in this tofu, it only lasts about a day. To best appreciate your fresh tofu's pure flavors, serve it with a little grated fresh ginger, some chopped scallions, and a little soy sauce.

Not many Japanese people make their own tofu, Narita sensei told us, but recently a machine has come on the market in Japan that makes the process super-easy, with temperature controlled settings similar to a rice cooker. Perhaps this will be the next fad, just like yogurt makers in the '70s, and the current cocktail and paleta-making fads. How about tofu cocktails and yuba pops?

   

Brustroke Kaiseki, Chef's Pass at Bouley

Two nights ago, I had the chance to visit Brushstroke, the very Japanese Tribeca kaiseki restaurant from chef David Bouley, in collaboration with the Tsuji Cooking Academy in Osaka, Japan. The joint effort goes back 18 years, when Bouley first met Tsuji presidentYoshiki Tsuji, whose father founded the school and authored the seminal Japanese cookbook Japanese Cooking: A Simple Art. In order to bring the spirit of Japanese cuisine to New York, professors from the academy, kitchen equipment, ingredients and ideas have wended their way from Japan to Tribeca, making Brushstroke possibly the most authentic Japanese dining experience you can have in New York City at the moment.

Bouley says the collaboration is an extension of the way he’s always thought about cooking. The Japanese like him, he noted, because he’s a farmer at heart and he’s been doing seasonally driven kaiseki-style dinners since 1985, when he served 12- and 15-course small plate dinners on  custom-made Limoges china.

The Brushstroke space (formerly Danube), designed by the Japanese firm Super Potato and its lead designer Takashi Sugimoto, is a honeyed, mellow space, one wall of which is composed of the page-ends of 2,500 books stacked in criss-cross patterns and tinted to mimic the natural striations of wood. Chef Isao Yamada and mixologist Gen Yamamoto are creating exciting dishes and drinks that feel cutting edge modern but with the fanatic attention to detail and technique of the best Japanese restaurants. Among the dishes we sampled: “stinky” and creamy fermented tofu; truffled chawan-mushi (savory egg custard) with sea urchin; lobster claw tempura with two kinds of salt, curry and green tea, and a selection of pristinely fresh sushi. 

The clean, clear flavors extend to Brushstroke's cocktail menu as well, where heirloom tomatoes, grapefruit, ginger and green peas have all found their way into Yamamoto’s inspired cocktails. My grape tomato concoction was a beautiful shade of pink-red, subtle and delicious.

Back at Bouley, I got a peek at a room called the “Chef’s Pass.” In the process of expanding his kitchen space, the chef created a wondrous, salon-like room decorated with the kinds of gorgeous antique, artisanal and one-of-a-kind finds that he seems to amass in his sleep (he and chef Jody Williams are alike that way). The novelty is the 65-inch flat screen TV, where private dining groups can partake of their dinner while conversing, via Skype, with the purveyors who supply Bouley: master saké brewers in Japan, vintners and cheese makers in France and farmers in the Catskills or the Berkshires. Tours cheese maker Rodolphe Le Meunier, Meilleur Ouvrier de France (the highest honor awarded artisans in France), is such a good sport he’ll get up at 4 a.m. to chat with Bouley diners and explain his methods.

Chef's Pass allows Bouley to educate his patrons while feeding them in style, to introduce the hard-working farmers and craftspeople who make his kind of restaurant possible. Yet the chef takes a jaundiced view of the current “farm-to-table” movement, saying, “it’s what farmers have been doing for ten generations where I grew up in New England." While this "reinvention" of age old practices is nothing new, "it's a good thing," he adds, because it brings home the message that "people should not underestimate the value of the farmer."
