荞麦面，不只是面条

RENEE MONTAGNE, HOST: The Japanese cuisine known as washoku was recently named by the United Nations an Intangible Cultural Heritage. That's a craft or creative skill passed on from generation to generation. Tofu, mochi and miso are a few examples, but it's the buckwheat noodle or soba that many consider the humble jewel of Japanese cuisine.

It's not easy to find in the U.S. But as Sasa Woodruff reports, one woman in Los Angeles is helping preserve the craft of making soba.

SASA WOODRUFF, BYLINE: In a cooking classroom off a busy street in L.A., Sonoko Sakai, is teaching about the simplicity of making buckwheat noodles.

SONOKO SAKAI: Basically, soba is only two things: flour and water.

WOODRUFF: A handful of students gather around the slender Sakai as she shows them how to mix the flour and water together.

SAKAI: We want to distribute the water into the cells of the buckwheat and wheat flour as quickly as we can.

WOODRUFF: The key ingredient is buckwheat and despite its name is not part of the wheat family.

SAKAI: This is what buckwheat looks like.

WOODRUFF: The triangular brown seeds are actually more closely related to rhubarb or sorrel.

SAKAI: See how it's white?

UNIDENTIFIED WOMAN: Oh, yeah.

UNIDENTIFIED MAN: Yeah.

SAKAI: That's the flour.

WOODRUFF: One of the students who came to the class is Mikie Shioya. She's a native of Japan and wants to eat authentic soba here in the U.S.

MIKIE SHIOYA: Soba is my favorite food.

WOODRUFF: But finding genuine versions in the U.S. is difficult. The packaged noodles available in grocery stores are made mostly of wheat flour. And only a handful of restaurants stateside serve it up in the traditional way, meaning the chefs make the dough and cut and boil the noodles in front of customers. Shioya hopes to recreate that taste in her own kitchen.

SHIOYA: I don't know anybody who makes soba at home.

(LAUGHTER)

SHIOYA: But if you live in Japan, like, you can just go to the really good soba place. But here in L.A., there's nowhere to go, so like...

SAKAI: You get so desperate you have to make it.

(LAUGHTER)

SHIOYA: Yeah, you have to make it.

WOODRUFF: Sakai explains the beloved noodle is a Japanese creation, unlike, say, the Ramen noodle, which originated in China.

SAKAI: It came to Japan as a porridge. And the Buddhist monks who studied in China, had it during their long, meditative journeys and they brought it back to Japan. And the people in Japan turned it into noodles.

WOODRUFF: From start to finish, it takes Sakai only 15 minutes to make and cook the noodles from scratch. She can't imagine doing it any other way. For her, there's a joy in making something by hand. And while Sakai loves the taste, soba is more than just food, it's an art form.

SAKAI: It's a rhythm.

WOODRUFF: Sakai and the her students cut the noodles into long, slender strips as thin as matchsticks. They're dunked in boiling water for just a minute and then shocked cold in an ice bath.

The students get a new appreciation for the subtle flavor as they taste it plain, in broth and with soybean powder.

SAKAI: It's very much like wine 'cause it's like eating fresh fruit and you don't want to mask it with other things. So, yes, it's a very bland flavor. But if you acquire the taste for it and you begin to really appreciate the depth of soba, of buckwheat and the work of the artisans

WOODRUFF: And Sakai is going beyond just crafting and teaching soba, she's learning to grow buckwheat and even bought a stone mill to make her own flour.
