Just a decade ago, Sonoko Sakai was burned out. That's when she washed her hands of a career in the film industry to focus on something more restorative: the art of making soba noodles. Even after writing an award-winning cookbook, Japanese Home Cooking, and leading countless workshops and webinars on soba making, Sakai still cherishes the process of kneading, cutting, and preparing the Japanese buckwheat noodles by hand, which requires a special focus.

"All of my senses are working—that's what I love about soba. You have to be particularly alert," says Sakai. For Sakai, the process of making soba is a soothing act that's all about trusting her senses, whether that's running her fingers through crumbly buckwheat flour and making slight adjustments to the dough, or tasting and tweaking the simmering umami-rich broth destined for slurping up with the cooked noodles. Even her signature instructions for how to bring the water and buckwheat flour together in loose, circular motions with one's hands ("Wax on, wax off," she says jokingly) come down to learning to rely on intuition. "You put water in the flour, you start mixing it, and you have a conversation with the dough. It's a humbling experience.

"Whether you're working with a soba kiri, the specialized knife used to cleave dough into strands of noodles in one motion (see "The Slice Is Right," below, for Sakai's favorite one), or relying on a trusty chef's knife to do the trick, Sakai emphasizes that from- scratch soba noodles can be in any- one's wheelhouse, regardless of experience or equipment. The ingredients are simple; the process is rewarding. "I want people to feel relaxed about Japanese food. There's not one thing I enjoy about soba making—it's everything," says Sakai. "Every time I make it, it's a celebration."

5. Fold Dough

Sprinkle half of dough with tapioca starch; fold in half lengthwise. Sprinkle again, and fold in half to create a 9-inch square with 4 layers of dough

6. Cut Noodles

Using a ruler or cutting guide (pictured; see "The Slice Is Right," below), cut dough into thin noodles. Tap on cutting board to remove excess starch.

7. Cook & Cool Noodles

Cook noodles according to recipe directions. Using a strainer, transfer noodles to a colander set in a bowl of ice water. Remove colander, and rinse noodles under cold running water. Drain and rinse again. Serve soba noodles cold with Crispy Duck and Hot Dipping Sauce.
