Zaru Soba – Cold Japanese Noodles

Soba noodles are a delicious way to explore the authentic flavors of Japan. Simple but sophisticated, they are perfect for both lunch and dinner.

Soba noodles, one of the cornerstones of Japanese cuisine, are made from buckwheat flour, which gives them a characteristic nutty flavor and firm texture. Traditionally enjoyed cold with a dipping sauce or in a hot broth, they are not only mouthwateringly tasty, but also packed with nutrients.

These deliciously earthy strands have a rich history that dates back to the Edo period (1603-1868) in Japan. Initially considered a luxury, soba became popular among the masses for its nutritional value and its ability to prevent beriberi, a disease caused by vitamin B1 (thiamine) deficiency, thanks to its buckwheat composition.

The tradition of eating soba originates from the belief that the slender noodles symbolize a long and healthy life. Soba is traditionally served in various styles: like here, chilled with a dipping sauce (Zaru Soba), in a hot broth as a noodle soup, or stir-fried. It’s especially consumed during the New Year’s Eve celebrations in Japan, a customknown as Toshikoshi Soba, symbolizing the cutting away of the old year’s misfortunes.

Begin by picking up a few strands of noodles with your chopsticks, then dip them lightly into a cold tsuyu sauce—a savory blend of dashi, soy, and mirin. Avoid soaking; a gentle dip enhances flavor without overpowering the soba’s delicate taste.

Between bites, cleanse your palate with a sip of tsuyu or a bite of wasabi and green onions mixed into the sauce. It’s a refreshing, interactive meal, deliciously simple and elegant.

How to Make Zaru Soba – Cold Japanese Noodles

Preparing the Soba Noodles:

1. Boil Water: Fill a large pot with 2 quarts of water and bring it to a rolling boil over high heat.
2. Cook Noodles: Carefully add the soba noodles to the boiling water, spreading them out. Stir gently to ensure they do not stick together. Wait for the water to return to a full boil, then lower the heat slightly to maintain a steady but gentle boil. Cook according to the package instructions, usually about 4-8 minutes.
3. Cold Water Shock: If the noodles start boiling over, add a cup of cold water to lower the temperature briefly. This technique, known as ‘yudane’, helps to cook the noodles evenly.
4. Check Doneness: Taste a noodle or check its texture; it should be firm yet tender, not mushy.
5. Rinse and Cool: Once cooked, pour the noodles into a colander and rinse them thoroughly under cold running water. This stops the cooking process and removes excess starch, ensuring the noodles are cool and firm.
6. Drain Well: Shake off the excess water and transfer the noodles to a tray. Cover with a damp kitchen towel to prevent them from drying out while you prepare the other components.

Preparing the Dipping Sauce (Tsuyu):

1. Dashi Stock: Dashi is a fundamental Japanese stock often made from kelp (kombu) and dried bonito fish flakes (katsuobushi). For beginners, instant dashi granules are a practical choice. Follow the package instructions to prepare 1 1/2 cups of dashi. Typically, you’ll dissolve about 1 teaspoon of granules in 1 1/2 cups of hot water.
2. Combine Ingredients: In a medium saucepan, mix the prepared dashi, soy sauce, mirin, and sugar. Place over medium-high heat and stir until the sugar dissolves. Remove from heat and let the sauce cool down. You can refrigerate it for a refreshing, cold dip.

Arranging the Dish:

1. Nori and Garnishes: Cut the nori sheet into thin strips using kitchen scissors. Chop the green onions finely and prepare wasabi paste by mixing the wasabi powder with a little water. Let it stand to develop its flavor.
2. Serve: Place the cooled noodles on individual plates or a communal serving dish. Sprinkle nori strips over the noodles. Serve the dipping sauce in small bowls or cups, and provide wasabi, grated daikon, and green onions on the side for guests to add according to their taste.
3. Enjoy: Traditionally, diners will add their preferred garnishes to the dipping sauce, then dip small bundles of soba into the sauce as they eat. Slurping is encouraged — it enhances the flavors and cools the noodles!

Recipe Notes:

• If you’re unable to find dashi granules, a simple soy sauce and water mixture can be a base substitution for the dipping sauce, though it won’t have the same depth of flavor.
• Be careful not to overcook the soba noodles, as they can become mushy quickly.
• Adjust the wasabi and garnishes according to your personal preference for spice and flavor.
