Zaru soba

ざるそば: chilled buckwheat noodles on a bamboo tray with a kombu-shiitake dipping sauce

Zaru soba (ざるそば) is the simplest and most loved way to eat buckwheat noodles in Japan, served chilled on a bamboo tray (zaru) with a small cup of dipping sauce. You pick up a mouthful of noodles, dip them, and slurp. The usual tsuyu sauce is made with bonito; this one gets its savoury depth from kombu and dried shiitake. Refreshing on a hot day, with grated wasabi, spring onion and a little nori. Chef's tip: the ice-water rinse is not optional. It washes off the surface starch and tightens the noodles so they're slippery and firm; soba shops call this 'shime', the finishing chill.

Method

0/5 done
  1. Step 1: Soak ⅛ oz kombu (dried kelp) and 2 dried shiitake mushrooms in ¾ cup water for 10 minutes, then bring slowly to a simmer in a small pan. Remove the kombu just before it boils.

    5 min
  2. Step 2: Add 4 tbsp mirin, 4 tbsp soy sauce and 1 tsp sugar and simmer for 3 minutes. Strain, discard the shiitake (or slice them for a topping) and cool the sauce, then chill. It keeps in the fridge for a week.

    3 min
  3. Step 3: Bring a large pan of water to the boil, add 7 oz dried soba (buckwheat) noodles and stir so they don't stick. Cook following the packet, usually 4–5 minutes, until tender with no hard core. Add a splash of cold water if it threatens to boil over.

    5 min
  4. Step 4: Drain into a colander and rinse under cold running water, rubbing the noodles gently between your hands to wash off the starch. Finish in a bowl of iced water for 30 seconds so they turn firm and glossy. Drain very well.

  5. Step 5: Pile the noodles on bamboo trays or plates and scatter with 0.5 sheet nori. Pour the chilled sauce into small cups and serve 2 spring onions, 1 tsp wasabi paste and 1 ¾ oz daikon radish on the side to stir into the sauce as you eat.

Boiled pasta

The basic method for any dried pasta, from penne to spaghetti. A large pan of salted boiling water keeps the pasta from sticking, and you cook it only until just done, with a little bite left. Use it in salads, bakes or with any sauce.
