Shojin dashi

Kombu and shiitake stock

Shōjin dashi (精進出汁): kombu and dried shiitake stock, the fish-free base of temple cooking

Zen temples in Kyoto and Kamakura build their whole cuisine on this stock: kombu kelp and dried shiitake soaked in cold water until the liquid turns golden and deeply savoury, with no bonito at all. It is the vegan dashi for miso soup, simmered vegetables, noodle broths and dipping sauces, and every vegetarian Japanese recipe on this site can use it. The common mistake is boiling the kombu, which releases slime and bitterness; it should never go beyond a gentle simmer, and taking it out just before boiling gives the cleanest flavour. Chef's tip: soak overnight in the fridge (mizudashi) for the best, roundest flavour with no effort, then keep the softened shiitake for a simmered dish.

Method

0/5 done
  1. Step 1: Wipe ⅓ oz kombu gently with a damp cloth to remove any grit. Put it in a jug with 4 dried shiitake mushrooms and 4 ¼ cups cold water.

  2. Step 2: Leave to soak for at least 30 minutes, or ideally 6–12 hours in the fridge, until the shiitake are soft and the water is pale gold.

    30 min
  3. Step 3: For a quick, stronger stock, pour everything into a pan and heat slowly over a low heat for about 10 minutes. Lift out the kombu as small bubbles appear around it, just before boiling.

    10 min
  4. Step 4: Simmer the shiitake for 5 minutes more, then strain. Use straight away, or chill for up to 3 days or freeze in portions for a month.

    5 min
  5. Step 5: Squeeze and slice the shiitake and use them in a simmered dish or rice; the kombu can be cut into strips and simmered with soy and sugar into a relish.

Vegetable brown stock

A hearty stock that's simmered for 2 hours, then blended and strained, so the potato gives it body. Its deeper flavour suits thick soups, gravies and stews. Freeze it in portions so it's ready when you need it.

Yaki onigiriGrilled rice balls

Yaki onigiri (焼きおにぎり) are rice balls grilled until they form a crisp, toasty crust, then brushed with soy sauce glaze. They are eaten all over Japan, at izakaya, at barbecues and from the freezer section, as a snack or with miso soup. The inside stays soft and steamy while the outside crackles. Best eaten hot, straight from the pan. Chef's tip: let the shaped rice balls dry for 10 minutes before they go in the pan. A drier surface forms a better crust and won't stick, and the glaze goes on only at the end so it doesn't burn.

Bean sprouts

Sprouting whole green grams makes them crunchier, quicker to cook and more nutritious. All you need is muslin, water and a warm spot, and they're ready in 3–4 days. Use them in salads, bhel, usal and stir-fries. Any other whole pulse sprouts the same way.
