Stone-Grilled Tofu

#83 妙品 Exquisite

English Interpretation

Heat stones well over fire. When hot, place thinly sliced tofu on the stones. Drizzle with a little soy sauce and wait for it to cook. The heat of the stones gives it an exceptional sear.

Notes & Annotations

Ishiyaki (石焼) is the technique of cooking on heated stones. Ishiyaki-imo (stone-roasted sweet potato) remains a beloved street food in Japan. The method predates metal cookware.

English Recipe

Ingredients

  • firm tofu 豆腐 1 block (350 g)
    一丁 Cut thin and patted dry
  • soy sauce 醤油 to taste
    Drizzled on while cooking

Method

Serves 2

1. Heat a flat stone slab (or a heavy cast-iron plate as substitute) in the oven at 250 °C for at least 30 minutes until blazing hot.
2. Cut firm tofu into thin slices, about 8 mm thick. Pat very dry.
3. Carefully place the tofu slices on the hot stone. They should sizzle immediately.
4. Drizzle a few drops of soy sauce over the tofu as it cooks.
5. Cook until the underside develops a deep, even crust — about 3–4 minutes. Flip once if desired.

The stone provides intense, steady radiant heat that you can't replicate with a pan — the crust is more even and the interior stays softer. Ishiyaki (stone cooking) predates metal cookware and survives today in dishes like ishiyaki bibimbap.
