1Preparation
- Wipe the kombu with a damp cloth and soak it in the water for 30 minutes.
- Wrap the tofu in kitchen paper and set a heavy plate on top for 20 minutes to press out the water.
- Finely grate the daikon and gently squeeze out the excess water by hand.
- Grate the ginger, slice the green onion very thinly and cut the nori into strips.
- Cut the tofu into 8 even cubes and pat the surfaces dry again.
2Cooking
- Heat the kombu water slowly until small bubbles appear around the edge, then lift out the kombu before the water boils.
- Add the soy sauce and sugar to the broth and stir until the sugar dissolves, then keep it warm on the lowest heat.
- Heat the frying oil in a deep pot to 170°C; without a thermometer, dip in a wooden chopstick — steady small bubbles should rise around it.
- Coat the tofu cubes in starch on all sides, shake off the excess and fry 4 at a time until pale golden and crisp.
- Lift the tofu onto a wire rack to drain, then fry the second batch the same way.
3Serving
- Place 2 tofu cubes on each plate and pour the warm broth around them without covering them.
- Top the tofu with a small mound of grated daikon and ginger, scatter over the green onion and nori, and serve right away.
💡 Tips & common mistakes
- Common mistake: coating the tofu long before frying — the starch soaks up moisture, turns gummy and won't crisp. Coat each cube just before it goes into the oil.
- Don't let the broth boil with the kombu still in it, or it turns slimy and bitter.
- Pour the broth around the tofu, not over it, so the crust stays crisp for the first bites.
🔁 Substitutions
- Firm tofu: silken tofu for a softer texture, though it is more fragile and needs very gentle handling.
- Kombu: a light vegetable stock can replace the kombu broth.
