grated daikon radish (daikon oroshi)optional, about ½ tbsp per portion
Japanese chili powder (shichimi togarashi)optional
Instructions
Take a small saucepan and add 150 ml dashi stock, 1 tbsp Japanese soy sauce (koikuchi shoyu), 1 tbsp mirin, 1 tsp sake and ¼ tsp salt. Mix and bring to a boil over a medium heat. Let it bubble for 30 seconds, then lower the heat. Make slurry in a separate bowl with 1 tbsp water and 1 tsp potato starch (katakuriko). Pour the slurry into the sauce and stir continuously over the low heat until slightly thickened, remove from the heat and set aside.
Drain 300 g firm tofu and wrap it in kitchen paper. Place it on a heatproof plate and microwave for 1 ½ minutes at 600W.
Unwrap the tofu and cut into approximately 12 pieces about 3cm/just over 1 inch cubes. Dry the surface of each piece with kitchen paper and sprinkle with 1 pinch salt.
Preheat your cooking oil (enough to submerge the tofu) to 170 °C (338 °F). Mix 2 tbsp all-purpose flour and 2 tbsp potato starch (katakuriko), roll each piece of tofu in the mixture until coated all over.
In separate tray, add the other 2 tbsp potato starch (katakuriko) and mix with 1 tsp water to make "hailstones". When the oil is ready, roll the tofu in the hailstones and place them directly into the pot one by one.
Fry the tofu for 3 mins or until lightly golden, turning half way. Transfer to a wire rack to drain the excess oil. Use this time to reheat the sauce if needed.
Place the crispy tofu in serving bowls and drizzle the sauce around it, avoid the top if you want to preserve crispiness. Top with finely chopped green onions, grated daikon radish (daikon oroshi) and Japanese chili powder (shichimi togarashi) to taste. Enjoy!
Notes
Coat the tofu in "hailstones" only after the oil reaches 170°C (340°F). Tofu's moisture dissolves the starch clumps within minutes.Listen for doneness. The sound shifts from a loud crackle to a quiet, high-pitched sizzle as the crust sets. Aim for pale straw-gold, not deep brown.Make the sauce before you fry, and keep it hot. The broth should be around 70 to 80°C when it hits the tofu.Pour the broth around the tofu, not over it, and serve immediately.Some softening at the broth line is expected, not a failure. Agedashi tofu is designed to have a texture gradient.
