Japanese Agedashi Tofu Deep Fry and Sauce Architecture

Ingredients

• 600 g kinugoshi (silken) tofu, Otokomae Kinutofu or fresh nigari-set artisan tofu preferred; cut into 6 equal blocks
• 60 g katakuriko (potato starch), for dusting; do not substitute wheat flour
• 1 litre neutral oil, for deep-frying
• For the tsuyu
• 400 ml ichiban dashi
• 40 ml mirin
• 40 ml soy sauce
• 20 ml sake
• To finish
• 80 g daikon, finely grated, excess liquid pressed out
• 20 g fresh ginger, finely grated
• 2 stalks negi (Japanese spring onion), finely sliced on the diagonal
• 10 g katsuobushi (bonito flakes), added at table, not in the kitchen
• 4 leaves shiso, placed in bowl beneath tofu for aromatic lift

Method

1. 1
   Cut the kinugoshi tofu into six equal blocks. Lay each block on a double layer of paper towels, cover with further paper towels, and place a light, flat weight on top. Leave for 30 minutes. The tofu is sufficiently dry when no further moisture transfers to the paper — the surface must feel dry to the touch, not merely damp.
2. 2
   Combine the ichiban dashi, mirin, soy sauce, and sake in a small saucepan. Warm over a low flame to approximately 60°C. Test against the inner wrist: the liquid should feel comfortably warm, not scalding and not lukewarm. Hold at this temperature without allowing the tsuyu to approach a simmer — boiling tsuyu will collapse the crust the moment the tofu is placed in it.
3. 3
   Heat the frying oil in a deep, heavy vessel. For the double-fry technique: bring oil to 160°C. Working in batches of two or three blocks, dust each tofu block in katakuriko immediately before it enters the oil — the starch is applied at the last moment, never in advance, as potato starch absorbs surface moisture rapidly and will clump if left to sit. Lower each block carefully into the oil. Fry for 1 minute. Remove, rest on a rack for 30 seconds. This is where the dish lives or dies: return the tofu to oil now raised to 180°C and fry for a further 60–90 seconds until a thin, translucent, glass-like shell has formed across the entire surface — not opaque, not golden-brown, but a pale, glassy casing that holds its shape when lifted. Remove and drain briefly.
4. 4
   Place a single shiso leaf flat in the base of each warmed serving bowl. Set the fried tofu blocks immediately on top. Ladle the warm tsuyu around and partially over the tofu — enough to surround the base without fully submerging the blocks.
5. 5
   Place a small mound of grated daikon and grated ginger on top of each tofu block. Scatter the sliced negi. Carry the bowls to the table and add the katsuobushi there: the thin flakes will tremble and lift in the warmth rising from the tsuyu. The dish must reach the guest within 2–3 minutes of the tofu entering the broth — within this window, the crust shatters cleanly before beginning to dissolve into the liquid. Beyond it, the textural contrast is lost.
