Japanese Agedashi Dofu Tofu Frying Technique and Sauce Architecture Revisited

Ingredients

• 600 g kinugoshi (silken) tofu, drained and surface-dried
• 30 g katakuriko (potato starch), sieved for dusting
• For the tentsuyu
• 240 ml dashi
• 20 ml soy sauce
• 20 ml mirin
• For the garnish
• 60 g daikon, finely grated
• 2 myoga ginger, finely sliced
• 1 pinch katsuobushi (bonito flakes)
• 1 litre neutral frying oil, for deep-frying; temperature 175–180°C

Method

1. 1
   Cut the silken tofu into four equal portions. Wrap each piece in 3–4 layers of paper towel and press under a light weight for 20 minutes. Unwrap, transfer to a rack, and leave uncovered in the refrigerator for a further 10 minutes. The surface should feel dry to the touch, without visible moisture or condensation; any surface wetness at this stage will cause the starch to clump rather than dust evenly.
2. 2
   Combine the dashi, soy sauce, and mirin in a small saucepan at a ratio of 12:1:1. Warm gently to 60°C. Do not allow the sauce to boil. Hold at this temperature until service. At 60°C the sauce will create progressive, gentle softening of the crust from below; a hotter sauce steams the crust immediately and collapses the textural arc.
3. 3
   Dust each piece of dried tofu through a fine sieve with the katakuriko. The coating should be barely visible — a pale frost on the surface, with no visible accumulation in folds or on the base. Hold each piece and tap away any excess. This is where the dish lives or dies: a crust too thin will not form at all; a crust too thick will produce a doughy shell that does not soften gracefully in the tentsuyu. The correct coating registers as a faint opacity on an otherwise translucent surface.
4. 4
   Heat the frying oil to 175–180°C. Verify with a thermometer. Below 170°C the tofu will absorb oil before the surface sets; above 185°C the exterior locks before the interior warms through. Gently lower each dusted tofu piece into the oil. Fry for 2–3 minutes. The exterior should turn ivory with the palest golden tinge. Remove from the oil as soon as that pale colour is reached — browning must not develop.
5. 5
   Transfer the fried tofu immediately to warmed shallow bowls. Pour the warm tentsuyu around each piece to approximately 30% of its depth — enough to begin softening the base crust while leaving the upper surface temporarily intact. Crown with grated daikon, sliced myoga, and a pinch of bonito flakes. Serve without delay: the textural arc from crispy to soft runs for approximately 2 minutes after the sauce is added.
