Ingredients
Method
- Cut the chicken thighs into 2-inch pieces, roughly walnut-sized, so they cook in the same time.
- Whisk the soy sauce, sake, ginger, garlic, and sesame oil in a bowl. Add the chicken, turn to coat, cover, and refrigerate for 30 minutes (up to 2 hours).
- Lift the chicken out and let the excess marinade drip back into the bowl. You want a thin film clinging to the surface, but the pieces should not be dripping.
- Stir the potato starch, flour, and salt together in a shallow dish. Coat each piece, pressing lightly, and set on a tray in a single layer. Rest 5 minutes so the coating hydrates and turns slightly tacky.
- Pour oil 2 inches deep into a heavy pot and heat to 170°C (340°F). Fry in two batches, 3-4 minutes per batch, turning once, until pale gold. Lift out to a wire rack and rest 3 minutes.
- Raise the oil to 180°C (355°F). Fry the chicken a second time, 45-60 seconds per batch, until deep golden and crisp. Return to the rack, sprinkle lightly with salt if you like, and serve immediately with lemon wedges, Kewpie, and cabbage.
Notes
Note 1: Marinate 30 minutes minimum and 2 hours maximum. Under 30 minutes the flavor sits on the surface; past 2 hours the salt in the soy sauce starts breaking down the chicken's texture.
Note 2: Potato starch (katakuriko) fries up craggier and stays crisp longer than cornstarch. If you only have cornstarch it still works, but expect the crust to soften sooner.
Note 3: Rest the dredged chicken 5 minutes before frying. The coating hydrates and turns tacky, which keeps it bonded in the oil instead of sloughing off.
Note 4: Do not skip the second fry. The first fry cooks the chicken through; the short second fry at 180°C (355°F) is what drives off surface moisture and locks in the shattering crisp.
Note 5: Drain on a wire rack, never on paper towels. Paper traps steam under the crust and undoes the second fry in minutes.
Note 6: Use chicken thighs, not breast. Thighs stay juicy through the double fry; breast dries out.
