Ingredients
- 800 g boneless chicken thighs, skin on
- 3 tbsp soy sauce
- 2 tbsp sake
- 1 tbsp mirin
- 1 thumb ginger
- 3 cloves garlic
- 1 tsp sugar
- 1 egg
- 120 g potato starch
- 1 litre neutral oil, for frying
- 1 lemon
- Japanese mayonnaise, to serve
Instructions
- 1Cut the chicken into 4 cm pieces, keeping the skin on each one. The skin is where much of the crispness comes from.
- 2Grate the ginger and garlic. Mix them with the soy sauce, sake, mirin and sugar in a bowl, add the chicken and turn to coat.
- 3Cover and marinate for at least 30 minutes at room temperature, or up to 4 hours in the fridge. Longer than that and the soy starts to cure the surface and the texture turns firm.
- 4Beat the egg into the marinated chicken. The egg helps the starch cling in an uneven, craggy layer, which is exactly what you want.
- 5Put the potato starch in a wide bowl. Lift each piece of chicken out and press it into the starch, coating it heavily and squeezing gently so the coating grips. Shake off only the loosest excess.
- 6Let the coated pieces sit for 5 minutes. The starch hydrates slightly from the marinade and stops it falling off in the oil.
- 7Heat the oil to 160C. Fry in three batches for 4 minutes a batch, then lift onto a wire rack. The chicken will be pale and cooked but not crisp.
- 8Rest for 5 minutes and raise the oil to 190C.
- 9Fry each batch again for 60 to 90 seconds, until deep golden and hard-crisp. The first fry cooks the meat and drives out moisture; the second sets the crust. One fry cannot do both.
- 10Drain on a rack, salt lightly, and serve with lemon wedges and Japanese mayonnaise.
Karaage is the fried chicken of Japanese home cooking and izakaya menus, and it is noticeably different from the American or Korean versions: no buttermilk, no batter, no flour.
Potato starch is the coating
Katakuriko — potato starch — is nearly pure starch with no protein in it. Fried, it forms a thin, brittle, almost glassy shell rather than the soft bready crust that wheat flour gives.
It is also what makes karaage stay crisp longer at room temperature, which is why it works cold in a bento box.
Cornflour is the usual substitute and gets you most of the way there. Plain flour gives a completely different, softer result.
The egg is a binder
Beating an egg into the marinated chicken before dredging is not universal but it is common, and it does a specific job: it gives the starch something sticky to grip, producing an uneven, craggy surface with more area to crisp.
Straight from marinade to starch gives a thinner, smoother coating. Both work; the egg version is knobblier and better.
Two fries
The same principle as Korean fried chicken. 160C first, long enough to cook the meat through and drive water out of the surface. Rest. Then 190C for a short, hot second fry that dehydrates the coating into a hard shell.
Resting between fries matters — it lets moisture migrate from the interior to the surface, where the second fry can drive it off. Straight from one to the other and you trap steam under the crust.
Do not over-marinate
Soy sauce is a strong brine. Thirty minutes to four hours gives depth. Overnight makes the chicken firm, dense and too salty, because the salt has drawn out moisture and begun to denature the surface proteins.
This is the opposite of the advice for most marinades and it is worth remembering.
Thigh, with skin
Breast meat dries out at frying temperatures and karaage is unforgiving of that. Thigh has enough fat and connective tissue to stay juicy through two fries.
Leaving the skin on each piece is standard and adds a great deal — it renders slightly and crisps into the coating.
Nutrition
Around 620 calories a serving. Frying at the correct temperature matters for more than texture: chicken fried at 160 to 190C absorbs considerably less oil than chicken fried at 140C, where the coating stays porous for longer.
The lemon is not a garnish. Squeezed over just before eating, its acidity cuts the fat and is the traditional way it is served.
