To make crispy, juicy Japanese Karaage, marinate bite-sized chicken pieces in soy sauce, ginger, garlic, and sake, then coat them in potato starch and fry twice for optimal crispness.
Achieving perfect Karaage involves several key steps:
Marination: Cut chicken thighs (or breast, though thighs are juicier) into bite-sized pieces. Marinate them for at least 30 minutes (or up to overnight) in a mixture of soy sauce, grated ginger, minced garlic, and sake (or mirin). The marinade tenderizes the chicken and infuses it with flavor.
Coating: The traditional coating is potato starch (katakuriko). This creates a light, crispy crust. Ensure the chicken pieces are evenly coated, shaking off any excess starch.
First Fry: Fry the chicken in oil heated to around 160°C (320°F) for about 3-4 minutes, until lightly golden. This cooks the chicken through.
Rest: Remove the chicken from the oil and let it rest for a few minutes. This allows the internal temperature to equalize and the juices to redistribute.
Second Fry: Increase the oil temperature to 180°C (356°F) and fry the chicken again for 1-2 minutes, until golden brown and crispy. This second fry is crucial for achieving that signature Karaage crispiness.
Drain and Serve: Drain the fried chicken on a wire rack to maintain its crispness. Serve immediately with lemon wedges or your favorite dipping sauce.
Don't overcrowd the frying pan. Frying in batches ensures the oil temperature doesn't drop too much, which can result in soggy Karaage. Maintain the oil temperature for optimal results.
