Karaage Crispy Japanese Fried Chicken

Cut the chicken thighs into approximately 1.5-inch bite-sized pieces. In a medium bowl, combine the soy sauce, sake, mirin, grated ginger, grated garlic, and sesame oil. Add the chicken pieces to the marinade, ensuring each piece is well coated. Cover the bowl and refrigerate for at least 30 minutes, or preferably 1-2 hours for deeper flavor.

In a separate shallow bowl, whisk the lightly beaten egg. In another shallow bowl, combine the potato starch and all-purpose flour, mixing them well. This combination helps achieve the signature crispy texture of Karaage.

Remove the marinated chicken from the refrigerator. Take each piece of chicken, dip it first into the beaten egg, allowing any excess to drip off, then dredge it thoroughly in the potato starch and flour mixture, pressing gently to ensure a good coating. Place the coated chicken pieces on a wire rack or plate, ensuring they do not touch.

Heat the vegetable oil in a large deep pot or Dutch oven to 340°F (170°C). Carefully add the coated chicken pieces in batches, making sure not to overcrowd the pot. Fry for 2-3 minutes until the chicken is lightly golden and cooked through. Remove the chicken with a slotted spoon and place it on a wire rack set over a baking sheet to drain excess oil. Let it rest for 5-10 minutes.

Increase the oil temperature to 375°F (190°C). Return the rested chicken pieces to the hot oil for a second fry in batches. Fry for another 1-2 minutes, or until they turn a deep golden brown and are extra crispy. This double-frying technique is crucial for achieving the perfect crunch and keeping the chicken juicy inside.

Remove the Karaage from the oil and place it on a clean wire rack to drain briefly. Serve the crispy Japanese fried chicken immediately with fresh lemon wedges on the side for squeezing, and a dollop of Japanese mayonnaise if desired. Enjoy this delightful dish as an appetizer, a side, or part of a bento box.
