01 - Whisk together mochiko, cornstarch, soy sauce, sugar, eggs, garlic, ginger, green onions, sesame oil, salt, and black pepper in a large mixing bowl until smooth.
02 - Add chicken pieces to the marinade. Toss thoroughly to coat. Cover and refrigerate for at least 4 hours, or overnight for optimal flavor development.
03 - Fill a deep pot or large skillet with about 2 inches of vegetable oil. Heat to 350°F.
04 - Remove chicken from marinade, allowing excess to drip off. Fry in batches, turning occasionally, until golden brown and cooked through, approximately 5–7 minutes per batch.
05 - Transfer fried chicken to a paper towel-lined plate to drain. Repeat with remaining chicken. Serve hot, garnished with green onions, sesame seeds, and lemon wedges if desired.
