Japanese Fried Chicken
Chicken: 10 ounces boneless thighs
Marinade: Mince one 1½-inch piece ginger; mix with 3 tablespoons soy sauce and 1 tablespoon sake. Marinate chicken in sauce, 30 minutes.
Coating: Dredge chicken pieces in about ½ cup potato starch (katakuriko) or cornstarch. Pan fry chicken until done and set aside.
Sauce: Combine in a small skillet: 1 tablespoon each rice vinegar, soy sauce and finely chopped green onion. Add 1 teaspoon grated ginger, a pinch of sugar and a few drops sesame oil. Heat on medium heat, stirring, until the sugar dissolves. Add chicken and stir. Serve sauce with lemon wedges on the side. Let chicken and sauce cool completely or eat directly.
