Notes

Ingredients

Chicken

  • 1½ lb Boneless, skin-on chicken thighs, cut into 1-inch pieces
  • 2 Tbsp Soy sauce
  • 1 Tbsp Shaoxing or Taiwanese rice wine
  • 1 tsp Sugar
  • ½ tsp Five-spice powder
  • ½ tsp White pepper
  • 3 cloves Garlic, grated
  • 1 tsp Ginger, grated
  • 1 Egg
  • 1½ cups Coarse sweet potato starch (or tapioca starch)
  • 1 cup Thai basil leaves
  • Neutral oil for frying

Salt-pepper seasoning

  • 1 tsp Kosher salt
  • 1 tsp White pepper
  • ½ tsp Five-spice powder
  • ½ tsp Chili powder or cayenne
  • ½ tsp Sugar

Instructions

  • Mix soy, rice wine, sugar, five-spice, white pepper, garlic, ginger and egg. Toss with the chicken and marinate 1 hour to overnight.
  • Stir the seasoning ingredients together.
  • Heat oil to 325°F. Dredge chicken in sweet potato starch, pressing so the coarse bits stick; rest 5 minutes so the coating hydrates.
  • Fry in batches 4 minutes until pale golden. Drain.
  • Raise oil to 375°F and fry again 1 minute until deeply crisp.
  • Toss the basil into the oil for 5–10 seconds (stand back, it spatters) and drain.
  • Toss chicken and basil with the seasoning and serve hot.
