Creating your own Taiwanese Popcorn Chicken is simple when you follow these steps:

1. Marinate the Chicken: In a mixing bowl, combine chicken pieces, soy sauce, rice wine, minced garlic, minced ginger, ground white pepper, and five-spice powder. Marinate for at least 20 minutes, or overnight for deeper flavor.

2. Prepare the Coating: In another bowl, mix sweet potato starch, all-purpose flour, baking powder, and a pinch of salt. This will be the coating for the chicken.

3. Heat Oil: In a deep frying pan or wok, heat enough oil over medium-high heat for frying. The oil should be about 1-2 inches deep.

4. Coat the Chicken: After marinating, take pieces of chicken from the marinade, allowing excess to drip off. Dredge in the flour mixture, ensuring an even coating.

5. Fry the Chicken: Carefully place the coated chicken pieces in the hot oil. Do not overcrowd the pan; fry in batches if needed. Fry for 4-5 minutes until golden brown and crispy.

6. Drain Excess Oil: Once the chicken is cooked, use a slotted spoon to transfer it to a plate lined with paper towels to absorb excess oil.

7. Fry the Basil (Optional): You can also fry fresh basil leaves in the same oil for 10-15 seconds until crispy. They add an aromatic touch to the dish.

8. Season: Lightly sprinkle with additional salt to taste.

9. Serve: Plate the crispy chicken and garnish with fried basil leaves. Enjoy immediately for the best crunch!
