Creating Taiwanese Popcorn Chicken can be an easy and enjoyable process by following these straightforward steps:

1. Marinate the Chicken: In a bowl, mix together the chicken pieces, minced garlic, ginger, soy sauce, rice wine, five-spice powder, black pepper, and salt. Ensure every piece is well-coated. Cover and marinate for at least 30 minutes.

2. Prepare the Breading: After marinating, prepare a dredging station with the beaten egg and cornstarch in separate bowls.

3. Coat the Chicken: Take each marinated chicken piece and dip it in the beaten egg first, allowing excess egg to drip off. Then, coat it thoroughly in cornstarch, ensuring it is well-covered.

4. Heat the Oil: In a deep skillet or fryer, heat oil over medium-high heat. The oil should reach about 350°F (175°C) for frying.

5. Fry the Chicken: Carefully add the coated chicken pieces to the hot oil in batches. Avoid overcrowding the pan, which can cause the temperature to drop.

6. Cook Until Golden: Fry for about 5-7 minutes or until the chicken turns golden brown and is cooked through. Use a slotted spoon to transfer it to a plate lined with paper towels to drain excess oil.

7. Optional Final Fry: For added crispiness, you can do a second fry for 1-2 minutes.

8. Garnish and Serve: Place the crispy chicken on a serving plate and garnish it with freshly fried basil leaves and a sprinkle of chili powder if desired.
