Taiwanese Popcorn Chicken

Step 1
Mix chicken, garlic, soy sauce, ginger, five-spice powder, white pepper, salt, vinegar, and cayenne pepper together in a large bowl until well combined. Let marinate for 10 minutes.

Step 2
Heat oil in a deep-fryer or large saucepan to 400 degrees F (200 degrees C).

Step 3
Whisk egg in a small bowl until smooth. Place dry tempura mix into a second small bowl. Dip chicken pieces one at a time into egg, then dredge in tempura mix, shaking off any excess.

Step 4
Working in batches, lower chicken carefully into hot oil and fry until golden brown, 5 to 8 minutes. Transfer to a paper towel-lined plate to drain and season with salt and pepper.

Step 5
Transfer chicken to a platter and garnish with basil leaves and green onions.
