Start off by making the spices mix. Mix the five spice powder, chili powder, white pepper, and sugar in a small bowl. Set aside.
Add the chicken in a large bowl with the grated garlic, egg, soy sauce, and rice wine. Mix it all together. Then, add the spices mix (from step 1) into the chicken mixture and combine it all together. Cover and marinate in the fridge for at least 30 mins, or up to overnight.
Coat each chicken piece in tapioca starch evenly and let it sit for 5 minutes to ensure the coating doesn’t fall off.
In a deep wok/pan over medium-high heat, heat up the neutral oil for frying. Once the oil is heated, fry the Thai basil for 30 seconds to 1 minute. Remove and set aside. This makes the oil more fragrant!
Fry the chicken for 5 minutes, or until golden brown and the chicken is cooked through. Remove, and deep fry for a second time for an extra 2 to 3 minutes. This makes it even crispier! Remove and place the chicken in a serving dish.
