Begin by slicing the chicken into small, bite-sized pieces.

In a small bowl, mix together potato starch, garlic powder, and salt. Coat the chicken evenly with this dry mixture. Refrigerate the coated chicken for at least an hour, or even overnight if preferred.

In a heavy-bottomed pan, heat about 3/4" of vegetable oil. If using a food thermometer, aim for an oil temperature of 175 degrees Fahrenheit. If not, medium heat should suffice.

Carefully drop the coated chicken pieces into the hot oil and fry until they turn a light golden brown, typically around 8-10 minutes. Remove them from the oil using a slotted spoon and place them on a plate lined with paper towels.

Allow the chicken to rest for 1-2 minutes, then return them to the oil for an additional 2-3 minutes, or until they achieve a crisp, golden-brown exterior.

While the chicken fries, mix all the ingredients for the Hawaiian sauce in a large bowl.

Once the chicken is cooked to perfection, toss it in the Hawaiian sauce until each piece is evenly coated.

Serve and enjoy your delicious homemade Hawaiian chicken!
