1: Wash chicken and pat it dry. Season with salt and black pepper, then coat with potato starch.
2: Air fry, pan fry, or deep fry the chicken. If pan frying, do it on medium-high heat for ~8 minutes, then flip and fry for another ~8 minutes until golden brown. Remove and set aside.
3: In the same pan (or a different one), heat up 2 TBSP of oil. Add 4 TBSP unsalted butter and melt it slightly. Then add minced garlic and minced shallots. Cook for 2-3 minutes until fragrant.
4: If using red pepper flakes, add them now. Then, add 1 ¼ cup sweet chili sauce and cook for a few minutes until the sauce bubbles and thickens.
5: Turn off the heat and add the chicken back into the sauce. Toss well to coat the chicken.
