Start by trimming excess fat and patting the chicken dry. This ensures the coating sticks and stays crispy during frying. Season lightly with salt and pepper.
In a shallow bowl, combine cornstarch, flour, and a pinch of salt. In a separate bowl, beat the eggs. Dip each chicken piece in egg, then dredge in the flour mixture evenly.
Heat oil over medium-high heat and fry chicken until golden brown and cooked through. About 4–5 minutes per side depending on thickness. Transfer to paper towels to drain.
Whisk together mayonnaise, sweet chili sauce, sriracha, honey, and garlic powder. Taste and adjust spice or sweetness as you like.
Slice chicken into strips or bite-sized pieces. Toss gently in the sauce until coated evenly. Serve immediately for best crispiness.
