Cooking the chicken on a cooling rack allows the dry heat to crisp both sides, but if you don’t have one, simply coat a parchment or foil-lined cookie sheet with cooking spray, and turn the chicken pieces over after ten minutes. In place of cooking spray, I use a bit of olive oil in a spray-pump or mister. If you don’t have this, fear not, they will still turn out fine. Makes about 2 dozen nuggets
