Trim the excess skin and fat from chicken thigh or wing. Place the thighs or wings in a baking dish just big enough to accomodate the chicken. If you have too much space between the pieces the sugars in the sauce will burn and your evening’s entertainment will consist of dish scrubbing.
Whisk together the soy sauce, brown sugar, onion and garlic, Pour the sauce over the chicken. Turn each piece so it is well coated and then leave it skin side up.
