In a large resealable plastic bag, combine the flour, garlic powder, garlic salt, mustard, ginger, nutmeg, pepper, allspice and cayenne.
Cut chicken wings into three sections; discard wing tip sections. Dip chicken in butter, then add chicken wings, a few at a time, to flour mixture and toss to coat.
Arrange wings in a single layer in an ungreased 15x10x1-in. baking pan. Bake, uncovered, at 400° for 35-40 minutes or until chicken juices run clear. Broil 3-4 in. from the heat for 4-6 minutes or until golden brown.
