good way to make wings

Baked wings in the oven last night.  They turned out really good!  I baked them on wire racks at 250 for 30 minutes and then upped it to 425 for another 45 minutes. Before the baking the only thing i had put on them is baking powder.  I put 1 tablespoon for 20 wings.  I sprinkled on the wings and used my hands to rub it in.
After they baked i tossed them in the sauce.  The wire rack/baking powder method is what made them so good and crispy!!
