Copper metal that is required to maintain its color may be treated with an organic coating. Single-strand copper wire for electrical purposes does not usually tarnish enough to warrant special treatment. However, fine, multistranded copper wire is usually wrapped with layers of insulating materials. If the wire is kept wrapped, oxidation is quite low, and its color is maintained.
Put the wings in a single layer on the grill over the heat. Cook the wings for about 20-25 minutes total. Start by leaving them on there, lid closed, for a few minutes. Then use big tongs to have look underneath them all.
Bake the wings for 30 minutes. After the first 30 minutes pass, baste the wings using another 1/4 cup (60 mL) of the same sauce before returning them to the oven. The oven must be completely preheated before you can begin cooking the wings.
