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.
Preheat oven to 250Â°F. Place a rack onto a cookie sheet. In a large bowl, toss the flats and drumettes with the baking powder and salt. Place wings on the rack in single layer and cook for 30 minutes. After 30 minutes, leave them in there and raise the heat to 425Â°F until brown and crispy, 40-50 minutes.
