If you are using my Salt Free Smoky Barbecue Chicken Rub, mix it with the salt. If you are using another chicken rub, it probably already has salt in it, so you can skip adding more salt.
Add the baking powder to the rub mixture.
If you want the chicken wings a bit more spicy, add the red pepper flakes, and mix thoroughly .
Seasoning the wings
Put the wings in a large work bowl, and pour the seasoning mixture over. Mix everything together until all the wings are evenly coated, and there are no clumps of seasoning remaining.
Take a large baking sheet, and line it with foil. (This will make it much easier to clean.)
Place a wire rack over the foil lined baking sheet, and spread the wings out, trying to leave some space between each wing if possible.
Place the wings in the fridge, and allow to rest for at least an hour, up to a day. The longer the better.
Cooking the wings
Pre-heat oven to 425°F.
Place the tray of wings in the oven.
Flip the wings after 20 minutes, and continue cooking.
Flip the wings again after another 20 minutes, and continue cooking.
After ten more minutes, flip the wings again, and continue to cook for a final 10 minutes.
