Preheat oven to 250°F. Line a large baking sheet (half sheet pan size works) with foil. Place a cooling wire rack on top and spray surface with cooking oil spray.

In a large bowl, add wings and sprinkle with salt and baking powder. Toss the wings until they are evenly coated in the baking powder and salt.

Place the wings, side by side onto the cooling rack. All the wings should fit in a single layer on baking sheet without touching (but they will be quite close to each other).

Bake for 30 minutes in the lower half of the oven. The wings should look smaller (from the skin being dried out and fat rendered off) but still very pale.

Raise oven temperature to 425°F. Place wings back into the oven, this time in the upper middle section of the oven. Bake wings for about 50 minutes. Wings should be golden brown and when you touch the skin, it should feel crispy. Allow the wings to cool for about 5-10 minutes, which should further settle and crisp the skin even more. Eat wings as is or coat them in your favorite glaze or serve them with your favorite dipping sauce.
