in the kitchenthe baking powder bake

The home method that gets wing skin to crisp in an oven: toss dried wings with baking powder and salt, bake low to render and dry, then hot to brown. No fryer, no pot of oil, and a crust that holds sauce for about as long as it takes to eat.

The trick is a pH trick. Baking powder is alkaline — the opposite of acidic — so, as Christine Pittman of TheCookful puts it, "The addition of the baking powder therefore raises the pH level in the chicken, allowing the peptide bonds in the skin to break down, which in turn lets the skin get more crisp and brown." Nagi Maehashi of RecipeTin Eats describes the same result by a different mechanism: "the baking powder draws moisture to the surface of the skin so it can evaporate, thereby making the skin crispier."

The method arrived with the appliance. Convection — a fan moving air around the food to heat it evenly — was already in home ovens, and small countertop convection ovens are now marketed as air fryers; US household ownership was reported at 36% in 2020 and estimated at 60% in 2023.

Inference — this is the version of the wing most Americans actually cook. The fryer belongs to the bar; the oven belongs to the house, and the baking powder is what closes the gap between them.

Dry the wings thoroughly. Toss with baking powder and salt — RecipeTin Eats uses 5 teaspoons of baking powder and 3/4 teaspoon of salt for 4 lb / 2 kg of wings. Rack over a tray so air reaches underneath. Bake low first, 120 °C / 250 °F for 30 minutes, to render fat and dry the skin, then raise to 220 °C / 425 °F for 40–50 minutes to cook through and brown. Sauce after the oven. Use baking powder, not baking soda; RecipeTin Eats warns in capitals that readers who have swapped them found the result "INEDIBLE".

The standard home recipe across American food sites, and the method most often reached for on Super Bowl Sunday, the second-largest American eating day after Thanksgiving. Inference — the recipes agree on the ratio and the two temperatures and disagree on the chemistry, which suggests the method was found by cooking rather than by explanation.
