Crisp wings without a deep fryer come down to drying them thoroughly and a light dusting of baking powder before they go in a hot oven — that combination is what blisters the skin. Chef Emily explained why it works rather than just instructing, and mine came out genuinely crisp, which I'd never managed at home. The sauce is butter and hot sauce emulsified together, and adding the butter off the heat is what stops it splitting.
