Place the chicken wings in a plastic bag. In a small bowl, mix together the baking powder, baking soda, and salt.

Pour the baking powder mixture into the bag with the chicken wings. Shake the bag very well to ensure that the wings are completely coated in the mixture.

Place the chicken wings on a wire rack and leave in the fridge overnight. This helps dry them out and breaks down the peptide bonds in the proteins of the chicken to give a crispier end result.

The next day, place a baking tray with a rack in the upper-middle part of the oven and preheat it to 450F. Once heated, place the chicken wings on the rack and bake for 20 minutes.

Remove from the oven and flip over. Bake for another 15 minutes or until very crisp.

Toss with melted butter. Serve and enjoy!
