Add half of the wings to the batter. Working one at a time, lift one wing and allow excess batter to drip off, using your finger to get rid of any large pockets or slicks of batter. Carefully lower wing into hot oil. Repeat with remaining wings in first batch. Fry, using a metal spider or slotted spatula to rotate and agitate wings as they cook until evenly golden brown and crisp all over, about 8 minutes. Transfer to a paper towel-lined plate and season immediately with salt. Keep warm while you fry the remaining wings.
