In a large pot, heat 2 inches of oil to 350° over moderately high heat. In a large resealable plastic bag, combine the flour and cornstarch and season well with salt and pepper. Add the wings to the bag; shake well to coat. Transfer the wings to a strainer set over a bowl; shake to remove any excess flour. Fry the wings, in batches if necessary, until golden and crisp, about 12 minutes. Drain on paper towels.
