Dry the chicken wings well on paper towels.
Once chicken wings are dried, season well with salt and pepper.
In a medium-large mixing bowl, toss the seasoned chicken wings to coat in cornstarch.
Heat about 3” of oil over medium-high heat in a medium sauce pan or deep pot.
Leave oil to get hot for about 7-10 minutes. To test if oil is ready, sprinkle a tiny bit of cornstarch into the oil. If the cornstarch dissipates immediately, the oil is ready. If it lingers or floats, give the oil a few more minutes and test again. You want it to sizzle on contact.
Once the oil is ready, fry the wings. Working in batches, fry flats first.
Fry the wings for 6 minutes, and transfer to a wire rack lined baking sheet to drain. While the wings drain, Fry the second batch of wings (drums) for 6 minutes. Remove second batch of wings to rack lined sheet, and add previously fried first batch back to the hot oil.
Fry the wings for an additional 4 minutes, then drain again. Repeat with second batch of wings, until all wings are double fried.
Sauce immediately after cooking in a large bowl, tossing to coat.
