Tips
When rinsing chicken, hold it as close to the bottom of the sink as possible and use a gentle stream of water to avoid splashing.
Wash your sink and counters immediately after rinsing chicken.
Be sure you give your skillet plenty of time to preheat so the oil is nice and hot and the chicken immediately begins to crisp.
