Kentucky Fried Chicken in their bucket.
The High-Tech Fryer KFC Uses For Chicken And How To Replicate It Yourself
By Chase Shustack
KFC is in possession of multiple industrial-strength pressure fryers that can quickly crispen the skin of any piece of chicken put in them.
KFC uses the "Collectramatic Fryer" and "CVap Holding Cabinets" models from Winston Foodservice, but there is a way to get similar results at home.
A simple method is to fill your deep fryer (a Dutch oven or any heavy pot will also work just fine) with oil, heated to 350 to 360 degrees.
Add your chicken pieces, leaving each piece in for around 12 minutes before removing to drain on paper towels.
Let your chicken cool off for a few minutes, or finish baking the chicken in a 175-degree oven for 20 minutes before serving to keep the skin crispy.
