The secret to juicy buttermilk fried chicken with a craggy crust lies in a proper buttermilk marinade, a seasoned flour dredge with cornstarch or baking powder, and maintaining the correct oil temperature during frying.
Achieving perfectly fried chicken requires a multi-step process focused on moisture retention and crust development. Here's a breakdown:
Buttermilk Marinade: Buttermilk tenderizes the chicken and adds moisture. Marinate the chicken pieces for at least 4 hours, or preferably overnight, in buttermilk seasoned with salt, pepper, garlic powder, and onion powder. The acidity in the buttermilk helps break down the proteins, resulting in a more tender and juicy interior.
Double Dredge: The dredge is crucial for the crust. Use a mixture of all-purpose flour, cornstarch (or baking powder), and your favorite seasonings (paprika, cayenne pepper, garlic powder, onion powder, dried herbs). Cornstarch helps create a lighter, crispier crust, while baking powder adds lift and airiness. A double dredge involves coating the chicken in the flour mixture, then dipping it back into the buttermilk, and then coating it again in the flour mixture. This creates a thicker, craggier crust.
Oil Temperature: Maintain a consistent oil temperature of around 325°F (163°C). If the oil is too hot, the outside will burn before the inside is cooked. If it's too cold, the chicken will absorb too much oil and become greasy. Use a deep-fry thermometer to monitor the temperature. Fry in batches to avoid overcrowding the pot and lowering the oil temperature.
Resting: After frying, place the chicken on a wire rack to drain excess oil. This allows the crust to stay crispy instead of becoming soggy from sitting in its own oil.
Don't overcrowd the frying pan! Frying in batches ensures the oil temperature remains consistent, leading to evenly cooked and crispy chicken. Overcrowding lowers the oil temperature, resulting in soggy, greasy chicken.
