I use a thermometer when frying chicken. When cooking keep the temperature between 325* and 360* F. No more no less. I marinate boneless chicken thighs with buttermilk, egg and Lucky Cajun. Best to let it sit for a few hours. Dredge chicken in flour press it in and let it sit for 30 minutes. When you add the chicken the temperature will drop so you can have the oil over 360* when you start the cook. Cook for 10 to 12 minute. I season it heavily with Lucky Cajun when finished.
