It's pretty straight forward. Salt and pepper your chicken in a large bowl, pour buttermilk over the chicken and let rest in the fridge overnight. In another large bowl, pour in your flour and add salt, pepper, smoked paprika, cayenne pepper and a touch of garlic powder. Amounts will vary based on what you like. I put about a 3/4" to 1" of oil in my cast iron skillet and turn to medium/medium-high heat. I recommend either vegetable shortening or peanut oil but really, just pick an oil that has a nice, high smoke point. Once the oil is good and heated, I pull the chicken out of the buttermilk and toss them into the flour mix. Ensure that the chicken is nice and covered with your flour mix and then into the pan they go for roughly 25 to 30 minutes (time varies with the size of the individual chicken pieces). Make sure your rotate every so often to avoid burning one side. If your temps are getting high, turn down the temperature and add a touch of room temperature oil.
