Prep your chicken by trimming it into less than a 1/2" patties for frying.
Prepare your batter and flour in two separate bowls.
Dunk your chicken into the flour, then batter and then flour again. While your chicken is sitting with the battered flour pour 2 1/2 cups of cooking oil into your pan over medium heat or 350 degrees. Let it come to temp, about 20 mins.
Once your oil has reached the temp of 350, go ahead and fry 3-4 pieces of chicken at one time. You are going to fry for 7 mins (flipping at the midway point) and then pull the chicken and let sit for 5 mins then refry for the second time 3 mins, this depends on the thickness of the chicken.
Now that your chicken is fried make sure you have a wire rack with a sheet pan under it so the crispy chicken can sit and rest on. During this resting time, you are going to add your Nashville Hot Chicken seasoning together with 1 1/2 cups of the cooking oil you just used. It will simmer but quickly whisk until it comes still. Now you want to brush that amazing sauce all over the crispy chicken or dunk it.
Have some toasted buns ready and create your sandwich. First, you want to sauce your top and bottom buns, add shredded romaine lettuce, chicken patty, tomato and then complete with the top bun for an amazingly delicious creation.
Feed the family and enjoy! This one gets spicy :)
