Rinse fish and cut in half.
Mix all dry ingredients in a bowl.
Pour oil in pan and turn heat on medium.
Mix the buttermilk and egg in a separate bowl from the dry ingredients.
Dip filets one at a time in the egg mix and then the dry mix. Set aside each one as you're done coating them.
Make sure the oil is at 350°F and then slowly put the fillets in the pan. I can fit 4 in my pan without overlapping.
