Louisiana Fried Chicken
Place chicken in large, glass bowl or dish; pour buttermilk over it. Cover and refrigerate for 30 minutes.
In medium bowl, whisk together flour, cornmeal, salt, celery salt, pepper, paprika and cayenne. Dredge chicken pieces in flour, two at a time, turning to coat all sides thoroughly. Set chicken on a rack and let sit for 30 minutes.
In large, cast iron skillet add oil to fill ¾ inch (2 cm) deep. Over medium-high heat, warm oil to 350°F (175°C), using a kitchen thermometer to test oil temperature. Carefully place chicken, skin-side-down in oil. Reduce heat to medium and cook chicken for 15 minutes until nicely browned. Turn chicken and cook for additional 10 minutes, until internal temperature registers 165°F (74°C) on thermometer. Remove chicken and drain on paper towels. Cook remaining chicken in same manner until done. Before serving, reheat sauce and pass separately.
