Deviled Fried Chicken

Preparation In 1-gallon resealable plastic bag, mix buttermilk, Dijon mustard, 1 tablespoon onion powder, 1 teaspoon salt, 1 teaspoon dry mustard, 1 teaspoon cayenne and 1 teaspoon black pepper. Add chicken pieces. Seal bag, eliminating air. Turn bag to coat chicken evenly. Refrigerate at least 1 day and up to 2 days, turning plastic bag occasionally. Whisk flour, baking powder, garlic powder, remaining 1 tablespoon onion powder, 4 teaspoons salt, 3 teaspoons dry mustard, 3 teaspoons cayenne and 1 1/2 teaspoons black pepper in 13 x 9 x 2-inch glass dish. With marinade still clinging to chicken pieces (do not shake off excess), add chicken to flour mixture; turn to coat thickly. Let chicken stand in flour mixture for 1 hour, turning chicken occasionally to recoat with flour mixture. Pour oil to depth of 1 1/4 inches into deep 10- to 11-inch-diameter pot. Attach deep-fry thermometer. Heat oil over medium-high heat to 350°F. Add 4 pieces of chicken, skinned side down, to oil. Reduce heat to medium-low and fry 5 minutes, adjusting heat to maintain oil temperature between 280°F and 300°F (oil should bubble constantly around chicken). Using wooden spoons, turn chicken over. Fry 7 minutes. Turn chicken over again. Fry until deep golden brown and cooked through, about 3 minutes longer. Using same spoons, transfer chicken to large rack set on baking sheet. Reheat oil to 350°F. Repeat frying with remaining 4 pieces of chicken. Serve chicken warm or at room temperature within 2 hours, or chill up to 1 day and serve cold.
