If you like fried chicken this one is excellent and well worth the time to make! The chicken has to marinate in the buttermilk so you can start it a day or two ahead. this recipe comes from Bon Appetit, 1998.
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.

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.
