A good copycat recipe for Popeye's fried chicken requires buttermilk, flour, cayenne and black pepper, and paprika. This recipe also includes instructions for making the accompanying Popeye's Delta Sauce.
To make Popeye's fried chicken, cut 1 chicken into pieces and cover in 1 quart buttermilk. Refrigerate, covered, for at least 2 hours. Add 4 cups flour, 3 tablespoon cayenne pepper, 2 teaspoons black pepper, and 2 teaspoons paprika to a gallon zip bag and shake to combine. Mix 3 eggs, 1/3 cup water, and 1 cup hot sauce in a separate bowl. Remove chicken from buttermilk and place on cooling rack to allow buttermilk to drip off. Place 3 cups peanut oil in a saucepan and heat until oil is 350 degrees Fahrenheit. Drop chicken pieces into the dry ingredient bag and shake to cover; dip them in egg mixture and coat again in the dry ingredient bag. Put chicken back on the rack to allow extra coating to drip. Lower a few pieces of chicken at a time into oil and cook about 15 minutes, maintaining oil temperature at 350 degrees. Serve immediately.
To make Delta Sauce, combine 1/2 cup mayonnaise, 1 clove minced garlic, 1 tablespoon lemon juice, 1/4 cup vegetable oil, 1/4 cup chili sauce and 1/4 cup ketchup; furthermore, add 1 teaspoon onion powder, 1 teaspoon Worcestershire, 1/2 teaspoon paprika, 1/2 teaspoon fresh black pepper, 1/2 teaspoon mustard and hot sauce to taste. Mix well and chill at least 1 hour before serving.
