Step 1: Marinate the Chicken:
In a large bowl, whisk together the buttermilk, hot sauce, 1 teaspoon of salt, and black pepper. Add the chicken pieces, ensuring they are fully submerged in the marinade. Cover the bowl with plastic wrap and refrigerate for at least 4 hours, or preferably overnight. The longer the chicken marinates, the more flavorful and tender it becomes.
Step 2: Prepare the Spice Blend:
In a separate large bowl, combine the flour, cornstarch, paprika, garlic powder, onion powder, cayenne pepper, dried oregano, dried thyme, cumin, and remaining 1 teaspoon of salt. Whisk the ingredients together thoroughly to ensure the spices are evenly distributed. This mixture creates the crispy and flavorful coating.
Step 3: Bread the Chicken:
Remove the chicken pieces from the buttermilk marinade, allowing any excess to drip off. Dredge each piece in the spice blend, pressing firmly to ensure the flour adheres to all surfaces. For a thicker coating, double-dredge the chicken by dipping it back into the buttermilk and then again into the spice blend. Place the breaded chicken on a wire rack to rest for 15-20 minutes.
Step 4: Heat the Oil:
Pour vegetable oil into a large, heavy-bottomed pot or deep fryer until it reaches a depth of about 3 inches. Heat the oil over medium-high heat to 325-350F (160-175C). Use a thermometer to monitor the oil temperature and adjust the heat as needed to maintain a consistent temperature.
Step 5: Fry the Chicken:
Carefully place the breaded chicken pieces into the hot oil, ensuring not to overcrowd the pot. Overcrowding can lower the oil temperature and result in greasy chicken. Fry the chicken for about 6-8 minutes per side, or until the internal temperature reaches 165F (74C) and the crust is golden brown and crispy. Use tongs to turn the chicken pieces occasionally for even cooking.
Step 6: Drain and Serve:
Remove the fried chicken from the oil and place it on a wire rack lined with paper towels to drain excess oil. Allow the chicken to cool slightly before serving. Serve immediately and enjoy.
Optional tips: For extra flavor, add 1 tablespoon of your favorite Cajun seasoning to the spice blend. If you don't have buttermilk, you can make a substitute by adding 1 tablespoon of white vinegar or lemon juice to 2 cups of milk and letting it sit for 5 minutes. Adjust the amount of cayenne pepper to control the spiciness of the chicken.
