In a large resealable bag or 9x13-inch dish, combine the chicken pieces, buttermilk, and salt.
4 bone-in, skin-on chicken thigh, 4 chicken drumstick, 4 cup buttermilk, 1 teaspoon salt
Toss gently to coat, then cover and refrigerate for at least two hours or up to six hours.
Line two sheet trays with wire racks. Top one of the racks with paper towels for draining.
Preheat the oven to 300°F (165°C). This step is optional for finishing the chicken, if needed.
In a large bowl, whisk together all the dredge ingredients and spices.
2 teaspoon sweet paprika, 2 teaspoon garlic powder, 2 teaspoon onion powder, 1 teaspoon black pepper, 1 teaspoon chicken bouillon powder, 1 teaspoon dry mustard, 1 teaspoon dried thyme, ½ teaspoon smoked paprika, 1 teaspoon kosher salt, 2 cup all-purpose flour, 2 tablespoon cornstarch, 1 tablespoon baking powder
Spoon a few tablespoons of the buttermilk marinade into the flour mixture, and use fingertips to rub it in, creating craggly bits for extra crunch.
Working one at a time, lift the chicken pieces from the marinade, allowing the excess to drip off.
Firmly press each piece into the flour mixture, flipping and pressing to coat fully.
Transfer the breaded chicken to the clean wire rack.
In a Dutch oven or heavy-bottomed pot, add about three inches of oil, and heat to 325°F (163°C).
vegetable or peanut oil
Working in batches, fry two to four pieces of chicken at a time, making sure not to overcrowd the pot.
Maintain the oil temperature at 325°F (163°C), and fry until the chicken reaches an internal temperature of 170°F (77°C). If the outside is browning too quickly before the chicken is fully cooked, transfer it to the paper towel-lined rack and place it in the preheated oven to finish cooking.
Let the chicken cool slightly, allowing the crust to set.
Serve warm with any desired dips and sauces.
