Place chicken pieces on a baking sheet. Sprinkle on both sides with the 1 tablespoon of salt and 1 teaspoon black pepper. Let sit at room temperature while you heat the oil.
Attach a deep fry thermometer to the side of a deep cast iron pot or Dutch oven. Pour in enough oil so it reaches 2-inches up the side of the pot (I used 2 liters of oil but this will depend on the size of your pot). Heat oil over medium-high heat to 350°F or until a piece of bread browns immediately when dropped in the oil. This usually takes between 10-15 minutes to reach temperature. Once it reaches temperature continue turning heat up or down to maintain 350°F.
While oil is heating, place flour in a shallow dish and season with remaining 1 teaspoon salt and 1/2 teaspoon black pepper; stir to combine. Heat oven to 250°F, cover a baking sheet with paper towels and set a wire rack on top.
Once oil is hot, coat a few pieces of chicken in flour, massaging it into the nooks and crannies. Fry 3 to 4 pieces at a time, flipping occasionally, until crispy, brown, juices run clear, and an instant read thermometer stuck in the thickest part of the chicken reads 170°-175°F about 12-15 minutes. Place on the wire rack and transfer to the warm oven. Continue with remaining chicken.
Let final pieces of chicken rest 10 minutes before serving. Then serve with hot sauce.
