Place the chicken breasts between two pieces of heavy-duty plastic wrap and gently pound them to about 1/4-inch thick using the FLAT side of a meat mallet. Combine 1/2 teaspoon salt and 1/2 teaspoon black pepper in a small bowl, then season both sides of the chicken with the mixture. Set aside.
8 (6-ounce) boneless, skinless chicken breasts, 4 1/2 teaspoons Kosher salt, 2 1/2 teaspoons black pepper
In a shallow dish, stir together the cracker crumbs, 2 cups of the flour, baking powder, 1 1/2 teaspoons of the salt, 1 teaspoon of the black pepper, and cayenne. In a separate bowl, beat the eggs with 1 1/2 cups of the milk until smooth.
4 1/2 teaspoons Kosher salt, 2 1/2 teaspoons black pepper, 2 sleeves Saltine crackers, 2 1/2 cups all purpose flour, 1 teaspoon baking powder, 1 teaspoon cayenne pepper, 8 cups whole milk, 4 large eggs
Coat each piece of chicken in the cracker mixture, dip it in the milk and egg mixture, then return it to the cracker crumbs for a second, extra-crunchy layer.
Add 1/2 inch of oil to a large skillet and heat to 360°F (182°C). Fry the chicken in batches for 10 minutes, adding more oil if needed. Flip and cook another 4 to 5 minutes until crisp and golden. Transfer to the prepared wire rack set over a baking sheet and keep warm in your preheated oven. Carefully pour off the oil, saving 2 tablespoons of drippings and all those flavorful browned bits in the pan.

In a bowl, whisk the remaining 1/2 cup flour with 2 1/2 teaspoons salt, 1 teaspoon black pepper, and 6 1/2 cups milk. Pour into the skillet with the reserved drippings and cook over medium-high heat, whisking constantly, for 10 to 12 minutes until thick and creamy. Spoon that rich gravy generously over the chicken and serve.
