Place the chicken in a medium-sized bowl. Cover with buttermilk. Stir in the hot sauce, garlic powder, and salt. Cover with plastic wrap and keep in the fridge for at least one hour, or even better, overnight.
2 cups buttermilk, 2 tbsp hot sauce, 2 tsp garlic powder, 2 tsp Kosher salt
Prep the Flour Mixture and Chicken for Frying
Heat oil in a large sturdy skillet to 340°F to 350°F.
In a medium-sized bowl or dish, stir together the flour, cornstarch, garlic powder, chili powder, salt, and pepper. Add 5 tablespoons of the chicken marinade to the flour mixture and gently stir until incorporated. There should be clumps that have formed from the marinade in the flour.
1½ cups all-purpose flour, 1 tbsp cornstarch, 1 tsp garlic powder, 2 tsp chili powder, 1½ tsp Kosher salt, ½ tsp black pepper
Work one chicken thigh at a time, remove it from the marinade, and shake off the excess. Place the thigh in the flour mixture and turn it several times to fully coat the chicken. Place on a baking rack on a baking sheet and continue with the remaining chicken thighs.
Working in batches, carefully place the breaded cutlets into the hot oil. Don't overcrowd the pan! Cook until golden brown and very crispy, using metal tongs to carefully flip the cutlets occasionally until the internal temperature reaches 165°F, about 8 to 10 minutes. Remove from the oil and place on a baking sheet over a baking pan. Repeat with remaining cutlets.

Build the Sandwich
Toast the buns until lightly browned. Add a thin layer of the remoulade on the bottom bun of all sandwiches. Next, place a fried chicken cutlet on the prepared bun. Top with pickles and then the top bun. Serve at once.

Notes
NOTE: Watch the video in the recipe card for visual guidance.Chicken breasts can be used in place of the thighs. If large chicken breasts, cut them in half, lengthwise, before breading them. Adding the marinade to the flour mixture isn't an exact science. You want to add enough so that small clumps form throughout the mixture when stirred. Usually, 5 tablespoon is just enough, but feel free to add more if desired. Just don't add so much that it makes the flour mixture become wet. Extra fried chicken fillets can be reheated and crisped up in a 350°F oven on a baking rack on a baking sheet for 20 minutes.
