Glazed Fried Chicken With Old Bay and Cayenne

Heat salt, brown sugar, and 4 cups water in a large pot over medium, whisking, until salt and sugar dissolve, about 5 minutes. Remove from heat and stir in hot sauce and 8 cups ice water. Add chicken to brine, cover, and chill 4 hours. Combine 2 cups flour and 3 tablespoons Old Bay seasoning in a shallow baking dish and toss with your fingers to evenly distribute seasoning. Place buttermilk in a medium bowl. Remove chicken from brine and pat dry with paper towels. Working one at a time, dip 8 pieces of chicken in buttermilk, allowing excess to drip off, then coat in flour mixture, packing all around chicken and pressing firmly into cracks and crevices; shake off excess. Place chicken on a wire rack set inside a rimmed baking sheet. Discard flour mixture, which will be wet at this point, and repeat process with remaining flour, Old Bay, buttermilk, and chicken; place on another wire rack set inside a rimmed baking sheet. Chill, uncovered, 12 –24 hours.
