Delicious Chick-fil-A style chicken biscuits made with marinated chicken thighs and homemade biscuits. Marinate chicken thighs in a mixture of buttermilk, pickle juice, and hot sauce for tenderness. For the biscuits, combine flour, sugar, baking powder, and salt, then fold in cold butter and buttermilk. Bake until golden brown and serve with crispy fried chicken.
