Method
Mix all seasoning ingredients thoroughly.
Stir 3 tablespoons of the seasoning mix into the buttermilk.
Add chicken and refrigerate 4–24 hours.
Mix all-purpose flour, rice flour, baking powder, and the remaining seasoning mix.
Drizzle 1 cup of the buttermilk into the flour mixture and toss to form small clumps (pebbles).
Heat oil to 300°F (150°C).
One piece at a time, remove chicken from buttermilk, dredge in flour mixture, press firmly, shake off excess.
Fry until they float and reach 185°F internal temperature.
Transfer to a wire rack and salt immediately while hot.
