For the flour mix: Combine all the ingredients in a bowl.
1 1/2 cups plain flour, 1/4 cup cornflour, 1 teaspoon paprika, 1 teaspoon garlic powder, 1 teaspoon white pepper, 1 teaspoon onion powder, 1 teaspoon sea salt
Place one chicken piece at a time in the buttermilk mix and completely saturate it. Lift it out, let it drip over the bowl and carry it over to the flour bowl, making sure you cover it well. Place on a plate, ready to be fried. Continue with the remaining chicken pieces.
6 chicken thighs
Preheat a deep frying pan or cast iron pan over high heat and add enough oil to come one-third up the side of the pan. Heat the oil to 180°C (if you don’t have a thermometer, test by throwing in a little of the chicken coating – if it bubbles, it’s ready).
vegetable oil
Place the chicken pieces in the hot oil and cook for 3–4 minutes on one side, then use tongs to flip and cook for 2–3 minutes on the other side, or until the coating is golden and bubbly. Be careful the oil doesn’t get too hot or the batter will burn and come away from the chicken. Keep an eye on it and turn it down if it’s colouring too much. Remove the chicken and drain on paper towel.
Add some sweet chilli mayo to the brioche rolls. Top with the buttermilk chicken, coleslaw and lettuce. YUM!
