Step 1

Combine buttermilk, sugar and 1 tbsp salt in a large bowl, and stir well. Add chicken thighs, making sure they’re covered and refrigerate to marinate (at least 4 hours or overnight).

Step 2

Combine flours in a large bowl and season to taste. Drain chicken from buttermilk and toss in flour mixture to coat well.

Step 3

Heat oil in a deep-fryer or deep saucepan to 160C. Shake off excess flour from chicken and deep-fry, turning occasionally, until golden and cooked through (5-7 minutes; be careful as hot oil will spit). Drain chicken on paper towels.

Step 4

Spread a generous amount of mayonnaise on the bottom half of each burger bun, then top with tomato slices, lettuce, pickles, chicken, then a slice of cheese. To finish, spread your sauce of choice on the top half of each bun and place on top. Serve with crisps or hot chips.
