For the brine:
1/3 cup granulated sugar
1/3 cup kosher salt
1 bay leaf
1 tsp red pepper flakes
1 tsp ginger paste
Peel of 1 orange
For the chicken:
2kg chicken portions
2 cups all-purpose flour
1/4 cup cornmeal
1/4 cup crushed potato chips
2 tsp onion powder
1 tsp espelette pepper
2 tsp cracked black pepper
1 tsp cumin powder
1 tsp paprika powder
1 tsp ginger powder
2 tsp salt
500g buttermilk (can be substituted by plain yogurt)
For the brine:
Fill a large pot with 5 cups of water. Place the pot over high heat and bring to a boil. Add the sugar, salt, bay leaf, red pepper flakes, ginger and orange peel. Cook, stirring, until the sugar and salt dissolve, about 1 minute. Remove from the heat and let cool.
Place the chicken in a large bowl and cover completely with the cooled brine. Cover and refrigerate for 10 to 12 hours, and up to 24 hours.
Remove the chicken from the brine and pat dry with a paper towel. Set the chicken aside and discard the brine.
For the chicken:
To batter the chicken: In a large bowl, stir together the flour, cornmeal, crushed potato chips, and spices until combined. Transfer to a large shallow dish. Place another large shallow dish next to the flour mixture and add the yogurt to it. Place a wire rack or pan next to the two dishes; this will be where you set your battered chicken.
Take one piece of chicken and submerge it in the buttermilk. Lift and let any excess drip back into the dish. Roll it in the flour mixture, coating it completely. Place the battered chicken portion on the wire rack or pan and repeat with the remaining chicken.
Let the chicken dry for 20 to 30 minutes before frying.
To fry the chicken: In a large Dutch oven over medium heat or deep fryer, heat the canola oil to 350F/180C. Place a wire rack over a plate or line a pan with brown paper and set aside.
Working in batches, fry 3-4 pieces of chicken for 13-15 minutes (until internal temp if 165F/75C).
If the chicken is getting too dark, lower the heat. Once the chicken is done, remove each piece with tongs and transfer to the prepared rack or pan to drain. Sprinkle generously with salt.
