1/2 cup gochujang sauce* (Korean hot pepper paste)
1/4 cup light soy sauce
1/4 cup rice vinegar
1/4 cup brown sugar
3 tbsp sesame oil
5 garlic cloves, crushed
5cm piece fresh ginger, finely grated
Green onions, thinly sliced, kimchi, and sweet potato chips, to serve
Method
Place the salt and 1 litre of warm water in a large bowl and swirl to dissolve the salt. Add the chicken pieces to the brine. Cover and refrigerate for 4 hours (or up to 12 hours.) Take the chicken out of the brine and dry with paper towels. Lay out to allow the skin to continue drying
Pour the oil into a large heavy-bottomed saucepan or deep-fryer and set over medium heat. Attach a deep fry thermometer if you have one. Mix 3/4 cup of corn flour and 2 teaspoons of baking powder in a bowl. Add the chicken to the bowl and toss to coat well. Place the remaining 1/2 cup of corn flour, 1 teaspoon baking powder, and 3/4 cup of flour in a separate bowl. Whisk in the club soda or beer to create the tempura batter
Preheat the oven to warm (90°C) and line a baking tray with paper towels. Heat the canola oil in a deep fryer or large heavy bottomed saucepan to 180°C. Drop a little batter into the oil to check. If the batter turns brown right away the oil is too hot. Turn off the heat and wait for it to cool before continuing. One piece at a time, tap the excess corn flour off the chicken and dip it in the tempura batter. Coat a couple of times to make ensure there are no air pockets. Shake the chicken a little to allow the excess batter to drip back into the bowl then slowly swirl the chicken as you place it in the oil. Fry 2 to 3 pieces at a time, until golden brown and crispy. Turn the chicken as required. The wings should be golden and cooked through in around 10 minutes, and the drumsticks and thigh portions will take between 12-15 minutes, depending on the size
Using tongs put the chicken on the prepared baking tray and place in the oven while you cook the remaining chicken - this will take 2-3 batches
While the chicken is frying, place the remaining ingredients for the Korean dunking sauce in a medium saucepan over medium heat, stir, and bring to a boil. Once the sauce is boiling, reduce heat to low and simmer for 2 minutes. Remove from heat and check for spice
To serve, drizzle each piece of chicken with the sauce. Sprinkle with green onions and serve with kimchi and sweet potato fries
