“There’s nothing not to like about this ubiquitous Korean fried chicken dish, coated in a slick of smoky ‘gochujang’ chilli paste, roasted sesame oil, garlic, ginger and vinegar – it’s totally addictive. This is a great dish to scale up and make for a crowd; simply prepare the sauce and fry the chicken wings once in advance, then a second time just before you are ready to serve.
For the sauce, peel and crush the garlic, peel and very finely grate the ginger and add to a pan with the remaining ingredients. Place over a medium-high heat until beginning to bubble; reduce the heat and cook, stirring, for 10 minutes, or until thickened and syrupy. Remove from the heat and set aside.
Prepare your deep-fat fryer if you have one. Otherwise, pour the vegetable oil into a large pot, to no higher than 5cm below the rim, and use a thermometer. Place over a medium-high heat and, using a thermometer to guide you, bring the oil to 150ºC.
Meanwhile, combine the flours, baking powder, 1 teaspoon of black pepper and 2 teaspoons of sea salt in a bowl. Add the chicken, toss to coat, then gently shake off any excess. Once the oil is hot, add the chicken and cook, in batches, for 12 minutes. Remove and drain on kitchen paper.
Increase the temperature of the oil to 185ºC. Return the chicken to the oil, in batches again, and fry for 6 more minutes, until golden brown and crispy. Remove and drain as before.
Reheat the sauce, if necessary, then gently toss with the chicken to coat completely. Serve the sticky wings piled up with the sesame seeds and thinly sliced chives scattered over.
