Cut the chicken in half lengthways to give 4 thinner fillets. Coat each piece in cornflour.
Heat some cooking oil in a large frying pan over a medium-high heat. Cook the chicken breasts until they are golden brown on both sides.
Meanwhile, in a bowl, add the soy sauce, sesame oil, mirin, honey, garlic paste, ginger paste, and gochujang. Mix it well.
Pour it over the chicken and continue to cook until it’s bubbly and sticky.
Dish it up with rice, and sprinkle over some sesame seeds and sliced spring onions.
