Put the chicken in a bowl and grate half an inch of ginger and 1 clove of garlic over it. Knead together. Put the sunflower oil in a pan or frying pan and heat to 180˚C. You can tell if the oil is hot enough if you put a small piece of bread in it and it immediately starts to bubble.
Pour the cornflour into a shallow dish and season generously with salt and pepper. Pass the chicken through the cornflour and gently dip them into the oil. Fry the chicken in small batches until golden brown and drain on kitchen paper.
To make the sauce, grate the remaining garlic and ginger into a saucepan with the soy sauce, gochujang, brown sugar, honey, sesame oil and half the squeezed lime.
Heat the sauce, stirring constantly, and simmer for 10 minutes. Slice the spring onion into thin rings. Toast the sesame seeds in a frying pan until golden brown.
When all the chicken pieces are fried, toss them through the sauce. Add the sesame seeds and sprinkle with the spring onion. A little chopped coriander is nice on top, but not a must. Delicious with a cold beer :)
