Mix about 500g boneless chicken pieces (or chicken wings, ideally) with garlic salt, a little pepper, cornflour and just a little water to help coat the chicken well. Deep-fry till golden, and set aside.
For the sauce, in a very lightly greased saucepan, add a spoon of grated onion, a spoon of garlic paste, half a spoon of grated ginger, a small spoon of soy sauce, a proper spoon of rice wine, a spoon of chilli sauce, a spoon of sugar, a spoon of red chilli paste, a spoon of honey, and a pinch of Dijon mustard.
Now here's the funny part - I didn't feel like leaving home to go get fresh groceries, so here's what I really put in the experimental sauce: a spoon of grated onion, a spoon of garlic paste, half a spoon of grated ginger, a few drops of soy sauce, a proper spoon of sushi seasoning (which is rice vinegar + salt + sugar), a tiny dash of Sriracha, no additional sugar, a spoon of honey, a spoon of red chilli paste, and a few drops of kasundi, which is basically Bengali-style Dijon mustard. I'm amazed at how well it imitated an authentic dakgangjeong sauce!
