Mate, I literally made this last Friday. Took me about half an hour to double shallow fry all the chicken but damn was it worth it. Ate it with rice, kimchi, and some stir fried cabbage. Nice job!

Oh yeah, tip is to add an egg after the chicken is starched, then mix it a little more. Without it, my batter tended to let loose and not get as crispy. Double fry for extreme crunch, which then gets softened by the sauce.
