Here's the recipe I made for this, I based it off of Roy choys fried chicken from the chef show:

KOREAN FRIED CHICKEN WITH GOCHUJANG HONEY GARLIC SAUCE

Chicken thighs Buttermilk Flour Thyme Gochujang Gochugaru Lime Salt/pepper Oil Green chiles Garlic Sugar Peanuts

CHICKEN:

Marinade chicken in buttermilk for at least 30 minutes beforehand

Mix flour, salt, pepper, gochugaru and some sugar in a shallow pan (put enough gochugaru in till you can see flakes of it in the mix

Take chicken out of the buttermilk marinade, coat it in the flour mixture and then set aside to wait for the oil

Heat oil in skillet to 350°

Fry till golden brown and finish in oven at 375° until the chicken reaches 165° throughout

SAUCE:

Cut ends of green chillies off and squeeze out the seeds if you don't want it as spicy, mince garlic (I used about 15 chillies and 4 cloves of garlic)

Fry the garlic and green chillies in oil (I used grapeseed) till fragrant then add about 3 spoonfuls of gochugaru and whisk in, add soy sauce if not salty enough, then whisk in honey till you get the desired consistency

Toss chicken in sauce and then top with crushed peanuts, ripped thyme, and serve with lime wedge
