The Gochu Yurinyuk from Paik's Noodle

I think that sauce is supposed to be poured over those fried slices of pork in the background, but we just used it as a dip. And that dip was more fragrant and spicy than I thought it would be, all without being syrupy. Anyway, this was from Paik's Noodle, whose jjajangmyeon is still unbeaten in my limited exposure to the dish. The other ones that I've tried, including from Noodle Star K recently, just didn't have that earthy onion-focused aroma.
