Place the beef in a mixing bowl.
In a small food processor or blender, drop in the garlic and ginger.
Add the doenjang, gochujang and sugar.
Pour in the soy sauce, rice wine, rice vinegar and sesame seed oil.
Add a quarter cup of water and process to make the marinade.
Taste and adjust the flavor, if you prefer.
Add the marinade to the beef, mix well and leave for fifteen minutes (the meat will soak up all the marinade).
Thread the beef with skewers.
Heat the grill and cook the beef skewers over high heat, in batches if necessary to avoid overcrowding, about two minutes per side.
Serve your Korean grilled beef skewers as an appetizer or with rice as a main course.
