Korean Short ribs are cut from thin cross sections of the first four to five ribs, where there is a nice ratio of meat to bone. Korean short ribs are amazing when marinated and charred on a grill.
For traditional Kalbi (Galbi), use a soy and brown sugar based marinade. This cut will soak in a lot of flavor given enough time, so allow it to marinate for at least 4 hours (ideally overnight). Grill over high heat for 3-5 minutes. For BBQ Short Ribs, simple grill over high heat then douse with your favorite sauce.
