Recently I've been experimenting with grilling beef short ribs. I don't mean the flanken cut kind like are common at Korean & Hawaiian restaurants and Teriyaki joints, I mean English cut short ribs with the whole bone in them.
Typically these are considered better for braising, but I've had really good success with grilling them. Grilling them is pretty common in Argentina, I guess.
I've done them twice. Once I had very short ones (where the bones have been cut in half) and once I had longer ones (where the bones were full length).
The shorter ones I put in the smoker at low temp (~200 degrees) for about an hour, then I finished them on a charcoal grill. The longer ones I pre-cooked in a sous vide bath at 126 degrees for 3 hours, then put in a low temp smoker for 45 minutes, then finished on the grill.
In both cases they were well seasoned with sea salt and fresh ground pepper.
They came out great both times. I sliced the meat off the bone and then cut the resulting slab of meat into slices roughly 1/4" thick. The meat was rare to medium rare, with a nice sear on the outside. I wouldn't call the results exactly tender, but the meat wasn't tough either. It had a pleasant amount of chew and an intensely beefy flavor, a pleasant smokiness and a crisp fat cap along one edge.
Admittedly, it is a bit of a process, but I really like turning a cheap cut of meat into something awesome.
I didn't have any chimichurri sauce either time, but it would be a great with them. Instead I had some gochujang on the side to dip them in.
