you won't regret it. The pic on the grill, if there was a piece you felt like tearing off for a sample, it'd pull off with ease. Seemed almost fillet'd (sp??? lol). Good stuff, going to do it again.
For the marinade I squoze an orange with my hands while it was in the peel until it was juicy inside, then I put that, half of a bunch of chopped cilantro, a couple TBSP of minced garlic (from a jar), EVOO, & maybe some pepper in a bag & massaged it a time or two per day for >5 days in the meat drawer. I meant to cook it earlier but that's the way things go around here..
I cooked it direct for ~10 minutes but the meat dripped on the coals & dropped the temp from ~425 to ~275 so I flipped it every 3 minutes, direct with the lid off (sometimes stacked {meat piled}, sometimes spread out) for another 20 minutes or so until it took on a nice color.
