Last night I made fajitas for dinner. I marinated flank steak for about 8 hours in a nicely seasoned marinade that included freshly squeezed lime juice, olive oil, crushed garlic, ground cumin, oregano, chopped cilantro and chili powder. I cooked it on a stove-top grill pan until it was slightly pink. I let the meat rest for about 10 minutes while I cooked sliced onions and bell peppers in the same pan. I sliced the meat at an angle, against the grain, and served it.
In a word -- BLEEECH!!! The meat was totally inedible. It couldn't be chewed. It was my understanding that the lime juice would serve to tenderize the meat. It didn't. Maybe I should mention, FWIW, that the flank steak was pre-packaged and was a Swift Premium product. It was the only flank steak the supermarket carried. I tossed the whole thing in the trash.
I'm thinking that if I ever attempt fajitas again, I'll have to use a better, more tender cut of meat. Or is there something else I need to know about using flank steak?
