No disrespect, but I don’t prefer a flat iron steak. Doesn’t mixing dry rub with a liquid sort of defeat the purpose of each? Medium? You assuming he’s cooking for someone squeamish? Small child? That you need to slice it thin is not a great selling point, IMO.
Leaner cuts of meat can be cooked rare or medium rare, depending on the person. I am fine with either. I cook fattier cuts like strip and ribeyes to medium so to allow the fat to render a bit. Most steak joints will make this recommendation as well. No piece of red meat should EVER be cooked over medium, with the exception of ground beef due to their exposure to the air.
i've been marinating skirt steak in olive oil, soy sauce, lemon juice, and beer and searing it quickly on the grill. delicious and great for tacos.
Yeah, if it’s a reputable joint I’ll let them cook it medium, but normal I err on the side of caution.
Make sure it wasnt flank. Flat iron is well marbled and zero waste. My kids love it and does well anytime im feeding a group at the house. They take the slices like chicken fingers and eat it, and ive found rare flat iron tends to be too chewy, vs a filet, which is of course better. I use the same marinade recipe for bison burgers. I like worc sauce and can also taste the Creole, jerk or lawrys that I use.
I like to marinate my steak in Italian dressing and you can’t really undercook it. I’ve never put one back on the grill
Just went to Capital Grille last weekend for their wagyu & wine event (a great deal, btw) and ordered medium rare. I typically never go below medium for burgers, but it was excellent. The risk paid off.
