done a flat iron steak. salt/pepper, rested 2 hrs, 250'F oven for 2.5 hrs on a rack over a grill pan.
scrumptious only starts the descriptors.... I like mine med rare; DW only does "no red" - so I chunked off a pc, boosted the oven to 375'F - ten minutes including time to temp and she's happy. she happy = me happy.....
had flat iron on my shopping list for quite some time - waiting for a sale. it's like shanks - used to be economical, then got trendy - not cheep anymore!
typically 2-3 days after I buy one it goes on sale.... we'll see. I've found flat iron doesn't suffer from freezing, so I'm prone to buying up a batch on sale.
