The flat iron is a shoulder cut nobody writes poems about, and I’ll take a good one over a filet most nights. Dry-brine it, sear it hot and fast (550–600°, 2–3 minutes a side), rest it, then pile it on a crunchy blue cheese salad. Full method plus the leftover steak sandwich on the blog (link in bio). The amount of blue cheese is between you and your conscience. More is better.
