While at the Rego Park Costco, I looked for some skirt steak, which I couldn't find. I asked someone working in their meat department if they ever sold this particular steak, to which he said "no, never, but we have plenty of flap meat which is like the same." I took a look at the flap meat, and while it did resemble skirt steak, I just wasn't sure if it would really taste like skirt steak or not. Would anyone here be able to tell me just how similar flap meat is to skirt steak? Many thanks in advance!
