To be a real meat geek - if you really want to know about meat, and I think some of you might, there's some interesting reading out there.
Not too hard to find is "A Field Guide To Meat" - it's a great book for explaining which cuts are called this and that and the other - for each cut, it lists all kinds of names used for that cut. Also talks about how it should be prepared, how much to serve per person and that kind of thing.
Another easy to find on the internet, but expensive as hell - is NAMP's "Meat Buyer's Guide". It's a very official book that slaughterhouses must follow criteria how what muscle can be sold as what, how it should be cut and trimmed. The very nice thing is that the Field Guide to Meat refers to this book - and the Meat Buyer's Guide has very nice pictures.
If you ask your meat department - they should be able to go look at the box any piece of meat came out of - and it should be quite officially labeled by the NAMP standards. Only problem here is it's best to shop in the morning when the guys who actually took it out of the box and packaged it up are still there.
You can educate yourself and get to know what different cuts are by how they look.
I requested the Meat Buyer's Guide from a library - they got me a copy from some rural place.
I'm glad I gave myself this education, because now I can go to the Mexican store and if the names are only in Spanish, which I don't speak, it doesn't matter, I know what meat looks like....
