We used to sell halves and quarters of beef to customers who told the butcher how they wanted the meat packaged, and also, if they wanted any extras.
Some Hispanic customers were thrilled to be able to buy whole cow heads for some kind of special BBQ.
This was years ago before the mad cow stuff.
Our family recently bought a half or quarter cow and requested extras (livers). The livers make great pate (yum yum!) Wouldn’t dream of eating the brains though. Just nasty.
You've never had Barbacoa? It's incredible. Here in Texas they sell it
by the pound at a fast Mex called Two Pesos.
