With beef from Argentina, you can usually see where the Jockey hit the animal.
I did a short-term gig in Venezuela in the late '80s. The first time I went to a butcher shop, I saw that the meat was a deep burgundy color without a trace of marbling. I asked the guy where it came from and he said "Argentina".
The locals told me the color came from the cattle being range-fed and not penned up and doped like in the States. You could almost cut the meat with your fork. When I got back home, our scarlet-red meat looked fake.
Argentina produces some of the best beef in the world. That's one of the things I look forward to whenever I go there.
