We can all agree on a few things here: Great carne asada should taste, first, of the beef. It should be buttery, rich, and juicy, with a nice charred, smoky flavor from the grill or broiler. It should also be tender enough that you can eat it in a taco or burrito, but substantial enough to be served as a steak and eaten with a knife and fork. Finally, the marinade should have a good balance of flavors, with no single ingredient overwhelming any other. This recipe produces the carne asada of my childhood dreams.
