In this part of Texas, the carne asada is usually prepared with a rub
only, and the marinates are used more for fajitas. Like everywhere
else, everyone has their traditional recipes for these dishes.
But this rub is about right for a (locally recognized here in San
Antonio) carne asada rub. Let this rub sit on the meat overnight.
