premise: Other food names that have passed through the Texas pipeline into common usage are chile, enchilada, taco, tamale, tortilla, fr?­jol, frito, picante, jalape??o, nacho, mescal, tequila , and margarita .  It may be interesting to note the Spanish borrowed chile, tamale, mescal , and mesquite from the indigenous Indians before passing them on to us.
hypothesis: Food being delicous allows language to pass across borders easier.
