If you’re looking to identify the distinguishing characteristics of Tex-Mex, enchiladas are a good case study. In the classic Tex-Mex version of cheese enchiladas, grated yellow cheese is wrapped in tortillas, and then covered in a dark red chili sauce mixed with ground beef. You’ll also find other typical Tex-Mex ingredients like pinto beans and rice served on the side. But Iliana de la Vega, the chef and owner of the Mexican restaurant El Naranjo in Austin, never ate cheese enchiladas while growing up in Mexico City. She recalls eating foods like chiles rellenos and salads composed of chayote or nopales. Beef was a bit of a rarity. “In traditional Mexican cooking, we eat a lot of chicken and a lot of pork,” she explained. If they had enchiladas, they were usually smothered in a green tomatillo sauce or mole, and sprinkled with a white cheese. “My mother was from Oaxaca, so we had mole maybe twice or three times a month,” she said.
