The phrase "Tex Mex" was reportedly coined in the early 20th century by journalists in Texas during the 1920's. What we consider to be a term to describe southwestern cuisine was initially used to describe Texas residents who were of Mexican descent. "Tex-Mex" quickly became associated with food, yet it is more accurately used to describe Mexican style food that is served in South Central and Southeast Texas. Mexican food or Tex-Mex, is quite popular in The Woodlands boasting than 30 active Mexican Food Restaurants serving fajitas, margaritas and more, scheduled to open in the future.
"Tex-Mex" (portmanteau of Texas and Mexican) is a term used to describe a regional American cuisine that blends food products available in the United States and the culinary creations of Mexican-Americans influenced by the cuisines of Mexico.
Tex-Mex is most popular in the southern state of Texas and the southwestern state of Arizona. Tex-Mex is very different from the southwest cuisine found in New Mexico, Colorado, and Utah. In these areas, the preferred southwest cuisine is New Mexican cuisine.
The southwestern state of Nevada and West Coast state of California tend to lie in the middle as far the preferred style of Mexican-American food. In some places, particularly outside of Texas, "Tex-Mex" is used to describe a localized version of Mexican cuisine. It is common for all of these foods to be referred to as "Mexican food" in Texas, parts of the United States, and some other countries.
In other ways it is Southern cooking using the commodities from Mexican culture. In many parts of the U.S. outside Texas, and Arizona, the term is synonymous with Southwestern cuisine.
