"Tex-Mex" (portmanteau of Texan and Mexican) is a term describing a regional American cuisine that blends food products available in the United States and the culinary creations of Mexican-Americans influenced by Mexican cuisine. The cuisine has spread from border states such as Texas and those in the Southwestern United States to the rest of the country as well as Canada. Tex-Mex is most popular in the state of Texas. Tex-Mex is very different from the Southwest cuisine found in Arizona, New Mexico, Colorado, and Utah. 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, other 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 of Texas the term is synonymous with Southwestern cuisine.
