Texas is defined in many ways by many different people. But there are at least three things anyone can agree on when it comes to the Lone Star State: barbecue, Tex-Mex and steaks. This is the holy trinity of Texas cuisine — foods that compose our most firmly entrenched food heritage. These are the foods we invented or perfected. They are our exports to the world, our richly flavored history, and although we may agree on them in broad strokes, they are also our favorite things to fight over.
