The tequila chaser made from tomato juice, citrus, and hot sauce is called sangrita.
Sangrita is a nonalcoholic Mexican accompaniment traditionally served alongside a shot of tequila. Its name means “little blood,” a reference to its red color. Recipes commonly include tomato juice, orange or lime juice, chili, and savory seasonings, although regional and household versions differ.
The traditional pairing is often presented as separate pours: tequila in one glass and sangrita in another. The drinker alternates between them rather than mixing the ingredients into the tequila. This serving style is sometimes called a bandera, or “flag,” when tequila, lime juice, and sangrita create the colors associated with the Mexican flag.
Sangrita is not the same as a Bloody Mary. A Bloody Mary is an alcoholic cocktail that usually contains vodka, while sangrita is a nonalcoholic chaser designed to accompany tequila.
