The tequila sunrise is a cocktail made of tequila, orange juice, and grenadine syrup. It’s served unmixed in a tall glass. The cocktail is named for its appearance when served—with gradations of color resembling a sunrise. The original tequila sunrise contained tequila, creme de cassis, lime juice, and soda water, and was served at the Arizona Biltmore Hotel where it was created by Gene Sulit in the 1930s or 1940s.
