Which ingredient is NOT found in a typical Tequila Sunrise?

In a typical Tequila Sunrise, the primary ingredients include tequila, grenadine, and orange juice. This cocktail is characterized by its gradation of color, resembling a sunrise, created by the layers of orange juice and grenadine. While lime juice is a common ingredient in many cocktails, it is not included in the classic formulation of a Tequila Sunrise. The drink relies on the sweetness of grenadine and the citrus flavor from orange juice, which together pair harmoniously with the tequila. Thus, lime juice is the ingredient that does not belong in a traditional Tequila Sunrise recipe.
