Which ingredient is added last in a Tequila Sunrise?

In a Tequila Sunrise cocktail, grenadine is added last to create the signature gradient effect that resembles a sunrise. The drink begins by pouring tequila and orange juice into a glass filled with ice. After these ingredients are combined, the grenadine is slowly poured in so that it sinks to the bottom of the glass. This technique not only adds sweetness but also creates a visually striking color transition from the vibrant orange of the orange juice to the deep red of the grenadine at the base.

This layering is critical to the cocktail's presentation and experience, showcasing the drink's name. While tequila and orange juice are fundamental in constructing the body of the drink, it is the last addition of grenadine that completes the Tequila Sunrise and highlights its aesthetic appeal.
