Which ingredient is used to float on top of the Mai Tai?

The ingredient that is used to float on top of a Mai Tai is Myers Rum. A classic Mai Tai is a cocktail that typically includes light rum, lime juice, orgeat syrup, orange liqueur, and sometimes simple syrup. The float of dark rum, often Myers Rum, on top is not only a traditional presentation but also adds depth of flavor and a rich sweetness that complements the other ingredients. When floated, the darker rum creates a visually appealing layer that enhances the overall experience of the cocktail.

In contrast, Amaretto is a sweet almond-flavored liqueur that is not traditionally used in the preparation of a Mai Tai. Triple Sec is an orange liqueur that is part of the cocktail but is mixed with the other ingredients rather than floated on top. Creme de Cassis is a sweet blackcurrant liqueur that is typically utilized in other cocktails, but it does not belong in a classic Mai Tai recipe. The choice of Myers Rum aligns perfectly with the established recipe and expected flavor profile of this iconic drink.
