Sambuca is a potent Italian liqueur that is typically colorless and has a strong anise (licorice) flavor. The primary ingredients in Sambuca include star anise, green anise, elderflower, and a neutral base spirit. It is often enjoyed on its own as a digestif, but it also serves as a versatile ingredient in cocktails, adding a distinctive licorice note that can complement or contrast with other flavors.

In the context of cocktails, Sambuca can be used to create unique and aromatic drinks. For example, it pairs well with coffee in the classic "Caffè Correto," where a shot of Sambuca is added to espresso. It can also be a surprising twist in a variety of mixed drinks, bringing complexity and a hint of sweetness. Sambuca’s strong flavor means that a little goes a long way, making it a powerful component in any cocktail it graces.
