What is the primary ingredient in a Sombrero?

The primary ingredient in a Sombrero cocktail is Kahlua, which is a coffee-flavored liqueur. This drink is made primarily to highlight the rich, sweet flavor of Kahlua, which is essential for creating the unique taste profile of the Sombrero. Typically, the drink is prepared by combining Kahlua with cream or milk, making it a creamy and indulgent cocktail that appeals to those who enjoy coffee flavors.

Kahlua's prominence in the drink allows it to serve as a base that anchors other flavors, presenting a robust yet smooth flavor experience. The other ingredients listed, such as whiskey, rum, or Amaretto, would not provide the same coffee-centric profile that Kahlua does, which is why Kahlua is recognized as the primary ingredient in this cocktail.
