Which ingredient is NOT used in a Sombrero cocktail?

The Sombrero cocktail is a classic drink known for its simple and rich flavor profile. It primarily consists of Kahlua, which is a coffee-flavored liqueur, and cream, which adds a smooth texture to the drink. Additionally, ice is an essential ingredient, as it is typically served chilled, either shaken or stirred with ice.

Vodka is not a component of the Sombrero cocktail. While vodka is a versatile spirit used in many cocktails, it does not belong in this specific recipe, which focuses on the combination of coffee liqueur and cream. Understanding the specific ingredients and their roles in cocktail recipes is crucial for effective bartending, as it ensures the drink maintains its intended flavor profile and character.
