Which ingredient is NOT used in Keoke Coffee?

Keoke Coffee is a specialty coffee cocktail that combines coffee with various liqueurs, traditionally Kahlua (a coffee liqueur) and brandy or a similar spirit. The drink is typically prepared hot and served in a coffee mug or a similar glass. Key ingredients include coffee, Kahlua, and often sugar to sweeten the drink to taste.

A splash of soda water is not a typical ingredient in Keoke Coffee. The purpose of this drink is to maintain its warm, rich coffee flavor enhanced by the liqueurs, and the addition of soda water would alter the drink's character, making it less about the warmth and complexity of the coffee and more about carbonation.

This distinction is essential for understanding how to correctly prepare and serve this cocktail.
