Which cocktail is recognized for including egg whites?

The Whiskey Sour is recognized for including egg whites because this ingredient is used to create a creamy texture and add body to the cocktail. The combination of egg whites with the other typical ingredients—whiskey, lemon juice, and simple syrup—results in a smooth and frothy consistency when shaken. This not only enhances the mouthfeel but also contributes to the cocktail's visual appeal by creating a foamy top layer.

In contrast, the other cocktails listed do not traditionally include egg whites. The Mai Tai is a rum-based drink that focuses on citrus and almond flavors; the Pina Colada is a creamy, tropical beverage made with rum, coconut cream, and pineapple juice; while the Daiquiri consists of rum, lime juice, and sugar, typically served without any eggs. Therefore, the Whiskey Sour stands out as the cocktail known for incorporating egg whites, aligning with the classic preparation methods recognized in cocktail culture.
