What citrus fruit is commonly used as a garnish in cocktails?

The use of citrus fruits as garnishes in cocktails enhances both the flavor and visual appeal of the drink. Each of the fruits listed—orange, lemon, and lime—has distinct characteristics and is widely recognized for its role in mixology.

Oranges are often used for their sweet and refreshing flavor, and their vibrant color makes for an attractive garnish, especially in cocktails like the Old Fashioned or tropical drinks. Lemons are valued for their tartness and are commonly garnished in drinks like whiskey sours or gin and tonics to provide a bright contrast to the alcohol. Limes are a staple in many cocktails, particularly in classics like the Mojito and Margarita, where their sharp acidity balances the sweetness and provides a zesty punch.

Given that all three of these citrus fruits are popular choices for garnishing a wide range of cocktails, the correct answer encompasses the idea that any of these fruits can serve as an effective garnish. Their versatility and complementary flavors contribute to their status as essential garnishes in the cocktail world.
