What cocktail uses vodka, cranberry juice, and a lime wedge?

The cocktail that uses vodka, cranberry juice, and a lime wedge is known as a Cosmopolitan. This drink is characterized by its vibrant pink color and a refreshing taste that balances the tartness of cranberry with the crispness of vodka and the zesty lime.

In a Cosmopolitan, vodka serves as the base, providing a smooth and clean flavor. The cranberry juice adds sweetness and tartness, which is essential for the drink's overall profile. The lime wedge not only garnishes the drink but also contributes acidity and brightness, enhancing the other flavors. This combination of ingredients creates a well-rounded, popular cocktail often associated with sophistication and style, particularly in the context of urban nightlife and social gatherings.

The other drinks listed do not include these specific ingredients: a Martini typically features gin or vodka with vermouth, a Bloody Mary is made with vodka and tomato juice along with various spices, and a Margarita is primarily composed of tequila, lime juice, and often orange liqueur. Thus, the specific ingredient combination of vodka, cranberry juice, and lime distinctly identifies the Cosmopolitan.
