The Cosmopolitan is a popular cocktail that gained fame in the 1990s. It is made with vodka, cranberry juice, lime juice, and triple sec. The combination of these ingredients creates a sweet and tart drink that is both refreshing and sophisticated. To make a Cosmopolitan, mix 1.5 ounces of vodka, 1 ounce of cranberry juice, 0.5 ounces of lime juice, and 0.5 ounces of triple sec in a shaker with ice. Shake well and strain into a chilled martini glass. Garnish with a lime twist and enjoy!
