President Kennedy often toasted with this cocktail throughout our country’s age of Camelot. Still, the daiquiri remains the "alcoholic slurpee" that we know and love today. The traditional recipe calls for 2 ounces rum, 1 ounce limejuice, and 1/2 teaspoon of sugar syrup, shaken with ice, served in a cocktail class glass. But the blended version is more common now. Should you decide to whip up a batch, add your fresh fruit of choice (think strawberry, banana, or mango) to sweeten the offerings. Or create a virgin version—a surefire hit with any underage guests at the party.
