Ah, the eternal question. There are several ways to keep your drinks ice cold without adding ice. Try tossing in frozen fruit in place of ice cubes, using reusable ice cubes, or freezing part of the drink in ice cube trays. As it melts, it won't dilute your beverage. To keep everything cold, be sure to chill your ingredients before conjuring up a drink. You can also chill your glassware before adding drinks to it or serve your cocktails in insulated glasses or tumblers. If you've got drinks in larger containers or pitchers, nestle them inside an ice bucket.
