Ingredients

　　2 cups raspberries

　　3 1/2 cups water

　　3/4 cup sugar, or to taste

　　1 cup fresh lime juice

　　Mint sprigs for garnish

　　In a blender or food processor purée 1 cup of the raspberries with 1 cup of the water and force the purée through a fine sieve set over a pitcher, pressing hard on the solids. Add the remaining 1 cup raspberries, the remaining 2 1/2 cups water, the sugar, and the lime juice and stir the mixture until the sugar is dissolved. Divide the limeade among tall glasses filled with ice cubes and garnish each drink with some of the mint sprigs.
