Raspberry Limeade

Makes about 5 cups, serving 4

2 cups raspberries, divided
3 1/2 cups water, divided
3/4 cup granulated sugar, or to taste, divided
1 cup fresh lime juice
Mint sprigs for garnish

In a blender or food processor puree 1 cup of the raspberries with 1 cup of the water and force the puree 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; 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.
