sparkling raspberry limeade

1¼ cups sugar

6 ounces raspberries, plus more for garnish (about ¾ cup)

1 cup water

1 cup lime juice (juice of 16-25 limes— I used bottled juice)

1½ liters seltzer water

1 lime, thinly sliced, for serving

Combine the sugar, raspberries, and water in a small saucepan. Bring the mixture to a simmer. Stir until the sugar dissolves. Press the berries with back of a wooden spoon so their juices leach into the mixture. Let sit and steep until cool. Strain, discarding the solids.

Combine the cooled raspberry syrup, lime juic and seltzer in a large pitcher. Pour into tall glasses filled with ice and garnish with the lime slices and a few extra berries.
