Ingredients
4 cups water
1 pint (about 2 cups) raspberries, plus more for garnish
1 3/4 cups sugar
Classic Homemade Lemonade, or 1 quart store-bought lemonade
Ice, for serving
1 bottle (750 milliliters) sparkling water
2 cups vodka (optional)
Preparation
Bring water, raspberries, and sugar to boil in a large saucepan, stirring occasionally, until sugar dissolves. Reduce heat, and let simmer for 15 minutes. Strain mixture through a fine sieve, pressing gently on berries to release juices; discard solids. Let syrup cool completely. Combine syrup and lemonade in a large pitcher. Divide among 16 ice-filled glasses. Top each with sparkling water, and vodka if using. Garnish with fresh raspberries.
