Kristin Donnelly'S Watermelon Agua Fresca

• 6 cups chopped seedless watermelon (about 2 pounds after chopping, or 4 to 5 pounds before)
• 3 tablespoons fresh lime juice
• 1/4 cup sugar
• 16 to 20 drops Angostura bitters
• 1 1/2 cups club soda, chilled
• 1 cup ice cubes
• 1 lime, thinly sliced, for serving

1. In a blender or food processor, puree the watermelon. Strain the juice through a sieve into a pitcher. Add the lime juice, sugar, and bitters and stir with a long-handled spoon until the sugar is dissolved. Refrigerate for at least 1 hour.
2. Add the club soda, ice cubes, and sliced lime to the agua fresca and serve.
3. Notes: The agua fresca base can be refrigerated for up to 2 days. Add the club soda, ice cubes and sliced lime just before serving. For a large party, the recipe scales up well, and you can serve this in a punch bowl or wide-mouthed canister with a ladle.
