12 servings (serving size: 2/3 cup spritzer and 1 lime slice)
2 1/2 cups water
3/4 cup sugar
2 pounds rhubarb, cut into 1-inch pieces
2 tablespoons fresh lime juice
1 (25-ounce) bottle sparkling water, chilled
12 lime slices
How to Make It
Combine first 3 ingredients in a large saucepan; bring to a boil. Cover, reduce heat, and simmer 10 minutes. Strain mixture through a sieve into a bowl, pressing rhubarb with the back of a spoon to remove as much liquid as possible. Discard solids. Cool to room temperature. Stir in juice. Cover and chill.
Stir in sparkling water just before serving. Garnish with lime slices.
