Lightly fizzy and sweet (but not cloying) with the subtle pepperiness of basil, Strawberry Basil Soda is a perfect pick-me-up on a hot summer afternoon.
Recipe makes about 2 cups syrup.
In a medium saucepan, combine 1 cup water, granulated sugar, strawberry puree, and basil. Bring to a boil over medium-high heat. Lower heat and simmer, stirring occasionally, 5-8 minutes. Remove from heat and cool to room temperature.
Strain cooled mixture through a fine-mesh sieve, pressing to extract juices. Discard solids. Chill syrup until ready to use.
Pour 2-3 tablespoons of strawberry basil syrup into a glass. Fill with ice and sparkling water. Gently stir and add additional syrup to taste. Garnish with a sprig of fresh basil or a strawberry slice.
The strawberry-basil syrup will stay fresh for about 10 days in the refrigerator in a tightly-sealed container. Stir before using.
