Instructions

1. Preheat oven to 400°F. Toss strawberries, vinegar, and salt on a foil-lined rimmed baking sheet. Bake 20 minutes or until berries have softened.
2. Transfer strawberries to a blender; add ½ cup water. Blend on high speed until smooth. Strain mixture through a sieve; discard solids. Chill strawberry mixture 15 to 20 minutes.
3. Meanwhile, bring ½ cup water, sugar, and basil to a boil in a small saucepan over medium-high heat. Reduce heat to low, and simmer 5 minutes, stirring occasionally. Strain mixture through a sieve, discard solids, and chill basil syrup.
4. Add strawberry mixture to basil simple syrup, and stir. Fill 4 old-fashioned glasses with ice. Spoon 3 Tbsp strawberry syrup into each glass, fill with sparkling water, and stir. If desired, garnish with additional strawberries and fresh basil.
