Step 1

Place the water, sugar, and blueberries in a medium saucepan set over medium to medium-high heat. Bring the mixture to a boil and cook for 5 minutes, or until the sugar has dissolved and the blueberries have burst. Mash the blueberries a bit, to release more flavor and color.

Step 2

Remove saucepan from heat and stir in the basil. Cover with a lid and steep for 20 minutes.

Step 3

Strain the syrup through a fine mesh sieve, pressing on the solids a bit to release more flavor and color. Discard solids.

Step 4

Add blueberry syrup, lemon juice, and sparkling water to a pitcher. Stir to combine.

Step 5

Enjoy this lemonade over ice, garnished with lemon, blueberries, and/or basil leaves.
