The pretty purple hue of this soda comes from a simple homemade blueberry syrup.

Special equipment: fine mesh sieve, cheesecloth
serves 1 soda, enough blueberry syrup for 6 sodas, active time 15 minutes, total time 25 minutes
- For the Blueberry Syrup:
- 8 ounces (a scant 2 cups) frozen blueberries
- 3/4 cup water
- 3/4 cup sugar
- 3/4 tablespoons juice from 1 lemon
- For Each Soda:
- 1/4 cup blueberry syrup
- 1 tablespoon lime juice from 1 lime
- 8 ounces seltzer
For the Blueberry Syrup: Combine the blueberries and water in a small saucepan over low heat until soft enough to smash easily with the back of a spatula, about 5 minutes. Carefully mash the blueberries with a potato masher until none remain whole. Increase the heat to medium and keep the mixture at a steady simmer for 8 minutes, stirring frequently. While the blueberries cook, place the sugar in a large heatproof bowl. Line a fine mesh sieve with cheesecloth and place it over the bowl. Carefully pour the blueberry mixture into the sieve and allow it to drip until the dripping becomes intermittent, about 5 minutes. Lift up the sieve and stir the syrup until the sugar is dissolved. Place the sieve back on the bowl and allow to drip until the dripping stops, about 5 minutes longer. Save the solids for another use. Let the syrup cool to room temperature and refrigerate.
For the Soda: Combine blueberry syrup, lime juice, and seltzer. Stir to combine, top with ice to fill, and serve immediately.
