How to Make Sparkling Raspberry Soda

- Mocktail – Garnish with fresh mint and lime slices for an elegant alcohol-free drink.

Storage
The raspberry puree can be made up to 3 days ahead and stored in an airtight container in the refrigerator. Add the sparkling water just before serving to keep the bubbles fresh.
Common Questions
Can I use fresh raspberries?
Absolutely. Fresh raspberries work just as well when they’re in season.
Can I make this sweeter?
Yes. Add additional sweetener or simple syrup to taste.
Can I use flavored sparkling water?
Definitely. Lemon, lime, berry, or plain sparkling water all pair well with raspberries.
Can I make a large batch?
Yes. Blend a larger batch of the raspberry puree ahead of time, then pour over sparkling water as needed so every glass stays fizzy.
Can I reduce the carbs even more?
Yes. If you’re counting carbs, use about half the raspberry puree for every 12 ounces of sparkling water. The raspberry flavor will be lighter, but each serving drops to about 2 net carbs.
