A beautiful homemade rhubarb soda made with a simple 3 ingredient rhubarb simple syrup and sparkling water. Top with edible flowers for a stunning summer mocktail or cocktail.
Wash and chop your rhubarb stalks into roughly one inch pieces. Discard the leaves as they are not edible.
2 cups fresh rhubarb
Add the chopped rhubarb, sugar, and water to a medium saucepan. Bring to a boil over medium high heat, stirring until the sugar dissolves. Reduce heat and simmer for 10 minutes until the rhubarb is very soft and the syrup is a deep pink color.
1 cup granulated sugar, 1 cup water
Pour the mixture through a fine mesh sieve set over a bowl or large measuring cup. Stir the rhubarb gently in the sieve rather than pressing it down to keep your syrup clear and beautiful. You should have approximately 1 to 1.5 cups of syrup. Don't throw away the rhubarb solids, see our tips for delicious ways to use them up.
To Make Rhubarb Soda
Fill a glass with ice. Add 2 tablespoons of rhubarb syrup and top with 1 cup of sparkling water. Stir gently to combine. Float a few edible flowers on top, add a straw, and serve immediately.
Choose deep red rhubarb stalks for the most vibrant pink color in your syrup.
Sparkling water is the clear winner here. We tested with Sprite (too sweet) and tonic water (too bitter), plain sparkling water lets the rhubarb flavor really shine.
Double the batch for a party of 4 or more.
The syrup keeps in an airtight container in the refrigerator for up to two weeks.
Frozen rhubarb works perfectly, no need to thaw before using.
Add 1.5 oz of vodka or gin to turn this into a summer cocktail.
