Clean and remove the stems from the fresh strawberries and add to a blender.
Wash, remove, and discard the leaf from the rhubarb stems, cut into smaller pieces, add to the blender.
Add water, pulse to combine, and let this sit for about 10 to 15 minutes.
Place a fine mesh strainer over a quart jar and pour the mixture into the strainer, separating the solids from the liquid.
Save the solids for later use or discard.
Pour the mixture into a small pitcher or quart jar and store in the refrigerator when ready to serve.
When ready to serve, add ice, pour about a half of a glass of the mixture and then add sparkling water.
Garnish with fresh strawberries or sliced rhubarb and enjoy!
