Make a bright, sweet-tart syrup from fresh strawberries and rhubarb to use as a base for homemade soda or sparkling beverages.

Ingredients

Scale
  • 2 cups fresh rhubarb, chopped
  • 2 cups fresh strawberries, hulled and halved
  • 2 cups granulated sugar
  • 1 cup water
  • 1 tablespoon fresh lemon juice

Instructions

  1. Combine the chopped rhubarb, strawberries, sugar, and water in a medium saucepan.
  2. Place the saucepan over medium heat. Stir occasionally until the sugar dissolves completely.
  3. Bring the mixture to a gentle simmer. Reduce the heat to low and cook for 15 to 20 minutes, stirring occasionally, until the rhubarb is very soft and the fruit has broken down.
  4. Remove the saucepan from the heat and stir in the lemon juice.
  5. Allow the mixture to cool slightly, about 10 minutes.
  6. Pour the fruit mixture through a fine-mesh sieve set over a bowl. Press gently on the solids with the back of a spoon to extract as much liquid as possible. Do not force the pulp through the sieve.
  7. Discard the solids. You now have your **best strawberry rhubarb flavor concentrate**.
  8. Pour the strained syrup into clean, airtight jars or bottles.
  9. Cool completely before sealing and refrigerating.

Notes

  • For a clearer syrup, line your sieve with cheesecloth before straining.
  • Store this **rhubarb syrup for sparkling water** in the refrigerator for up to three weeks.
  • To freeze, pour the syrup into freezer-safe containers, leaving an inch of headspace. It keeps well for up to six months.
  • Use a 1:4 ratio (1 part syrup to 4 parts chilled sparkling water) for a standard soda. Adjust to your taste.
  • This **craft soda base recipe** also works well in iced tea or as a drizzle over yogurt.
