Ingredients

  • 3 1/2 cups water
  • 5 cups chopped rhubarb, fresh or frozen (20 ounces)
  • 3/4 cup sugar
  • 2 3-inch strips lemon zest
  • 3 sprigs fresh mint
  • 1 cup freshly squeezed lemon juice
  • 2 cups lemon-lime soda or sparkling water

Method

  • In a saucepan, stir together the water, the rhubarb pieces, the sugar, the lemon zest and the mint. Bring the mixture to a boil, stirring until the sugar is dissolved. Reduce heat, cover and simmer for 20 minutes.
  • Let the rhubarb mixture cool, the strain it through a wire-mesh strainer set over a large pitcher. Press on the solids to extract as much liquid as possible. Discard the solids.
  • Stir in the lemon juice and soda. Serve over ice, garnished with a sprig of mint.
