  • 1 stalk of rhubarb (approximately ½ cup, chopped)
  • ½ cup of sugar

Combine the chopped rhubarb and sugar in a container with a tight-fitting lid.
Seal the container and shake vigorously to combine.
Let sit overnight at room temperature (or up to 3 days if desired). The longer this sits, the better it will taste!
When the syrup is to your liking, strain through cheesecloth or fine-mesh sieve over a large bowl, reserving the liquid that drains out of the rhubarb.
Save the rhubarb and store the syrup in an airtight container until ready to use!
  • Use fresh rhubarb: If you're lucky enough to have access to local rhubarb in season (April through June), then go for it! Otherwise, look for organic rhubarb from your farmer's market or grocery store. Pick stems with bright green leaves and firm stalks that feel heavy for their size. Stems should be about 3 inches long or longer — any shorter than that, and they'll be too sour for this recipe.Taste, taste, taste: Make sure it's sweet enough before straining it through cheesecloth. Once strained through cheesecloth, the liquid should taste sweet enough to drink on its own (without any additional sugar). If not, add more sugar until it's just right!
