Rhubarb lemonade is a delicious, refreshing twist on a classic summer drink. The tartness of rhubarb and fresh lemon juice are balanced with just the right amount of sweetness.
Stir the rhubarb, sugar and water together in a medium saucepan.
Bring to a boil over medium heat, then simmer for 15 minutes. Allow to cool.
Strain the rhubarb mixture using a fine mesh strainer over a bowl. Discard the puree or reserve it for another use. You should have about one cup of simple syrup.
Make the rhubarb lemonade
Combine the lemon juice, rhubarb simple syrup, and cold water in a large pitcher.
Serve over ice, with optional garnishes.
Notes
Rhubarb leaves. Only use the stalks of the rhubarb plant. Never eat the rhubarb leaves; they contain a toxin called oxalic acid, which is poisonous to humans and animals.
Rhubarb puree. After straining the syrup from the cooked rhubarb, you'll end up with a lovely rhubarb puree. Don't let it go to waste. You can use it for topping ice cream or yogurt. You can even spread some on your toast.
Strawberry rhubarb lemonade. Add some chopped strawberries to the rhubarb and sugar mixture before cooking for a classic strawberry rhubarb flavor.
Extra lemon. Add a strip of lemon peel to the mixture to intensify the lemon flavor.
Garnish. Dress up your drinks with lemon slices, strawberries, or sprigs of mint.
Spike it. Stir in vodka or gin for a delicious cocktail.
Add bubbles. Replace the water with sparkling water or club soda for a refreshing rhubarb mocktail.
Ice. Use ice in the glass, not in the pitcher, where it will dilute the drink as it melts.
Storage. Rhubarb lemonade will keep, covered in the fridge for up to five days.
Freezing. My favorite way to freeze is to freeze the simple syrup in ice cube trays, then pack the cubes into an airtight container. Freeze for up to a month.
