If you have fresh rhubarb to use up, this Rhubarb Lemonade is a delicious way to enjoy it. Homemade rhubarb syrup and fresh lemon juice come together for a drink that's perfectly sweet, tart, and refreshing.
Make the rhubarb syrup ahead of time, then mix up a pitcher whenever you're ready to serve. It's perfect for warm summer days, barbecues, or relaxing on the porch.

If you are looking for other summer drinks, let me suggest a few I love! First, let's not forget the classic lemonade. Or how about a virgin pina colada? Mint grapefruit mocktails have quickly become a favorite flavor combo of mine.
Ingredients
You'll only need a few simple ingredients:
- Rhubarb – Fresh or frozen both work well.
- Granulated sugar – Used to make the rhubarb syrup.
- Fresh lemon juice – Freshly squeezed gives the best flavor.
- Water – Still or sparkling, depending on your preference.
How To Make
- Combine the rhubarb, sugar, and water in a saucepan and cook until the rhubarb is very soft.
- Strain the mixture, pressing gently to extract as much syrup as possible. Let the syrup cool.
- Stir the rhubarb syrup together with the fresh lemon juice, then add cold water to taste.
- Serve over ice with lemon slices or a few pieces of fresh rhubarb, if desired.





Recipe Tips
