Key Ingredients & Their Roles
- Rhubarb: Provides the tart, fruity base; fresh and frozen both work well.

- Water: Helps dissolve the sugar and extract flavors; adjust for syrup thickness.
- Lemon Juice: Adds brightness; consider swapping with lime for a twist.
How to Make Rhubarb Syrup
- In a medium saucepan, combine 4 cups of chopped rhubarb, 1 cup of granulated sugar, and 1 cup of water. The vibrant pink rhubarb adds a beautiful hue as it begins to heat.
- Bring the mixture to a gentle boil over medium heat, then reduce to a simmer. Cook for 15-20 minutes, stirring occasionally, until the rhubarb fully breaks down and the syrup thickens slightly. The aroma that fills the kitchen during this time is invigorating!
- Stir in 1 teaspoon of lemon juice for added zing, if desired.
- Remove the pan from heat and let it cool for about 20 minutes. Once cooled, strain the syrup through a fine mesh sieve into a clean jar, pressing down gently to extract the liquid.


Pro Tips & Troubleshooting
- During my tests, I discovered that the fresh rhubarb produced a bolder flavor compared to frozen. Be sure to chop it into even pieces for consistent cooking.
- A common mistake is rushing the simmering process. If you don’t allow enough time for the rhubarb to break down, the syrup may be too chunky. Just let it simmer patiently!
- For a fun variation, try infusing the syrup with fresh herbs like mint or basil during cooking.
- This recipe scales easily; you can double or halve the quantities without affecting the taste.
