Basic Rhubarb Simple Syrup Recipe
| Ingredient | Amount |
|---|---|
| Rhubarb (chopped) | 4 cups (about 6–8 stalks) |
| Water | 1 cup |
| Sugar | 1 cup |
| Orange peel (optional) | 2–3 strips |
Step-by-Step Instructions
- Combine ingredients: Place rhubarb, sugar, and water in a heavy-bottomed saucepan. If desired, add orange peel or other flavorings.
- Cook: Bring the mixture to a boil over medium-high heat, then reduce heat to maintain a gentle simmer. Stir occasionally.
- Simmer: Cook for 20–25 minutes, until rhubarb is very soft and all sugar is dissolved.
- Strain: Pour the mixture through a fine mesh strainer into a bowl, pressing the rhubarb to extract maximum liquid.
- Bottle: Transfer syrup to a clean bottle or jar and refrigerate. Use within two weeks for best flavor.
Tips for Success

- For longer storage, use sterilized jars and process in a water bath for 10 minutes.
- The syrup will thicken as it cools. Shake or stir before using.

Nutrition Insights
Rhubarb stalks are low in calories and provide Vitamin K, fiber, and antioxidants. When transformed into simple syrup, the calorie count increases due to sugar. For reduced sugar options, substitute with honey or agave, understanding this will alter shelf life and flavor.
Expert Tips for the Best Results
- Choose crisp, deep red rhubarb stalks for better color and flavor.
- Stir gently while simmering to help rhubarb break down and avoid sticking.
- If syrup thickens too much during cooling, thin with a little water before bottling.
