Ingredients
- 4 cups fresh rhubarb, chopped into small pieces
- 2 cups granulated sugar
- 2 tablespoons fresh lemon juice
- 1 teaspoon vanilla extract, optional
- 2 tablespoons water
Instructions
1. Prepare the Rhubarb
Wash the rhubarb stalks thoroughly and trim off the leaves and the dry ends. Do not use rhubarb leaves, as they are not suitable for eating.
Cut the rhubarb stalks into small pieces, about ½ inch in size. Smaller pieces cook down faster and create a smoother jam.
2. Combine the Ingredients
Place the chopped rhubarb, sugar, lemon juice, and water in a large, heavy-bottomed saucepan.
Stir everything together and let the mixture sit for about 10–15 minutes. This gives the sugar time to draw moisture from the rhubarb.
3. Start Cooking
Place the saucepan over medium heat and bring the mixture to a gentle boil.
As the rhubarb heats, it will release more liquid and begin to soften. Stir regularly, especially around the bottom of the pan, to prevent sticking.
4. Cook the Jam
Reduce the heat to medium-low and continue cooking for approximately 25–35 minutes.
Stir frequently as the mixture thickens. The rhubarb will break down and the mixture will gradually become glossy and jam-like.
If you see foam forming on the surface, you can gently skim it off with a spoon.
5. Check the Consistency
To test whether the jam is ready, place a small spoonful on a cold plate and let it sit for about 30 seconds. Push the jam gently with your finger or spoon.
If it wrinkles slightly and doesn’t immediately run back together, the jam is ready.
Remember that the jam will become thicker as it cools, so don’t cook it until it becomes extremely thick in the saucepan.
6. Add Vanilla
If using vanilla extract, stir it into the finished jam after removing the saucepan from the heat.
Taste carefully. If you prefer a sweeter jam, you can adjust the flavor next time by slightly increasing the sugar.
7. Cool and Store
Allow the jam to cool for several minutes before transferring it to clean jars.
For refrigerator storage, place the cooled jam in clean airtight containers and refrigerate.

Tips for the Best Rhubarb Jam
Choose Fresh Rhubarb
Look for firm, fresh stalks without soft or damaged areas. The color can range from green to pink or red depending on the variety. Color doesn’t determine whether the rhubarb is good.
Cut the Rhubarb Evenly
Cutting the stalks into similar-sized pieces helps everything cook at roughly the same rate.
Don’t Rush the Cooking
Cooking the jam gently allows the rhubarb to soften properly while the liquid evaporates. Keep stirring as it thickens.
Don’t Overcook
Rhubarb jam can become much thicker after cooling. If it looks slightly loose while hot, that’s often perfectly fine.
Storage
For a simple refrigerator jam, keep the finished jam in a clean, airtight container in the refrigerator and use it within a reasonable refrigerated storage period.
For shelf-stable canning, use a tested canning recipe and proper water-bath canning procedures rather than relying on this refrigerator-jam method.
Easy Rhubarb Jam Variations
Strawberry Rhubarb Jam
Replace 1–2 cups of the rhubarb with chopped strawberries. The strawberries add sweetness and a lovely fruity flavor.
Ginger Rhubarb Jam
Add a small amount of freshly grated ginger while cooking for a warm, slightly spicy flavor.
Orange Rhubarb Jam
Add a little finely grated orange zest along with the lemon juice. Orange and rhubarb make a delicious combination.
Cinnamon Rhubarb Jam
Add a small cinnamon stick while cooking, then remove it before transferring the jam to the jar.
