Recipe Summary
Prep Time: 15 minutes
Cook Time: 15 minutes
Total Time: 30 minutes
Yield: About 2 small jars
Course: Jam, Spread, Preserves
Cuisine: Homemade
Ingredients
- 2 cups rhubarb, chopped
- 2 cups granulated sugar
- ¼ cup water
- 1 tablespoon lemon juice
- 1 packet fruit pectin
Ingredient Notes
Rhubarb
Use fresh rhubarb stalks that are firm and crisp. The stalks can be pink, red, or green. All will work, though red rhubarb gives the jam a brighter color.
Do not use rhubarb leaves, as they are not edible.
Sugar
Sugar balances the tartness of the rhubarb and helps the jam set properly. Since rhubarb is naturally very tart, the sugar is important for both flavor and texture.
Lemon Juice
Lemon juice brightens the flavor and helps the jam taste fresh. It also supports the setting process.
Fruit Pectin
Fruit pectin helps the jam thicken quickly and gives it a spreadable texture.
How to Make Perfect Rhubarb Jam
Step 1: Prepare the Rhubarb
Wash the rhubarb stalks well.
Trim off the ends, then chop the stalks into small pieces, about 1 inch or smaller.
Smaller pieces cook down more evenly and help create a smoother jam.
Step 2: Combine the Ingredients
Add the chopped rhubarb, sugar, water, and lemon juice to a large pot.
Stir everything together until the rhubarb is coated in sugar.
Step 3: Add the Pectin
Sprinkle the fruit pectin over the rhubarb mixture.
Stir well to dissolve the pectin and prevent clumps.
Step 4: Cook the Jam
Place the pot over medium heat.
Bring the mixture to a gentle boil, stirring often.
Cook for about 10 to 15 minutes, or until the rhubarb softens, breaks down, and the jam thickens.
Step 5: Test the Texture
To test the jam, place a small spoonful on a cold plate.
Let it sit for a minute, then run your finger through it. If it holds its shape and wrinkles slightly, it is ready.
If it is still too runny, cook for a few more minutes and test again.
Step 6: Fill the Jars
Carefully spoon or pour the hot jam into clean, sterilized jars.
Seal tightly and let the jars cool at room temperature.
Once cooled, store in the refrigerator.
Tips for the Best Rhubarb Jam
Use fresh, firm rhubarb for the best texture and flavor.
Chop the rhubarb evenly so it cooks at the same rate.
Stir often while cooking to prevent sticking or burning.
Do not rush the cooking process. The jam needs time to thicken.
Use a large pot because jam can bubble up as it boils.
For a smoother jam, cook a little longer or mash the rhubarb as it softens.
For a chunkier jam, stop cooking once the rhubarb is soft but still has some texture.
Variations
Strawberry Rhubarb Jam
Replace 1 cup of rhubarb with 1 cup of chopped strawberries for a classic sweet-tart combination.
Orange Rhubarb Jam
Add 1 teaspoon orange zest for a bright citrus flavor.
Vanilla Rhubarb Jam
Stir in ½ teaspoon vanilla extract after removing the jam from the heat.
Ginger Rhubarb Jam
Add ½ teaspoon fresh grated ginger for a warm, slightly spicy flavor.
Raspberry Rhubarb Jam
Add 1 cup raspberries for a deeper fruity flavor and beautiful color.

Storage Instructions
Store rhubarb jam in clean sealed jars in the refrigerator for up to 2–3 weeks.
For longer storage, freeze the jam in freezer-safe jars or containers for up to 3 months.
Leave a little space at the top of the container before freezing because jam expands as it freezes.
Thaw overnight in the refrigerator before using.
For shelf-stable storage, use a proper tested canning method and process the jars according to safe home canning guidelines.
Frequently Asked Questions
Can I use frozen rhubarb?
Yes. Frozen rhubarb works well. Thaw it first and drain off excess liquid before cooking.
Can I make rhubarb jam without pectin?
Yes, but it will take longer to thicken and may have a softer set. Pectin makes the process quicker and more reliable.
Why is my rhubarb jam runny?
It may need more cooking time, or the pectin may not have fully activated. Continue cooking for a few more minutes and test again.
Can I reduce the sugar?
You can reduce it slightly, but sugar helps the jam set and balances rhubarb’s tart flavor. If reducing sugar a lot, use a low-sugar pectin.
Is rhubarb a fruit or vegetable?
Rhubarb is technically a vegetable, but it is usually used like a fruit in jams, pies, crisps, and desserts.
Can I double the recipe?
Yes, but larger batches may take longer to thicken. For best results, make smaller batches.
