Homemade Rhubarb Jam with a Hint of Cinnamon
This easy homemade rhubarb jam is bright, tangy, and kissed with warm cinnamon spice. A rustic rhubarb preserve perfect for spreading, gifting, or canning.
The Jar of Spring You Will Want to Make Every Year
If you have ever stood in the produce section staring at those bold red-green stalks wondering what on earth to do with them, this recipe is your answer. This homemade rhubarb jam is one of those preserves that genuinely surprises people. It is tart, fragrant, a little complex, and so much more interesting than store-bought fruit spreads. Slather it on sourdough toast, swirl it into yogurt, spoon it over vanilla ice cream, or tuck a jar into a gift basket. It earns its place in any kitchen.
The touch of cinnamon here is deliberate but not overpowering. It rounds out the sharpness of the rhubarb in the way a pinch of salt rounds out sweetness, you do not taste cinnamon exactly, you just taste depth. That is the secret behind a great cinnamon rhubarb preserve.
Why This Easy Rhubarb Jam Tutorial Works So Well
Many rhubarb jam recipes lean heavily on commercial pectin, but rhubarb is naturally rich enough in pectin that all it really needs is time, sugar, and a little lemon. This approach, made famous by preserving experts like Pam Corbin in her celebrated jam-making guides, trusts the fruit to do its own work. The result is a more honest, fruit-forward preserve.
Here is what makes this recipe stand out:
- No commercial pectin required. The natural pectin in rhubarb sets the jam beautifully.
- Simple, pantry-friendly ingredients. You likely have everything except the rhubarb already.
- Flexible texture. Blend it smooth or leave it chunky and rustic. Both are wonderful.
- Canning-ready. This recipe follows safe water bath canning guidelines for shelf-stable jars.
Chef's Tip: Always discard rhubarb leaves before cooking. They contain oxalic acid and are toxic. Only the stalks are used in cooking.
The Right Tools Make a Real Difference
For jam-making, a heavy-bottomed saucepan or enameled Dutch oven is genuinely worth having. Thin pans scorch sugar easily, and once jam burns it cannot be saved. A reliable canning funnel and a set of proper mason jars also take the stress out of the raspberry rhubarb jam canning process entirely.
How To Make Rhubarb Jam: The Process
The homemade rhubarb jam process is more forgiving than most people expect. The biggest key is patience during the cook-down phase. Here is what to watch for:
Macerating the rhubarb first by tossing it with sugar and letting it rest for 15 minutes draws out the juices naturally. This gives you a head start and means you rarely need to add water.
Color shifts are your guide. The mixture starts out pale pink or pale green depending on your rhubarb variety and deepens to a rich rosy color as it cooks. That color shift signals that the sugars are concentrating properly.
The wrinkle test is non-negotiable. Before you call the jam done, drop a small spoonful on a chilled plate, wait 30 seconds, and push it with your finger. If it wrinkles and holds shape, you have a set. If it runs, give it another 5 minutes.
Chef's Tip: For a cinnamon rhubarb butter consistency, blend the finished jam completely smooth with an immersion blender and cook an extra 10 to 15 minutes. The texture becomes dense, silky, and even more spreadable.

Homemade Rhubarb Jam with a Hint of Cinnamon
This easy homemade rhubarb jam is bright, tangy, and kissed with warm cinnamon spice. A rustic rhubarb preserve perfect for spreading, gifting, or canning.
Ingredients
- 2 lb rhubarb stalks, trimmed and cut into 0.5-inch pieces, leaves discarded
- 2 cups granulated white sugar, adjust to taste depending on rhubarb tartness
- 2 tbsp fresh lemon juice, freshly squeezed, not bottled
- 1 tsp lemon zest, from about half a lemon
- 1/2 tsp ground cinnamon, use up to 1 tsp for a stronger warmth
- 1/2 tsp vanilla extract, pure, not imitation
- 1/4 cup water, only if rhubarb is very dry
Instruction
Wash and trim the rhubarb stalks, discarding any leaves entirely as they are toxic. Cut the stalks into roughly 0.5-inch pieces and add them to a large heavy-bottomed saucepan.
Pour the sugar over the rhubarb, add the lemon juice and lemon zest, then stir everything together. Let the mixture sit for 10 to 15 minutes so the sugar begins to draw out the natural juices from the rhubarb.
Place the saucepan over medium heat. Stir gently and bring the mixture to a steady simmer. If the rhubarb looks very dry after resting, add the 0.25 cup of water now.
Once simmering, reduce the heat to medium-low and cook uncovered for 25 to 35 minutes, stirring frequently. The rhubarb will completely break down and the mixture will thicken noticeably.
Stir in the ground cinnamon and vanilla extract. Taste the jam and adjust sugar or cinnamon to your preference.
To test for doneness, place a small spoonful of jam on a chilled plate and push it with your finger. If it wrinkles and holds its shape rather than running, the jam is ready.
Remove the pan from heat. For a smooth jam, use an immersion blender or mash with a fork for a chunkier rustic texture.
For immediate use, let the jam cool completely and transfer it to a clean jar. Refrigerate and use within 3 weeks. For canning, ladle the hot jam into sterilized half-pint jars leaving 0.25-inch headspace, wipe the rims, apply lids, and process in a boiling water bath for 10 minutes.
Equipment
- Large heavy-bottomed saucepan or Dutch oven
- Wooden spoon or silicone spatula
- Citrus zester or microplane
- Immersion blender (optional, for smooth jam)
- Chilled plate (for jam set test)
- Sterilized half-pint mason jars with lids (for canning)
- Ladle
- Canning funnel (optional but helpful)
- Large stockpot with rack (for water bath canning)
Notes
Serving Ideas, Variations, and Storage
Once your jam has cooled, the possibilities open up fast. Some favorites:
- On toast or biscuits with a little salted butter underneath
- Stirred into oatmeal or overnight oats in the morning
- As a glaze brushed over roasted pork tenderloin or duck breast
- Layered into a Victoria sponge or thumbprint cookies
- Swirled into cream cheese for a quick and impressive appetizer spread
For a raspberry rhubarb jam canning variation, replace half a pound of rhubarb with fresh or frozen raspberries. The flavor becomes more floral and the color turns a gorgeous deep magenta.
Refrigerated jam keeps for up to 3 weeks. Properly canned and sealed jars are shelf-stable for 12 months, making this an ideal recipe to batch-cook in late spring when rhubarb is at its peak.
