When the first stalks of bright pink rhubarb emerge in the garden, it is a signal that spring has truly arrived. While many people immediately reach for strawberries to pair with this tart vegetable, there is a hidden gem of a combination that often goes overlooked: Rhubarb Cinnamon Jam. This preserve offers a sophisticated depth of flavor that balances the sharp, acidic bite of rhubarb with the warm, woody notes of ground cinnamon. It is a cozy, comforting spread that feels just as appropriate on a cold autumn morning as it does during a breezy spring brunch. Making your own Rhubarb Cinnamon Jam is a rewarding process that fills your kitchen with an aroma that is nothing short of heavenly.
Why This Recipe Works
This Rhubarb Cinnamon Jam recipe works so well because it relies on the natural chemistry of its ingredients to create a perfect set and a balanced profile. Rhubarb is naturally high in acid, which is essential for the pectin to do its job, even if we are not adding commercial pectin to this particular version. By macerating the rhubarb in sugar first, we draw out the natural juices, creating a thick syrup that cooks down into a luscious, jammy consistency.
The addition of cinnamon is the “secret weapon” here. While rhubarb is famously tart, the cinnamon provides a grounding earthiness that cuts through the sharpness without requiring an overwhelming amount of sugar. This creates a more complex flavor than your standard fruit jam. Furthermore, this recipe is designed for small-batch canning, making it accessible for beginners who might be intimidated by large-scale preserving projects.

Ingredients
To create the perfect batch of Rhubarb Cinnamon Jam, you will need the following high-quality ingredients:
- Fresh Rhubarb: Look for firm, bright red stalks for the best color, though green stalks work just as well for flavor. You will need about 2 pounds (roughly 6-8 cups chopped).
- Granulated Sugar: This acts as the preservative and sweetener. We use 3 cups to ensure a good set.
- Lemon Juice: 2 tablespoons of fresh lemon juice adds necessary acidity and extra natural pectin.
- Ground Cinnamon: 1 to 2 teaspoons, depending on how prominent you want the spice to be.
- Vanilla Extract (Optional): A splash of vanilla adds a creamy finish to the Rhubarb Cinnamon Jam.
- Butter (Optional): A tiny half-teaspoon can help reduce foaming during the boiling process.
Equipment
Having the right tools is half the battle when it comes to successful jam making. For this Rhubarb Cinnamon Jam, gather the following:
- Heavy-Bottomed Pot: A stainless steel or copper pot is ideal to prevent scorching.
- Wooden Spoon or Silicone Spatula: For constant stirring.
- Canning Jars: 4 to 5 half-pint jars with fresh lids and bands.
- Jar Lifter and Funnel: Essential for safety when handling hot glass.
- Candy Thermometer: To check for the “gel point” (usually 220°F or 104°C).
- Large Pot: If you plan on processing the jars in a water bath for long-term storage.
Step by Step Guide
Following these steps carefully will ensure your Rhubarb Cinnamon Jam reaches the perfect consistency every time.
Step 1: Preparation and Maceration
Wash your rhubarb stalks thoroughly and trim off any leaves (remember, rhubarb leaves are toxic and should never be eaten). Slice the stalks into small, 1/2-inch pieces. In a large non-reactive bowl, combine the chopped rhubarb and the sugar. Toss them well and let the mixture sit for at least 2 to 4 hours, or even overnight in the refrigerator. This maceration process creates the syrup base for your Rhubarb Cinnamon Jam.
Step 2: Sterilize Your Jars
While the rhubarb is finishing its maceration, wash your jars and lids in hot, soapy water. Keep the jars warm in a low oven or a pot of hot water until you are ready to fill them. This prevents the glass from cracking when the hot jam is added.
Step 3: Cooking the Jam
Transfer the rhubarb and sugar mixture into your heavy-bottomed pot. Add the lemon juice and ground cinnamon. Turn the heat to medium-low and stir until the sugar is completely dissolved. Once dissolved, increase the heat to medium-high and bring the mixture to a rolling boil.
Step 4: Reaching the Gel Point
Stir frequently to prevent the bottom from burning. The jam will foam up initially; you can add a small pat of butter to reduce this. Continue boiling until the mixture thickens. Use a candy thermometer to monitor the temperature. Once it hits 220°F (104°C), your Rhubarb Cinnamon Jam is ready. Alternatively, use the “cold plate test”: place a small spoonful of jam on a chilled plate, wait 30 seconds, and push it with your finger. If it wrinkles, it is set.
Step 5: Jarring and Storage
Remove the pot from the heat and stir in the vanilla extract if using. Ladle the hot jam into your prepared jars, leaving about 1/4 inch of headspace. Wipe the rims clean, apply the lids, and screw on the bands until finger-tight. You can store these in the fridge for immediate use or process them in a boiling water bath for 10 minutes for shelf-stable storage.

To Incorporate With
Rhubarb Cinnamon Jam is incredibly versatile. Its unique flavor profile allows it to swing between sweet and savory applications with ease.
Breakfast Classics
The most obvious use for your Rhubarb Cinnamon Jam is atop a piece of buttered sourdough toast. However, it also works beautifully swirled into a bowl of warm oatmeal or Greek yogurt. The cinnamon notes pair exceptionally well with the nuttiness of granola.
Sweet Treats
Use this jam as a filling for thumbprint cookies or as a layer in a Victoria sponge cake. It is also an excellent topping for cheesecake, where the tartness of the rhubarb cuts through the heavy cream cheese perfectly.
Savory Pairings
Don’t limit your Rhubarb Cinnamon Jam to the dessert table! It makes a fantastic glaze for roasted pork tenderloin or grilled chicken. The acidity and spice act much like a chutney, providing a bright contrast to fatty meats. It is also a sophisticated addition to a charcuterie board, pairing particularly well with aged cheddar or creamy camembert.
Varieties / Substitutions
While the classic Rhubarb Cinnamon Jam is a winner, you can easily tweak the recipe to suit your preferences.
- Strawberry-Rhubarb Cinnamon: Replace half of the rhubarb with fresh strawberries for a sweeter, more traditional flavor.
- Ginger Twist: Add a tablespoon of freshly grated ginger or finely chopped candied ginger along with the cinnamon for extra zing.
- Honey Sweetened: You can replace half of the sugar with honey, though keep in mind that honey will change the flavor profile and may result in a softer set.
- Apple-Rhubarb: Add one finely chopped Granny Smith apple to the mix to increase the natural pectin and add a different texture.
Tips for Success
To ensure your Rhubarb Cinnamon Jam is the envy of the neighborhood, keep these professional tips in mind:
- Don’t Double the Batch: It is tempting to make a massive amount at once, but jam sets better in smaller batches. Large batches take longer to reach the gel point, which can lead to overcooked fruit and a darker, less fresh flavor.
- Use Fresh Spices: Ground cinnamon loses its potency over time. Ensure your cinnamon is fresh for that distinct warm aroma.
- Watch the Color: If you want a bright red jam, use only the red parts of the rhubarb stalks. If your rhubarb is green, the jam will be a brownish-amber color, which is still delicious but less visually striking.
- Constant Stirring: As the Rhubarb Cinnamon Jam thickens, it becomes more prone to sticking to the bottom. Stir constantly during the final stages of boiling.
10 FAQ
1. Can I use frozen rhubarb?
Yes! Frozen rhubarb works perfectly for Rhubarb Cinnamon Jam. Just make sure to thaw it first and include any liquid that leaches out during the thawing process.
2. Why didn’t my jam set?
If your jam is too runny, it likely didn’t reach the proper temperature (220°F) or lacked enough acid. You can try re-boiling it with a bit more lemon juice.
3. Can I reduce the sugar?
Sugar is essential for the preservation and setting of the jam. If you reduce it significantly, the jam may not set and will have a much shorter shelf life.
4. How long does the jam last?
Properly canned Rhubarb Cinnamon Jam lasts up to a year in a cool, dark place. Once opened, keep it in the fridge for up to 3 weeks.
5. Do I have to peel the rhubarb?
No, there is no need to peel rhubarb. The skin softens during cooking and provides the beautiful pink color.
6. Is rhubarb a fruit or a vegetable?
Botanically, it is a vegetable, but in the culinary world (especially in the US), it is legally classified and treated as a fruit.
7. My jam turned brown, is it safe?
Yes. Cinnamon naturally darkens the jam, and if you used green rhubarb stalks, a brownish hue is normal. Oxidation over time can also cause darkening.
8. Can I use cinnamon sticks instead of ground?
Yes, you can simmer the jam with 2 cinnamon sticks and remove them before jarring. This gives a more subtle flavor than ground cinnamon.
9. Can I make this without a thermometer?
Yes, using the “cold plate test” mentioned in the step-by-step guide is a reliable traditional method.
10. Can I use a sugar substitute like Stevia?
Standard sugar-free sweeteners don’t react the same way as sugar to create a gel. You would need to use a specific “low sugar” pectin product to achieve a good result with substitutes.
Conclusion
Mastering the art of Rhubarb Cinnamon Jam is a fantastic way to preserve the bounty of the season.
