When the first stalks of spring rhubarb emerge from the garden, most people immediately think of strawberry rhubarb pie. However, there is a hidden gem in the world of preserves that deserves your attention: rhubarb cinnamon jam. This recipe takes the aggressive tartness of fresh rhubarb and marries it beautifully with the warm, woody depth of cinnamon. The result is a sophisticated, ruby-red spread that feels both nostalgic and refreshing. Whether you are a seasoned canner or a novice in the kitchen, this small-batch preserve will transform your morning toast into a gourmet experience.
Why This Recipe Works
This rhubarb cinnamon jam recipe is a favorite for several reasons. First, it relies on the natural pectin found in rhubarb and the thickening power of sugar, meaning you don’t necessarily need store-bought pectin to get a great set. The acidity of the lemon juice balances the sugar, ensuring the jam isn’t cloyingly sweet.
Furthermore, the addition of cinnamon adds a layer of complexity that you don’t get in standard fruit jams. While many fruit preserves are one-note, the spice here provides a long finish that pairs exceptionally well with savory elements like cheese or fatty meats. It is an excellent way to preserve the fleeting rhubarb season so you can enjoy these vibrant flavors well into the autumn months.

Ingredients
To create the perfect batch of rhubarb cinnamon jam, you will need high-quality ingredients. Fresh rhubarb is preferred, but frozen will work in a pinch.
- Rhubarb: 2 lbs of fresh stalks, trimmed and chopped into 1/2-inch pieces.
- Granulated Sugar: 3 cups to provide sweetness and help the jam set.
- Lemon Juice: 2 tablespoons of fresh juice for acidity.
- Ground Cinnamon: 1.5 teaspoons for that signature warmth.
- Cinnamon Stick: 1 whole stick to infuse deeper flavor during the boil.
- Vanilla Extract: 1 teaspoon to round out the flavors (optional).
Equipment
Proper equipment ensures that your rhubarb cinnamon jam reaches the correct temperature and sets perfectly without scorching.
- Heavy-Bottomed Pot: A Dutch oven or a heavy stainless steel pot is essential to prevent burning.
- Wooden Spoon: For constant stirring.
- Glass Jars: Sterilized Mason jars with new lids and rings.
- Candy Thermometer: To ensure you reach the “gel point” of 220°F (104°C).
- Jar Funnel: To minimize mess when transferring the hot jam.
Step by Step Guide
Follow these steps carefully to achieve a perfect rhubarb cinnamon jam consistency.
Step 1: Macerate the Rhubarb
In a large bowl, combine your chopped rhubarb and sugar. Stir well until the rhubarb is completely coated. Let this sit at room temperature for at least 2 hours (or overnight in the fridge). This process draws out the liquid from the rhubarb, creating a natural syrup and helping the fruit retain its shape.
Step 2: Prepare the Infusion
Transfer the rhubarb and its accumulated juices into your heavy-bottomed pot. Add the lemon juice, ground cinnamon, and the cinnamon stick. Stir to combine and place over medium heat.
Step 3: The Rolling Boil
Bring the mixture to a boil, stirring frequently. Once it reaches a boil, increase the heat slightly. You want a “rolling boil”—one that doesn’t stop when you stir it. Use your wooden spoon to mash any large chunks of rhubarb against the side of the pot if you prefer a smoother jam.
Step 4: Reaching the Set Point
Continue to cook the rhubarb cinnamon jam until it thickens. This usually takes 15–20 minutes. Use a candy thermometer to check for 220°F. If you don’t have a thermometer, place a small plate in the freezer. Drop a spoonful of jam onto the cold plate, let it sit for 30 seconds, and push it with your finger. If it wrinkles, it is ready.
Step 5: Finishing Touches
Remove the pot from the heat. Carefully remove and discard the cinnamon stick. Stir in the vanilla extract if using. Skim off any foam that has collected on the surface with a metal spoon.
Step 6: Jarring
Ladle the hot rhubarb cinnamon jam into sterilized jars, leaving about 1/4 inch of headspace. Wipe the rims clean, apply the lids, and tighten the rings. You can process these in a water bath for 10 minutes for long-term shelf storage or simply let them cool and store them in the refrigerator for up to a month.
To Incorporate With
The versatility of rhubarb cinnamon jam is surprising. While it is a staple for breakfast, its flavor profile allows for much more. Consider these pairings:
- Fresh Scones: Serve with clotted cream and a dollop of jam for a classic tea time.
- Yogurt Parfaits: Swirl the jam into Greek yogurt with granola.
- Cheese Boards: It pairs beautifully with sharp cheddar or creamy brie.
- Glaze for Pork: Thin the jam with a little apple cider vinegar to use as a glaze for roasted pork tenderloin.
- Oatmeal: A spoonful of this spiced preserve adds instant life to a bowl of steel-cut oats.
Varieties / Substitutions
You can easily customize your rhubarb cinnamon jam to suit your preferences. If you find rhubarb too tart, you can replace 1/4 of the rhubarb with peeled, diced apples, which naturally contain high pectin. For a deeper flavor, use brown sugar for half of the granulated sugar requirements; this creates a caramel-like undertone that complements the cinnamon perfectly. If you want a punchier spice profile, add 1/2 teaspoon of grated fresh ginger or a pinch of ground cloves. For more information on different fruit varieties, visit this external link.
Tips for Success
To ensure your rhubarb cinnamon jam turns out perfectly every time, keep these tips in mind. Always use a pot that is larger than you think you need, as the jam can bubble up significantly during the boiling phase. Don’t skip the lemon juice; it’s not just for flavor, it’s essential for the chemistry of the pectin set. If your jam feels too thick after cooling, you can stir in a teaspoon of warm water before serving to loosen it up. Finally, remember that jam continues to firm up as it cools in the jar, so don’t overcook it past the wrinkle test stage.
10 FAQ
1. Can I use frozen rhubarb? Yes, but let it thaw and drain some of the excess water first so the jam doesn’t become too runny.
2. Why is my jam runny? It likely didn’t reach the 220°F set point or lacked enough sugar/acid to activate the natural pectin.
3. Can I reduce the sugar? Sugar is essential for preservation and setting. Reducing it significantly may result in a sauce rather than a jam.
4. How long does this jam last? If water-bath canned, it lasts 1 year. If refrigerated, it lasts about 3-4 weeks.
5. Is rhubarb toxic? Only the leaves are toxic due to high oxalic acid. The stalks are perfectly safe to eat.
6. Can I make this without cinnamon? Certainly, though it will change the flavor profile to a standard rhubarb jam.
7. Do I need to peel the rhubarb? No, the skin provides the beautiful pink color and softens during cooking.
8. What if I don’t have a thermometer? Use the “cold plate test” mentioned in the step-by-step guide.
9. Can I add pectin? If you want a very firm set or a shorter cooking time, you can add liquid or powdered pectin following the manufacturer’s instructions.
10. Why did my jam turn brown? This is usually due to overcooking the sugar or using too much ground cinnamon. It is still safe to eat!
