If you love cinnamon-forward treats, you’ll also enjoy the texture contrast in these cinnamon-sugar blondies, which pair beautifully with a dollop of jam. Read on for a simple, dependable recipe and helpful tips for turning fresh rhubarb into golden jars of cinnamon-scented goodness.
Ingredients & Equipment
Ingredients
- 4 cups rhubarb, chopped
- 1 cup sugar
- 1/4 cup water
- 1 teaspoon ground cinnamon
- 1 tablespoon lemon juice
- 1 package pectin
Notes
- Use crisp, fresh rhubarb stalks; discard any leaves (they are not used in cooking).
- Adjust sugar to taste if you prefer a tarter or sweeter jam, but remember sugar helps with gelling and preservation.
- If you prefer a less textured jam, you can pulse the cooked rhubarb lightly with a blender or immersion blender.
Helpful equipment
- Large, heavy-bottomed pot (for even heating)
- Wooden spoon or heatproof spatula
- Sterilized canning jars with lids and bands
- Ladle and funnel (useful for filling jars)
- Blender or immersion blender (optional, for smoother jam)
- Baking tray (useful if you roast the rhubarb as a variation)
- Candy or jam thermometer (optional but helpful to check temperature for gelling)
- Large bowl of ice water (for cooling utensils and testing gelling)
If you enjoy making pantry staples alongside drinks and elixirs, this jam pairs nicely with a morning jar of seasonal blends like the one described in seasonal homemade elixirs.
Step-by-Step Instructions (with tips)
Below is a straightforward method that follows the classic stovetop approach, plus variations and tips to help you tailor the jam to your taste and kitchen style.
- Prepare the rhubarb
- Trim and wash the rhubarb stalks, then chop them into 1/2- to 1-inch pieces so they cook evenly. Measure 4 cups once chopped.
- Combine rhubarb, sugar, and water
- In a large pot, combine the chopped rhubarb, 1 cup sugar, and 1/4 cup water. Stir to distribute the sugar and let the mixture sit for 10–15 minutes if you have time; this maceration step helps draw moisture out and shortens cooking time.
Tip: Use a heavy-bottomed pot to prevent scorching. If your rhubarb is very dry, add an extra tablespoon or two of water.
- Cook until soft
- Cook over medium heat, stirring occasionally, until the rhubarb is soft and breaking down (about 8–12 minutes). Reduce heat if the mixture splatters.
Tip: If you prefer a chunkier jam, cook until the pieces are just soft. For a smoother jam, cook a bit longer or blend briefly with an immersion blender.
- Add cinnamon and lemon juice
- Once the rhubarb is soft, add 1 teaspoon ground cinnamon and 1 tablespoon lemon juice, stirring well to incorporate. The lemon juice brightens the flavor and helps the pectin set.
- Bring to a boil and add pectin
- Increase heat to bring the mixture to a rolling boil. Quickly stir in the package of pectin, mixing thoroughly to avoid lumps.
Tip: If using powdered pectin, sprinkle it evenly and stir continuously. Liquid pectin can be added according to package directions; follow the manufacturer’s instructions for timing.
- Boil for 1–2 minutes while stirring constantly
- Continue boiling for 1–2 minutes, stirring constantly to prevent sticking. The jam should thicken slightly and the surface will become glossy.
Safety tip: Hot sugar mixtures are very hot—use long sleeves and be careful when stirring.
- Remove from heat and let cool briefly
- Turn off the heat and let the jam cool for 3–5 minutes to allow bubbles to settle before jarring.
- Fill sterilized jars and seal
- Using a ladle and funnel, pour the jam into sterilized jars, leaving about 1/4 inch headspace. Wipe rim, apply lids and rings, and seal.
- Cool completely before storing
- Allow jars to cool completely on a towel or cooling rack. Once cooled, check seals and store in the refrigerator for immediate use or process in a water bath for longer shelf life (see storage section).
Variations and flavor tweaks
- Roasted rhubarb variation: Toss chopped rhubarb with a bit of sugar and roast at 375°F (190°C) on a baking tray for 12–15 minutes until softened and slightly caramelized. Transfer to a pot, add cinnamon, lemon juice, and pectin, then proceed with the recipe. Roasting intensifies the rhubarb’s flavor and adds depth.
- Lower-sugar option: Use a low-sugar pectin and follow package directions; you can reduce sugar but texture may differ.
- Spiced twist: Add 1/4 teaspoon ground cardamom or a small split vanilla bean for another aromatic layer.
- Citrus variation: Substitute half the lemon juice with orange juice for a sweeter, citrus note.
Kitchen tips
- To test for set without a thermometer, spoon a small amount of jam onto a cold plate; if it wrinkles when pushed with your finger after a minute, it’s ready.
- If foam forms, skim it off with a spoon for clearer jars.
- Label jars with the date so you know how long they’ve been stored.
Storage, Freezing & Make-Ahead Tips
Refrigerator storage
- Fresh, sealed jam stored in sterilized jars and kept in the refrigerator should last about 3–4 weeks after opening. If you’re not processing jars in a water bath, keep them refrigerated and use within this window.
Water-bath canning (for shelf-stable jars)
- If you’d like shelf-stable jars to sit in your pantry, process the filled and sealed jars in a boiling water bath for 10 minutes (adjust time for altitude). Make sure jar seals are secure before storing. Properly processed jars can last up to 12–18 months in a cool, dark pantry.
Freezing jam
- Jam freezes well. Leave 1/2-inch headspace in freezer-safe containers to allow expansion. Frozen jam can last up to 12 months; thaw in the refrigerator overnight before using.
Make-ahead and gifting
- Rhubarb Cinnamon Jam makes lovely gifts. Sterilize jars in advance, prepare gift labels, and include suggestions for serving. For a make-ahead breakfast prep, portion jam into small jars so you have grab-and-go toppings for toast, yogurt, or pastries.
Portioning tips
- Consider dividing the batch into one large jar for home use and several smaller jars for gifts or single-serving portions. This reduces waste and keeps opened jars fresher longer.
How to Use / Serve This Dish
Classic uses
- Spread on morning toast, English muffins, or scones for a bright, cinnamon-kissed start to the day.
- Swirl into plain yogurt or cottage cheese for a fruity, spiced breakfast bowl.

- Offer small jars at a brunch spread so guests can sample and take home a jar as a favor.
FAQ
Q: Can I make this jam without pectin?
A: Yes. You can make a pectin-free rhubarb jam, but you’ll need to cook the fruit longer to concentrate the natural pectins and sugars. Expect a looser set and a deeper, more caramelized flavor. For a firmer set without commercial pectin, combine rhubarb with a higher-pectin fruit (like apple) or use a longer reduction time, testing on a chilled plate.
Q: Can I reduce the sugar or use a sugar substitute?
A: You can reduce sugar, but sugar affects both preservation and texture. Using less sugar may result in a softer set unless you use low-sugar pectin specifically designed for that purpose. Natural sweeteners like honey or date syrup can alter flavor and texture; if substituting, experiment with small batches first. Always follow the pectin manufacturer’s guidance for sugar ratios.
Q: How long will this jam last unopened and opened?
A: Properly processed and sealed jars stored in a cool, dark place can last up to 12–18 months. Once opened, refrigerate and use within 3–4 weeks for best quality. If you freeze jam, expect up to 12 months of storage time.
Q: My jam is too runny—what can I do?
A: If the jam is too runny, you can return it to the pot and simmer to reduce and thicken, or add a small amount of dissolved pectin following package instructions. Remember to test the set on a chilled plate as you go to avoid overcooking.
Final Thoughts & Tips
- Taste and adjust: Rhubarb varies in tartness year to year. Taste your cooked mixture before adding pectin and adjust sugar or lemon as needed.
- Safety first: Always sterilize jars and follow canning guidelines if you want shelf-stable storage.
- Keep experimenting: Once you have the base recipe down, try adding different warming spices, citrus zests, or mixing in other fruits like strawberries for a rhubarb-strawberry-cinnamon jam.
