Why You Will Love This Recipe
This recipe is incredibly popular for several key reasons. First and foremost, it is genuinely easy, making it accessible even if you’ve never canned before. The inclusion of pectin ensures a reliable set every time, minimizing the guesswork often associated with fruit preserves. Secondly, the quintessential pairing of sweet strawberries with tangy rhubarb creates a balanced flavor profile that is brighter and more complex than strawberry jam alone. Finally, making this jam allows you to preserve the fresh flavors of late spring and early summer to enjoy all year long, reducing food waste and saving money on store-bought jams.
Ingredients
- 4 cups sliced, fresh or frozen rhubarb (about 1 pound)
- 4 cups crushed, fresh or frozen strawberries (about 2 pounds)
- 6 cups granulated sugar
- 1 package (1.75 oz) powdered fruit pectin
- 1 tablespoon lemon juice (optional, for brightness and pH balance)
Step-by-Step Instructions
- Prepare your canning station: Sterilize your jars, lids, and rings according to standard safe canning practices. Keep jars hot until ready to fill.
- Combine the fruit: In a large, heavy-bottomed pot, combine the crushed strawberries and the sliced rhubarb. Cook over medium heat, stirring occasionally, until the fruit has softened and released plenty of juice (about 10-15 minutes).
- Add sugar and pectin: Measure the granulated sugar and the powdered pectin into a separate bowl and whisk them together briefly to prevent clumping.
- Boil the mixture: Add the sugar/pectin mixture to the fruit in the pot. Stir vigorously until the sugar is completely dissolved.
- Achieve a rolling boil: Increase the heat to high and bring the mixture to a full, rolling boil that cannot be stirred down. Boil hard for exactly 1 minute, stirring constantly to prevent scorching. If using, stir in the lemon juice during this final minute of boiling.
- Skim foam (optional): Remove the pot from the heat. Carefully skim off any foam that has accumulated on the surface using a long-handled spoon.
- Fill the jars: Ladle the hot jam immediately into the hot, sterilized jars, leaving 1/4 inch headspace at the top. Wipe the rims clean with a damp cloth. Center the lids and screw on the bands until “fingertip tight.”
- Process the jars: Place the filled jars into a boiling water canner, ensuring they are covered by at least 1 inch of water. Bring the water to a full, rolling boil, cover the canner, and process for 10 minutes (adjusting time for altitude if necessary).
- Cool and seal: Carefully remove the jars and place them on a towel-lined counter, away from drafts. Allow them to cool undisturbed for 12 to 24 hours. Check seals; properly sealed jars will have concave lids that do not move when pressed.
Expert Tips / Pro Tips
To ensure the absolute best results for your Easy Strawberry Rhubarb Jam with Pectin, keep these expert tips in mind.
Mashing Consistency: If you prefer a smoother jam, use an immersion blender to briefly pulse the fruit mixture once it has softened but BEFORE adding the sugar and pectin. A few quick pulses are enough; don’t completely purée it.
Measuring Pectin: Always follow the package directions for the pectin exactly. Pectin is usually measured by weight or the lines on the packet; using too much can result in a gummy texture, while too little will prevent proper setting.
The Rolling Boil Test: The boil must be high and sustained for the full minute specified. If your pot is very large and the heat is high, the foam-up can happen quickly. Have your lids ready right next to the stove, as speed is essential once the jam is finished boiling.
Altitude Adjustment: If you live above 1,000 feet elevation, you must increase the processing time in the water bath. Check specific USDA guidelines for your altitude, usually adding 5 minutes for every 1,000 feet above sea level.
Variations & Substitutions
While the classic combination is unbeatable, feel free to experiment with these delicious twists:
- Spice it Up: Add 1/4 teaspoon of ground cinnamon or 1/2 teaspoon of finely grated fresh ginger to the pot when you add the sugar. This introduces a wonderful warmth to the tart rhubarb.
- Vanilla Bean: For a more complex, aromatic jam, scrape the seeds from half a vanilla bean and cook them in with the fruit. Remove the pod before filling the jars.
- Rhubarb Swap: If strawberries are out of season, you can achieve a similar tartness by substituting equal parts tart cherries or raspberries. Minor adjustments to the pectin amount might be necessary depending on the natural pectin content of the substitute fruit; consult your pectin package for guidance.
Serving Suggestions
This bright, versatile jam is perfect for far more than just toast!
- Spread generously over homemade biscuits, scones, or English muffins.
- Use as a filling layer in layer cakes or between macaron shells.
- Swirl into plain Greek yogurt or cottage cheese for a vitamin-packed breakfast.
- Serve alongside a cheese board featuring mild goat cheese or sharp cheddar.
- Warm it slightly and drizzle over vanilla bean ice cream or pound cake.
Storage, Freezing & Reheating
Proper storage is key to enjoying your labor of love safely.
Canned Shelf Life: When properly processed and sealed using the boiling water bath method described above, this Easy Strawberry Rhubarb Jam with Pectin is shelf-stable for up to one year in a cool, dark pantry. Always check that the seal is intact before opening.
Refrigeration: Once opened, the jar must be stored in the refrigerator and consumed within 3 to 4 weeks.
Freezing: If you choose not to can, you can freeze the jam. Ladle the cooled jam into freezer-safe containers (leaving at least 1/2 inch of headspace) and freeze for up to 6 months. Thaw overnight in the refrigerator before use.

FAQ
Why is my jam the consistency of syrup and not setting?
If your jam did not set properly after cooling, the most common reasons are: insufficient boiling time (it must reach a full rolling boil for the specified time), not enough pectin for the amount of fruit/sugar used, or not enough acid (lemon juice). For jams made without commercial pectin, it often means the fruit wasn’t cooked long enough to concentrate the natural pectin.
Can I use low-sugar pectin for this recipe?
No, standard recipes using traditional granulated sugar and commercially packaged powdered pectin are specifically balanced for that type of pectin. Low-sugar or no-sugar pectin requires different ratios of fruit and added sweetener, and substituting it directly will likely result in a thin jam.
Do I really need to sterilize the jars for this recipe?
Yes, sterilization is crucial when water bath canning, especially for recipes like this that process for 10 minutes or less. Sterilizing ensures that any surface bacteria or wild yeasts are killed, preventing spoilage and ensuring a safe seal. Always keep your jars hot right up until the moment you fill them with hot jam.
How do I know when the fruit is soft enough before adding pectin?
The fruit should reach a gentle simmer and be easily pierced with a fork, having released a significant amount of liquid. For strawberries, this means they have lost their bright, firm shape and are softened but not yet fully broken down into mush.
Easy Strawberry Rhubarb Jam with Pectin
Ingredients
Method
- Prepare your canning station: Sterilize jars and keep them hot, and prepare the lids according to the manufacturer’s directions.
- Combine the prepared rhubarb and strawberries in a large, heavy-bottomed pot or Dutch oven. Cook over medium heat, stirring occasionally, until the fruit begins to release its juices and softens, about 10-12 minutes.
- Increase the heat to high. In a separate small bowl, thoroughly mix the granulated sugar with the entire package of powdered pectin. Sprinkle this sugar-pectin mixture over the hot fruit while stirring constantly to prevent the pectin from clumping.
- Bring the mixture to a full, rolling boil that cannot be stirred down. Once boiling, add the optional butter to dissipate foam. Boil hard for exactly 1 minute, stirring constantly. Remove from heat immediately.
- Carefully skim off any surface foam using a long-handled spoon. Ladle the hot jam into the sterilized jars, leaving 1/4 inch headspace. Wipe rims clean and affix lids and bands fingertip tight.
- Process the jars in a boiling water canner for 10 minutes (adjusting time for altitude if necessary). Turn off the heat, let the jars rest in the hot water for 5 minutes, then remove to a towel-lined counter to cool completely for 12-24 hours before checking seals.
