The Best Strawberry Rhubarb Jam Recipe
When it comes to homemade preserves, strawberry rhubarb jam stands out with its vibrant color and tantalizing taste. The combination of juicy strawberries and tart rhubarb creates a flavor explosion that’s perfect for any time of year. Plus, it’s a great way to preserve seasonal fruits!
Ingredients for Perfect Strawberry Rhubarb Jam
Selecting Your Rhubarb and Strawberries
To make the best jam, start with fresh, young rhubarb and ripe strawberries. Look for plump berries without soft spots. Tender rhubarb stalks ensure a smoother texture, while vibrant color indicates freshness.
Essential Sweeteners and Acidity
You’ll need 6 cups of diced rhubarb and 3 cups of diced strawberries, which will create a beautiful balance of flavors. The 2 cups of granulated sugar help preserve the jam and enhance sweetness. Don’t forget the ¼ cup of lemon juice, as it balances the sweetness and adds necessary acidity!
Step-by-Step Guide to Making Strawberry Rhubarb Jam
Preparing Your Fruit and Equipment
Begin by preparing your rhubarb: trim the leaves, wash the stalks thoroughly, and dice them into ½” pieces. You should end up with about 6 cups. Then, wash and hull your strawberries, removing any brown spots, and dice them to yield 3 cups. While you’re at it, gather your canning supplies and place small plates in the freezer for testing consistency later.
Cooking Down the Fruit Mixture
In a large pot, combine your diced rhubarb, strawberries, sugar, and ½ cup of water. Cook over medium-high heat, stirring frequently. After about 10-15 minutes, the juices will cover the fruit, creating a fragrant mixture.
Reducing the Juice for a Thick Jam
Next, pour the mixture into a colander set over a large bowl to strain out the juice. Save the pulp and any additional juice collected in the bowl. Return the juice to the pot and boil it over high heat, stirring occasionally until it reduces to about 1½ cups, which will take approximately 20 minutes.
The Crucial Gel Test
Once the juice is reduced, add the reserved fruit pulp and lemon juice back into the pot. Bring to a simmer and continue to cook for about 15 minutes, stirring frequently. To test for gel, use the cold plate method: drop a spoonful of the jam onto a chilled plate. If it runs, cook for another 5 minutes and test again until it reaches the desired thickness.
Finishing and Skimming Your Jam

After ensuring your jam has reached the right consistency, skim off any foam that has formed on the top. Stir gently for one minute to distribute the fruit evenly throughout the mixture before ladling it into hot jars.
Canning Your Strawberry Rhubarb Jam for Preservation
Water Bath Canning Process
Leave ¼” headspace in the jars and wipe the rims clean before applying the lids. Process the jars in a water bath canner for 10 minutes, or 15 minutes if you are above 6,000 feet in elevation. This ensures your jam is safe and well-preserved.
Elevation Adjustments for Canning
Remember to adjust your canning time based on your elevation. This small step is vital for ensuring that your jam is shelf-stable and delicious.
Alternative Refrigerator Storage
If you prefer to skip canning, simply ladle the jam into containers and refrigerate it once it cools. It will keep well in the refrigerator for several weeks, making it a great snack option!
