Strawberry and Rhubarb Jam Ingredients
- Strawberries: I'm using fresh strawberries to make this strawberry rhubarb jam. Make sure to remove the stalks. You can also use frozen strawberries.
- Rhubarb: If you're using fresh rhubarb, be sure to remove and discard the leafy parts, and trim both ends. The leaves of rhubarb are not edible. You can also use frozen rhubarb, which comes already cut and trimmed.
- Sugar: Use granulated white sugar for this recipe. Sugar doesn't just sweeten the jam, it also helps set it and adds to the jam's shelf-life. It's crucial to use the proper amount of sugar when making jam so that it not only tastes as it should, but reaches the correct consistency and preserves well.
- Lemon Juice: Oooh, the flavor of lemon juice in this jam is just amazing! It adds a beautiful vibrant zing to the jam that is so rewarding. Use fresh lemon juice, not bottled!
Adding Extra Ingredients
For fun, I sometimes like to swap in other ingredients to vary the flavor of the jam. Try adding finely diced fresh ginger for a sharp flavor, rosewater for a floral sweetness, or vanilla bean paste for a touch of heavenly vanilla flavor. Use ½ teaspoon if adding rosewater or vanilla bean paste, or 1½ teaspoons if adding ginger.
How to Make Strawberry Rhubarb Jam
Step 1: Prepare the rhubarb by cutting off and discarding the leaves and trimming both ends. Never eat rhubarb leaves, they are not safe to eat. Rhubarb should be washed and stripped of any tough, stringy ribs using a paring knife. Forced rhubarb does not need peeling, generally. Thinly slice the rhubarb once it's prepared. You can also use frozen rhubarb, which may already come sliced.
Step 2: Remove the stems and roughly chop strawberries. You can use fresh or frozen strawberries.
Step 3: Once the fruits are prepared, add them to a large, heavy-bottom saucepan. Pour the sugar over the fruit and stir.
Isabel's Top Tip
At this point, you can begin the jam-making process, or refrigerate and let the jam develop flavors for up to 24 hours in the refrigerator. This generally will give you better results, but it isn't necessary. Read on for further instructions.
Step 4: Add your prepared fruit to a heavy-bottom large saucepan. Add lemon juice. Cook gently over medium heat for 10 minutes to allow the sugar to dissolve and the fruit to break down, if you didn't store it overnight. If you stored it overnight in the refrigerator, it will already be broken down with the sugar dissolved, in which case you should move on to step 5 right away.
Step 5: Raise the temperature to medium-high heat and let the mixture gently boil for 10-15 minutes until the temperature reaches 221°F on an instant-read thermometer or candy thermometer. This is the jam setting point, so don't take it off the heat until it reaches this temperature.
Step 6: Take the jam off the heat and let it cool completely before storing. When ready to store, ladle it into airtight, clean jars, and store in the refrigerator for up to 3 weeks.
Storing Strawberry Rhubarb Jam
Strawberry rhubarb jam will stay fresh for up to 3 weeks if stored in jars with tight lids kept in the refrigerator. Before storing, make sure to allow the jam to cool completely. Rather than storing in 1 large jar, I recommend using smaller jars to store in small batches so you can open one at a time to retain freshness.
Can you freeze strawberry rhubarb jam?
Yes! This is a fantastic freezer jam. Refrigerator jam can be frozen for up to 6 months. Allow it to cool completely, then transfer to freezer-proof containers such as jars, screw the lids tightly shut, and label with the date so you can keep track of when you froze it. Make sure to leave some clearance at the top of the container to account for liquid expansion (about one-fourth inch headspace).

FAQ
No, that step isn't necessary with refrigerator jam. Unlike other jam recipes, this jam does not require any canning. It won't last as long as canned recipes will, but it will also save you time and steps when making the jam.
