🍓 How to Make Strawberry Rhubarb Jam
Step 1: Wash and slice enough rhubarb to equal five cups. Prepare fresh strawberries by removing the leaves and slicing them in quarters.
Step 2: Place rhubarb in an eight-quart Dutch oven and sprinkle with some of the sugar. Add prepared strawberries and cover with the remaining sugar.
Step 3: Add lemon zest and juice of one lemon. Quarter the juiced lemon and add to the pot, along with the cinnamon, and cardamom. Cover with the remaining sugar.
Pro Tip: Citrus fruit are naturally high in pectin and will make up for the lack of pectin in the strawberries and rhubarb.
Step 4: Place the lemon seeds inside of a tea ball or soup bag and add to the pot. Lemon seeds are also loaded with pectin. Place the pot over low heat, uncovered, allowing the sugar to melt slowly.
Step 5: Once the sugar begins to liquefy, gently stir so that the fruit does not get scorched.
Step 6: When the mixture begins to boil, adjust the heat to low-medium and allow the preserves to simmer for approximately 20 minutes. Skim the foam that forms on the surface with a spoon.
Step 7: A quick way to test the jam's consistency is to take a few tablespoons of the jam and place it in the refrigerator for five to ten minutes. If the jam does not jell, it needs to simmer further.
Step 8: Meanwhile, place the jars into water bath canner. Boil for approximately ten minutes to sterilize.
Step 9: When you're satisfied with the texture of the jam, remove the jars from the hot water and add the lids and rings. Remove the lemon rinds and carefully pour the hot jam into the sterilized jars, leaving a ¼ inch headspace.
Step 10: Wipe off the rims and sides of the jars with a damp washcloth or paper towel. Screw the lids on hand tight and place the jars upright into the hot water. Process for an additional ten minutes.
Pro Tip: When processing food at higher altitudes (1000+ feet above sea level), more processing time is required. Add an additional 5 minutes for every 1000 feet above sea level.
Step 11: Remove jars and place on a rack or a dish towel. Once the jars seal, tighten the lids and store in the pantry for up to a year.
🤷🏻♀️ Recipe FAQs
Rhubarb is low in pectin, which is why you'll often see rhubarb jam recipes that include liquid or powdered pectin.
There are various ways to thicken rhubarb strawberry jam. One way is to use citrus, for example, a lemon. Not only is lemon juice high in pectin, but so are the pith and seeds. After zesting and juicing the lemon, add the entire lemon in with the jam and fish it out just before canning the jam.
Readers always want to know if they can reduce the amount of sugar in jam recipes. Although reducing the sugar sometimes works, most of the time it keeps the jam from jelling and results in a jam that's too watery.
I would suggest reducing the amount of sugar by no more than ½ of a cup at a time. If the jam is too watery, you can still save it by stirring some liquid pectin into it and boiling the jam for a few additional minutes.
👩🏼🍳 Pro Tips
- I've noticed a lot of rhubarb strawberry jam recipes use an equal amount of strawberries to rhubarb. If you use an equal amount, the strawberry flavor tends to overpower the rhubarb. You can either use equal amounts of the two or stick to the measurements above.
- Resist the temptation to cook this jam longer, thinking it's not thickening. Instead, test a small amount at the 20-minute mark to see if it needs further cooking.
- If you decide to reduce the amount of sugar in this rhubarb strawberry jam recipe, you may want to add liquid pectin so that it will jell properly.
- If you prefer a smoother texture, allow the jam to cool, then blend using an immersion blender. Once you have the desired texture, heat jam once more before canning and processing.
- If you want the flavor of this strawberry rhubarb jam to really stand out, add a pinch of salt, and leave out the cinnamon and cardamom.

This recipe is so easy to follow and yields a lot! I got 6 half pints and 3 1/4 pints. I made it last year with cinnamon. This year I tried it with the salt. Maybe it's just my imagination or the fruit I used was even better than last years but it was so flavorful! I would have never thought I would like Rhubarb but this is actually one of my favorite jams! Thanks Hilda for the Rhubarb and the great recipes!
