I love making small batches of jams and jellies. We’re not huge jam eaters in our house, plus I like the ability to try lots of different flavors. As much as I love strawberry rhubarb jam, the addition of balsamic vinegar really takes it up a notch and makes it something special.

With both strawberries and rhubarb in season, this is a great way to preserve that over abundance of harvests. These make great gifts too!

After cleaning and hulling the strawberries, crush them up. I used a potato masher in a large bowl. This is a great way to mash up the diced rhubarb as well.

Balsamic vinegar comes in so many ways. There are many years old bottles that tend to be very expensive and cheaper mass made versions as well. Save your special well-aged balsamic for drizzling on bread or even ice cream (seriously!) and use a less expensive version for this jam. While it certainly adds to the flavor depth of the jam, it is not so pronounced that you need to spend extra money on it.

So many jams and jellies can be full of sugar, this recipe calls for a relatively low amount of sugar. Because of this however, a specific low or no sugar pectin must be used.

Canning Jam Safety

Remember, to process jam safely for yourself and loved ones. All jam needs to be processed in a water bath canner. Do not simply pour into jars and seal.

If you prefer not to can, this jam can be frozen or refrigerated immediately for storage.

Frozen jam should be used up within 6 months. If refrigerated, use up within 1 month – longer may be okay, but watch for mold.

There are so many wonderful ways to preserve and use rhubarb. Be sure to try our Rhubarb Custard Pie!

Wednesday 5th of July 2023 you think it would be ok to skip the rhubarb and do all strawberry? I already do a strawberry rhubarb jam. I found a chocolate espresso basalmic that I want to use for the jam. All the other recipes I found were regular pectin and a ton of sugar and I don't like to use that much sugar.

the flavor is perfect, but mine didn't set well (It's runny) - what might have went wrong?

It could be a couple of things- not enough pectin, did reach a hard enough boil, or too large of a batch. The good news is that would still be delicious on crepes, pancakes, waffles, ice cream, french toast, and I bet even cake!
