Have you ever tried making jam? I used to help my mom and grandmother make apricot and peach jam when I was a kid but I had never tackled it on my own, and they never made strawberry jam.
So with some guidance from my mother-in-law, who has made lots of strawberry jam, I experimented until I got it just right without having to add pectin. I wanted to avoid using pectin, she said she never used it in her jams either. So I felt that I could get a good consistency without it.
In the Carolinas, it’s very difficult to find local rhubarb. The reason is that rhubarb is a perennial that grows mostly in the North because temperatures need to be below 40º in the winter and around 75º in the summer.
Around here it rarely gets below 75º in the summer. If you’re in an area that grows rhubarb, you might find these tips helpful if you want to grow some in your backyard.
Apparently, you can still grow rhubarb in the South if you treat it as an annual. Plant it in the fall and it should come up in the Spring. I have to rely on Whole Foods, where I can normally find some great looking rhubarb in the Spring.
Does Strawberry and Rhubarb Jam need pectin?
Pectin occurs naturally in fruit and it’s what makes the fruit jell. Some fruits like apples and lemons are high in pectin which is why you want to add lemon juice to strawberry jam. Both strawberries and rhubarb are not high in pectin. Commercially made pectin like Sure Jell can be used but lemon juice will give you a more vibrant flavor.
Strawberry Rhubarb Jam Recipe ingredients
- Strawberries – while you want sweet ripe strawberries for the best flavor, try to use about a quarter of strawberries that are less ripe. The riper the fruit, the less the pectin.
- Rhubarb – Try to find crisp stalks, the color doesn’t make any difference in whether it’s ripe or not.
- Sugar – I start with two cups and add more if the strawberries are not sweet.
- Lemon juice – use fresh if you have it. But if you only have the bottle kind, it’ll still work fine. Just add about a tablespoon.
How to make Strawberry Rhubarb Jam
How to prepare rhubarb for jam
Rhubarb comes in large stalks that looks similar to celery. Just wash it and cut off the exposed ends. Then slice it into small pieces.
Cut up the berries and rhubarb, add sugar and let it sit for an hour. I used an equal amount of strawberry to rhubarb ratio and found that 2 cups of sugar for 2 lbs of fruit resulted in the perfect sweetness for me. However, if you like sweeter jam, most recipes call for an equal weight of fruit to sugar.
Place the fruit mixture in a saucepan, add lemon juice and cook it on high until it starts to thicken. You might think it will never thicken but give it about 10 minutes or so and it will start to coat a spoon.
PRO TIP: You will a hear the jam sizzle when you drag a wooden spoon through it. When you hear the sizzle you’ll know it’s done. It’s because the jam has reached about 220 degrees, the perfect “set time” for jam. But if you take it off early, it’s no big deal, it will thicken as it cools and it still tastes great regardless of how runny it is. Mine takes about 10-15 minutes depending on how juicy the fruit is.
Rhubarb Strawberry Jam variations
- Try adding a ½ tsp of vanilla extract to the mix.
- Add ¼ tsp of black pepper to the mix for a deliciously fun kick to the sweetness.
How to can Strawberry and Rhubarb Jam
When you start cooking your fruit, turn on the heat for your canning pot, it takes forever to bring that much water to a boil.
Once it comes to a boil add the jars to sterilize them for about 10 minutes. Also sterilize the lids by pouring some of the the boiling water into a small sauce pan, let them dry on a clean towel while the jam is cooking.
Ladle the jam into the jars and wipe off any jam that got on the rim with a wet paper towel. Add the lid and then the rim, tighten slightly and place the jars back in the water bath letting them boil for 10 minutes.
Remove and let them cool. Within just a few minutes you’ll hear the lids pop. Once they are cooled, make sure the lids are sealed by pushing on them. If they indent, then it didn’t seal and you should put that jar in the fridge to eat now. All mine have sealed so far using this techinque.
If you need more details go to the National Center for Home Food Preservation.
Of course you don’t have to can it at all, you can freeze it if you have room in your freezer and it will last a year until next years crop is ready to pick.
What to do with Strawberry Rhubarb Jam
I’ve made three batches so far and all taste a bit different even though I used the exact same proportions. The reason is that every batch of strawberries will add a different flavor, some are just going to be sweeter naturally than others.
If you’ve never tried strawberry rhubarb jam you don’t know what you’ve been missing. This is amazing on toast, for peanut butter and jelly sandwiches, add to some yogurt, on biscuits, over ice-cream. You can use it as a filling in cake, or filling in a thumbprint cookie or as a pancake topping. I think you get the picture.

Rhubarb is not high in pectin which is why it helps to add lemon juice which is very high in pectin.
If you have very juicy strawberries your jam may take longer to cook before it thickens. When you run a wooden spoon through the bottom of the pot, the jam should not fill up the space right away. If it does let it cook a little longer.
