How to make your Strawberry Rhubarb Jam

Wash and dice your rhubarb.

Combine rhubarb, strawberries, pectin and lemon juice in a large pot. Bring to a boil, stirring constantly. It may seem dry to you, that is ok. The juice from the strawberries will start to run and it will get juicy as it heats. I like to use a potato masher to help mash up the fruit.

Add sugar and bring back to a boil again stirring constantly. Boil hard for 1 minute.

See how I have two pots going at the same time? I think this picture below is actually when I was making just strawberry jam. I didn’t get a picture of my two pots going with the strawberry and rhubarb. But the procedure is the same. Be sure and switch back and forth stirring each pot as it heats.

The jam may foam up on you so be sure your pot is large enough. As it cooks the foam will die down. At the end of your cooking time skim any foam left if necessary.

This is quite often needed when you are doing any type of strawberry jam. Another option is to add about 1/4 tsp butter to the pan. This does help stop foaming.

Remember since you’ve got pectin in this recipe you only need to boil hard for 1 minute. The pectin takes care of making your jam gel up nicely.

When one minute boil is over, fill hot jars with hot jam leaving 1/4 inch headspace. Wipe your rims as any sticky residue may cause your seal to fail. Then add the lids and screw bands and put the jars in your waterbath canner.

Process according to water bath canning instructions.

Process

The processing time is for 1/2 pints or pints.

Don’t double up jam recipes.

One tip I have when canning any jam recipe is not to try and do double batches. It is VERY tempting to double jam recipes and make more. However, it is difficult to make double batches of jam. They just don’t set up very well. Some people do double up on batches, and you can certainly try because it is not a safety issue. But I have a better idea. If you want to make more at a time (I don’t blame you) simply have two batches going at the same time in different pots.

Jam Separation in the jars. Floating Fruit!

Sometimes strawberry jams (including with rhubarb) will separate in your jars. YOu’ll end up with a layer of fruit floating on top of a clear layer. This is not dangerous in any way but not appealing. One suggestion is to allow your jam to rest for about 5 minutes after you boil it before you put it in the jars. Then give it a good stir and fill the jars. This will allow the jam to cool ever so slightly and mix the fruit back up. If it happens to you anyway just stir up the jar when you open it to use it.

So much sugar! Find a low sugar option here.

This jam is a traditional jam and has lots of sugar. My family likes full sugar jam! We just use it as a condiment so it is not a problem. But… I have been working on getting lower sugars into my guys. This is how I’ve been doing this with mostly success!

FAQs

Is it better to use fresh or frozen strawberries for jam? ›

The best jam is always from fresh fruit that is almost, but not quite ripe. The jam I make from frozen fruit is almost as good as from fresh, and certainly tastes better than jam left around for a year.

What happens if you cook strawberry jam too long? ›

Without pectin, strawberry jam needs to be cooked much longer to start jelling, if it actually ever does. That means you'll not only overcook the fruit but you'll loose that beautiful, bright berry color.

Why is rhubarb always paired with strawberry? ›

Rhubarb, when mixed with strawberries, gives you that sourness to balance the sweetness and the complexity.

Does rhubarb have a lot of pectin? ›

Because rhubarb doesn't have much pectin, and often add apple juice which helps the jam to set nicely. In a large pot, mix the rhubarb, berries, and the water or apple juice.

Do frozen strawberries taste as good as fresh? ›

Though texture is important, the biggest reason you should use frozen instead of fresh strawberries comes down to flavor. You might be surprised to learn that frozen strawberries actually have a better flavor profile when compared to fresh.

How long does homemade strawberry jam last? ›

Homemade strawberry jam can be stored in the refrigerator for up to 3 months once opened. If you want to extend the shelf life of your homemade strawberry jam, don't forget to process it in a hot water bath. This makes the jam last for more than a year when stored in a cool, dry place.

Does lemon juice thicken jam? ›

Lemon is crucial to balancing those sweet flavors, but it also helps the pectin to firm up the jam. It can be added at the start of the cooking process or towards the end, but what must be taken into account is that adding liquids to the jam mixture will inevitably require the jam to cook for longer.

Can you reboil jam if it doesn't set? ›

If the jam is still liquid then we don't particularly recommend reboiling. It can be tried but there is a risk that the jam becomes over boiled, which also means that it will not set. The jam can also burn much more easily when reboiled. The thin jam can be repurposed as a sweet chilli sauce.

Can you overcook jam without pectin? ›

You are in good company. Most of us who make pectin-free jams and other spreads overcook a batch or two every year. I personally have no problems making peach jam, apricot jam or plum anything, but have great difficulties with berry or cherry jams.

Why can't you eat rhubarb? ›

The bottom line. Rhubarb leaves contain high amounts of oxalic acid, which can cause health problems when eaten in higher amounts. Symptoms of toxicity include mild gastrointestinal symptoms, as well as more serious problems, such as kidney stones and kidney failure.

What spices go well with rhubarb? ›

While cinnamon may be a more common spice to pair with rhubarb, citrusy, herbal cardamon lends a warm, citrusy note to a dish. A big pinch of ground cardamom can be added to any cake, pie, or compote, or you can simply add a little to the whipped cream you'll be topping your rhubarb dessert with.

What fruit compliments rhubarb? ›

Ways to enjoy rhubarb

Stewed rhubarb pairs well with flavours such as ginger, vanilla, cinnamon and caramel or with fruits such as apples, oranges, lemons, plums, raspberries, strawberries and blackberries. Mellow flavours such as vanilla ice cream or custard complement the tartness exceptionally well.

Why is rhubarb a laxative? ›

Sennoside A and other dianthrone derivatives are reported to be the active ingredients causing rhubarb's laxative effect (6). They are metabolized by β-glucosidase of enterobacterial origin and are converted into rhein anthrone, which produces the purgative activity.

Why did my rhubarb jam turn brown? ›

This is a process of color loss and does not mean the jam or jelly is going bad. The browning starts at the top of the jar and slowly works its way down. If your jars were properly sealed and the seal is still intact, the jam or jelly, although not as pretty as it once was, is safe to eat.

Who should avoid pectin? ›

Some people have reported mild stomach cramps and diarrhea while taking MCP. People who are allergic to citrus fruits should avoid MCP. Also, MCP may interfere with certain cancer treatments and should not be taken without supervision. Pectin can reduce the body's ability to absorb beta-carotene, an important nutrient.

Can I use frozen strawberries to can jam? ›

Making homemade strawberry jam is quite simple and you can even use frozen strawberries. This means that you can make it all year long, even when strawberries aren't in season.

Do you need to defrost strawberries before making jam? ›

Frozen fruits can be used in the same way as you use fresh fruits, but you need to thaw them first and then proceed with the recipe. One thing to note, ensure that you don't leave the frozen fruit out to thaw several hours.

Can I freeze strawberries before making jam? ›

Yes, jam can be made from frozen berries, but we much, much prefer to use fresh berries as they aren't as watery and are better in flavor.

What are the best strawberries for jam? ›

Recommended Varieties

Allstar, Cabot, Chandler, Earliglow, and Jewel and are usually excellent-quality berries for freezing. Most other varieties are suitable, especially for making jams and eating fresh. Locally grown strawberries are best for making jams and freezing.
