Low Sugar Three Berry Jam Canning Recipe With Pectin

We have several berry bushes on the farm, but they never produce at the same time.  Some nights we get a handful of berries; a week later I'll get a few cups.  

We eat them plain, and I also freeze them in bags to save for later.  When I get enough berries, that's when I make this easy mixed berry jam recipe.

I used Sure Jell for low or no sugar to make a low sugar triple berry jam recipe.  This is the pink box of pectin.  We'll talk about how it's different than the yellow box plus tips for making a delicious jam.

How Do You Make 3 Berry Jam?

This easy mixed berry jam recipe is made with strawberries, raspberries, and blackberries.

Other recipes may be different, but this is what I use because we grow those berries on the farm.  This is also the recipe in the box of Sure Jell.  

If you use different berries, the amount of fruit needed for a batch can be different.  This is because fruits have natural pectin, but the amount varies by type of fruit.

For this reason, it's important to follow the directions for the type of fruit carefully for a good set.

You can learn more about pectin and getting a good gel in my how to fix runny jam or runny jelly post.

Can You Use Frozen Berries to Make Jam?

Yes, you can absolutely use frozen berries to make a triple berry jam recipe with pectin.  I have bags of berries in my freezer, and I add more when we pick them.

You don't have to thaw the berries to make this mixed berry jam canning recipe.  However, you might want to let them thaw slightly just to measure.  

Alternately, you can measure the berries and freeze them to make a low sugar mixed berry jam recipe when you have more time.

Does Pectin Require Sugar?

Berries have a high water content in them.  Sugar helps draw out the water, which then preserves the jam by allowing chemical bonds to form between the water and sugar to prevent microbes from growing.

Sugar is also needed for a gel.  Pectin bonds with both water and pectin.  If there's a lot of water, the pectin binds with the water and doesn't gel.

Adding sugar pulls the water from the fruit so the pectin can form a gel.

Can I Use Regular Pectin for Low Sugar Jam?

The three berry jam will be edible if you use regular pectin, but you need to use Sure Jell for low sugar or no sugar recipes in order to get a good gel to make a low sugar triple berry jam recipe.

Can I Make Berry Jam Without Pectin?

For an easy mixed berry jam recipe, you can make a small batch of chia seed jam.  Learn how to make chia seed jam with any fruit.

You can also make small batch mixed berry jam recipe by using this Instant Pot strawberry jam recipe and substituting raspberries and blackberries for part of the strawberries.  

Note that this may not thicken as well because raspberries and blackberries are lower in natural pectin than strawberries.  However, it will still taste good!

Can I Use Stevia Instead of Sugar in Jam?

You can not use stevia for this triple berry jam canning recipe.  However, you can follow the directions inside the Sure Jell for no sugar box to make a no sugar needed jam and use stevia.  

Why Do You Add Butter When Making Jam?

When you boil this triple berry jam recipe, foam forms on the surface of the jam.  This is normal and happens with most jam recipes. 

This is due to the proteins opening and forming strands that get tangled as you stir.

Adding a little bit of butter (fat) breaks the surface tension and prevents foaming.  

You can also simply skim off the foam with a spoon.

Tips for Making Mixed Berry Jam Canning Recipe

Here are some tips to help you make the best triple berry jam recipe:

• It's very important to use the right amount of each ingredient.  The ratio of the mixed berries, sugar, and pectin is what creates the gel.
• Make sure that the jam comes to a full boil that can't be stirred down.  Then it should be at a hard boil for exactly one minute after you stir in the sugar.
• Do not double this triple berry jam recipe with pectin.  It can prevent the jam from gelling.  You can, however, make one batch and put it in jars in the water bath and then make another batch and can both at the same time.
• I use the rack from my pressure canner to give me more space in my water bath canner so I can process two batches at once.
• You can use fresh or frozen berries to make three berry jam.
• Make sure you wash and sanitize your jars before using.
• Some people do not water bath jelly and just turn their jars over.  This isn't considered safe, and I always recommend that you water bath your jars.  Learn about 11 canning mistakes that can kill you.
• Let your 3 berry jam sit for 24 hours before testing the seal.  Learn more about canning jars not sealing and how to reprocess canning jars.
• Learn how to clean and sterilize glass jars for canning.

How to Make Low Sugar Triple Berry Jam Recipe

Step #1

Wash and dry berries.  Cut the tops off of the strawberries.  Use a dry measuring cup to measure the crushed berries.  Place in a large saucepan.

Step #2

In a separate bowl, place the sugar.  Then take 1/4 cup of the measured sugar and combine it with the powder from the box of Sure Jell pectin.  Stir well.  

Step #3

Add the pectin and sugar mixture to the berries in the pan.  Turn the heat on medium high and stir constantly until the berries reach a full boil that can't be stirred down.  You can raise the heat if needed.

Step #4

Once the berries are boiling, stir in the remaining sugar.  Bring it back to a full boil while stirring.  Keep stirring and boil for 1 minute.  Remove from heat and skim off any foam.

Step #5

Ladle the three berry jam into prepared jelly jars.  Leave 1/4 inch head space.  Wipe the jar rims and cover with a new canning lid and place a ring on it.

Step #6

Place the jars in hot water in the canner.  Add more hot water if needed to bring the water to cover the jars by 1 to 2 inches.  Cover and bring the water bath canner to a full boil for 10 minutes.  Then remove the lid and turn off the heat.  After 5 minutes, use a jar grabber to carefully remove the jars and place on a heat proof surface.  

Let the triple berry jam canning recipe sit for 24 hours without touching them.  

You can store this easy mixed berry jam recipe for up to a year.  Low sugar jam recipes have a slightly shorter shelf life due to less sugar.

I hope you enjoy this small batch mixed berry jam recipe!
