Low Sugar Blueberry Jam (No Pectin)

Please follow and like us:

This homemade jam is easy to make, low in sugar and doesn’t use pectin!

You only need four ingredients to make this easy blueberry jam recipe – fresh blueberries, lemon juice, sugar and salt.

Since this recipe uses less sugar it is lower in Weight Watchers points.

I was able to get 18 servings (1 tablespoon per serving) of jam which came out to 1 point for Weight Watchers blue plan, green plan and purple plan.

Blueberry season is coming to an end so what better way to use them up than making homemade jam?

Since blueberries are naturally high in pectin I did not need to buy a box of pectin.

Pectin is a naturally occurring starch. When heated it helps to thicken the jam. If the fruit doesn’t have enough you can buy a box of pectin from your local grocery store.

I prefer using fresh fruit for homemade jam but you can also use frozen. For best results I would let the fruit thaw in the refrigerator over night. This will help get rid of any excess water.

Why make homemade jam?

It’s easy and delicious!

This recipe makes a small batch so there’s no need for canning.

It’s a low sugar jam making it low in points. There’s about half as much sugar as commercial jams but you won’t even miss it!

How do you make homemade jam?

Rinse your blueberries with water but do not soak them. Add them to a large saucepan with the sugar, lemon juice and salt.

Once the blueberries start to break down you want to bring it to a full rolling boil. Make sure you occasionally stir the blueberries so they don’t stick to the pan.

Continue to let the blueberries simmer over medium low heat. You can use a potato masher to break down the blueberries.

If you like your jam on the chunkier side you can use a whisk to break them down part way.

Let the jam simmer for 20 minutes. It will reduce slightly and start to thicken. Remove from heat and let the jam come to room temperature.

Once cooled I put my jam in a jar and kept it in the fridge. It will stay good in the fridge for up to a month.

If you like your jam on the sweeter side you can add more sugar, just be sure to recalculate the points.
