Different methods of making jam without refined sugar




Jam can be made thick with several different tricks. Have you tried chia seeds? In addition, you do not need to use refined sugar if you are cooking jam. There are tons of different low-calorie recipes that contain natural, unrefined, unprocessed sweeteners. Read on to learn how to make jam without sugar, and try our recipes! 

Berry jam is an excellent addition to a low-calorie diet when the jam does not contain sugar. Berry jam contains fiber, natural fats, and antioxidants. With a little practice and the right ingredients, you can make jam that is a 100% healthy product.

There are various basic methods of making jam without sugar. These are that:

  • Cook the berries without adding any thickener.
  • Use pectin or some other thickener.
  • Thicken the jam with chia seeds.

The cooking method

The easiest method to make jam is by boiling. This technique is perfect for making blackberry and raspberry jam. The boiling also helps to release the natural pectin from the berries. When the water evaporates, the berries take on the classic jam texture.


  • Place the selected berries on a tray and mash them lightly.
  • Then add artificial or natural sweetener and heat in a saucepan over high heat for a few minutes, until boiling.
  • Then lower the heat to medium while you continue to stir, and let it boil for another 15 minutes while using a spoon to remove any foam on the jam.
  • The jam is ready when the bubbles get bigger and the mixture has a creamy consistency.

The gelatin method

Many consider this to be the best method for making jam, especially strawberry jam. This is due, among other things, to the fact that strawberries contain a lot of water and not so much pectin. You can choose between using unflavored gelatin powder or gelatin sheets.


  • 1 glass of water
  • 1 portion gelatin powder
  • 5 dl strawberries, cut into large pieces
  • Optional sweetener, to taste
  • 1 teaspoon lemon juice


  • First, pour the water into a bowl.
  • Then sprinkle the gelatin powder over the water and mix well. (If using leaf gelatin, let this sit for 10 minutes in lukewarm water before proceeding to the next step.)
  • Heat the gelatin mixture in a saucepan over medium heat until it begins to boil.
  • Add the strawberries.
  • Then you add the sweetener of your choice along with the lemon juice.
  • Raise the heat and cook for three minutes.
  • Then lower to medium heat and cook for another 10 minutes.
  • Remove any foam from the surface.
  • Finally, the jam is ready when it has acquired a soft, creamy consistency and large bubbles form.

Use chia as a thickener

Using chia seeds as an ingredient when making berry jam is another method of thickening the jam. In other words, this is also a perfect ingredient when you want the classic jam consistency.

Red jam (strawberries, raspberries, and blackberries)


  • 5 dl berries
  • The juice from an orange
  • 1 tbsp orange peel
  • 1 tablespoon chia seeds
  • Sweetener (optional)


  • Place the berries in a saucepan. If using strawberries, split the large ones – you can use the smaller one’s whole.
  • Then pour in orange juice and bring to a boil.
  • Then lower the heat to medium and start mashing the fruit until they have a puree-like consistency.
  • Boil for 10 minutes and add a splash of water. You should now have a thick, soft, and creamy consistency on the jam.
  • Reduce heat to low and add the chia seeds. The mixture will now be gelatinous and grainy, similar to sugar.
  • Finally, add sweetener if desired.
  • Let cool and store in a jar.

Alternative sweeteners for jam

It is possible to find healthy alternatives to refined sugar, both natural and artificial. Many of these sugar substitutes have a high nutritional value and are potentially less harmful to our health.

You can make a berry jam without sugar with any of the following:

  • Agave syrup
  • Panel sugar
  • Maple syrup
  • Honey
  • Raw honey (add this to the jam after it cools so it retains its properties).
  • Coconut sugar
  • Molasses
  • Apple butter
  • Stevia
  • Raw, unrefined sugar

Sugar-free berry jam


  • 4 dl fresh strawberries
  • 4 dl fresh blackberries
  • 1 glass of grape must
  • 2 tbsp sweetener of your choice
  • The peel of a lemon, cut into strips


  • First, put the strawberries and blackberries together with the grape must in a bowl. Let it steep for a couple of hours so that the flavors meld.
  • Then you can add any sweetener of your choice. Stir the mixture and let stand for five minutes until the juices are released.
  • Then add the lemon peel that you cut into strips.
  • Place in the refrigerator for 24 hours.
  • The next day, pour the berries into a saucepan and cook over medium heat for 20 minutes until thickened.
  • Then let it cool before pouring the jam into a glass jar ( previously sterilized and with a lid ).
  • You can use sugar, but in that case remember that raw, unrefined sugar is the healthiest choice.
