Sugar Free Strawberry Jam

There was a crispness in the air this morning at the my place in Pozieres QLD and it got me thinking about home preserving; in particular, jam making. Jam reminds me of my childhood, making jam with mom. But unlike then, I now choose to make jam without all of that added sugar.
Here is the recipe for my sugar free strawberry jam.    


  • 1 Kg Strawberries, hulled, halved or quartered, depending on their size
  • 300 to 400 grams xylitol
  • 2 teaspoons of Low Methylester Pectin
  • 2 teaspoons calcium water (see the pectin instructions or this video)
  • 2 tablespoons of lemon juice


1. Prepare your 250ml jars and lids by sterilizing them in boiling water for ten minutes. The sterilisation step can be skipped and you can use washed, rinsed, hot jars if you are processing for 10 minutes or more in the boiling water bath at the end of the recipe.

2. Wash and hull your strawberries. Place them into your preserving pan and give them a mash with a potato masher to release some of the juice and natural pectin.

3. In the meantime, time mix you Low Methylester Pectin with 100 grams of your xylitol or sugar.

4. Slowly add your xylitol-pectin or sugar-pectin mixture, stirring constantly to ensure that it is evenly distributed throughout your fruit mixture.

5. Add your lemon juice, calcium water and your remaining xylitol or sugar and mix in well.

6. Using a high heat and stirring occasionally, bring your jam mixture to a full rolling boil. Boil for one minute. Remove from the heat. 

7. Using a ladle and jar funnel place your jam into your hot, 250 ml jars, leaving a one and a half centimetre headspace. Clean the rims of the jar to ensure you get a good clean seal and cap with your new lids.

8. Process your filled jars in a boiling water bath for five minutes.

9. Alternatively, if you did not pre sterilize your jars and lids, process in a boiling water bath for 10 minutes.  

Special note: Low Methylester Pectin is a special type of pectin that does not require sugar to set. Instead, it requires calcium. This calcium comes with the Pomona’s pectin, along with full and easy instructions on how to mix your calcium water required in this recipe.

Enjoy. Valerie
