Berry Jam

Berry Jam


The first time I served this strawberry jam made with Perfect Sweet™ Xylitol at an afternoon tea with scones and cream, my guests ate the entire jar of jam!  More jam went on their scones than I have ever seen before.  I was thrilled that my first attempt at this sugar free and gluten free strawberry jam recipe was such a success and that they actually wanted to eat it straight from the jar.  

Sugar Free and Gluten Free

Makes 1 litre (1kg)


  • 60 ml lemon juice (approx 2 lemons)
  • 1kg blueberries or strawberries (hulled and quartered)
  • 125ml water         
  • 500g Perfect Sweet™ Xylitol 


  1. Squeeze the juice from the lemons, place any seeds in a piece of muslin and tie with cook’s string. You will need 60ml juice.  Set juice aside.
  2. Place lemon seeds (not the juice), berries and water in a large saucepan. Bring to a simmer and cook uncovered, over low heat for 15 minutes. 
  3. Add the lemon juice and xylitol and stir over low heat until xylitol is dissolved. Bring to the boil and cook uncovered, for 25 minutes, removing any surface scum with a slotted spoon, until jam reaches setting point (see below).  Remove the muslin bag of lemon seeds.
  4. Carefully pour hot jam into hot sterilised jars (see below) and seal immediately. Turn jars upside-down and stand for 2 minutes to sterilise lids, then turn upright to complete cooling.

Can be stored in the pantry but once opened it must be refrigerated.

Setting Point Test

Drop a teaspoon of jam liquid onto a freezer-chilled saucer and return saucer to freezer for a few seconds until jam is at room temperature. Push the edge of the jam with a fingertip and if the surface wrinkles, the jam is ready. If not, keep cooking and retest on a clean chilled saucer after 5 minutes.

Sterilising Jars

Wash jars and lids in hot soapy water, rinse well and place lids upside down on a wire rack to dry. Place jars on paper lined baking tray right side up. Place in cold oven and turn heat to 120˚C/100˚C fan-forced.  Heat for 30 minutes.

You can also place clean jars and lids upside-down in a dishwasher and put through a hot wash-dry cycle without detergent. Use the jars hot from the dishwasher.


The pectin from the seeds helps the jam to set.

And there you have it – a simple sugar free and gluten free strawberry jam recipe that is absolutely delicious. Your guests will love it!
