Ingredients

  • 2 cups / 300g blueberries, frozen or fresh
  • 2 tbsp water
  • juice of 1/2 lemon
  • 2 pinches xanthan gum
  • optional: 1 tsp vanilla extract

Instructions

  • Put the blueberries, water and lemon juice (and vanilla, if using) in a non stick pan, cover and bring to a boil.
  • Remove the lid and cook on a medium heat for ca 15 minutes, stirring regularly. The mixture will reduce by 1/3 and thicken. Smash the berries with a spoon while they cook.
  • You can blend the mixture if you wish to have a smooth consistency. I like it the way it is, with a few bits and pieces in it.
  • At the end, take a couple of pinches xanthan gum and sprinkle it evenly into the pot, stirring well afterwards. Xanthan gum is a brilliant thickening agent and is also used in gluten free baking, so it does come in handy. You only need a tiny amount - it's quite remarkable.
  • Pour the mixture into a clean jar and store in the fridge. This recipe fills a small (200ml) jar.

Notes

A this mixture makes 200g jam, I calculated 1 portion=14g=1tbsp.
Recipe Tip - How sweet your jam is will depend on the natural sweetness of your blueberries. If you find the jam is not sweet enough, feel free to add a teaspoon or two of powdered erythritol or 4-8 drops of stevia glycerite
