Ingredients

  • 2 pounds / 900g oranges (about 3 large organic oranges)
  • juice of 1 lemon
  • 2 cups / 480ml water
  • 1.5 cup / 240g powdered sweetener ***see notes

Instructions

  • Wash and scrub the oranges to remove the wax on the skins and cut off the tops and bottoms. Quarter, remove any seeds and slice as thinly as possible. Put into a saucepan together with the juice of 1 lemon and 2 cups of water. Bring to the boil, then simmer for 2 hours with the lid closed.
  • Take off the lid and increase the temperature to medium. Add the sweetener and let the marmalade bubble away and reduce, stirring regularly (especially towards the end). Adjust sweetener, adding more if required.
  • Fill the marmalade into glass jars and store in the fridge.

Notes

2.1g net carbs per 1 tablespoon of marmalade. Makes about 700 grams of marmalade.
Adjust the sweetener to taste - and use 2 cups for a sweeter marmalade.  
***Allulose is the only low carb sweetener that stays completely smooth when cooled and does not re-crystallise. You do get a little crystallisation with erythritol. However, if you use powdered erythritol this is minimal and I does not bother me. 
Choose organic oranges with a thin peel. Juicing oranges are normally a good choice. Slice as thinly as possible. 
This marmalade is slightly bitter, which I love. To reduce the bitterness, simply use a little less peel. Just remove and discard the peel from one of the oranges, for example, and use only the fruit. 
You can replace the oranges with tangerines or even lemons.  
Store in the fridge for up to 3 weeks or freeze for up to 6 months. Not suitable for canning.
