I find this Cranberry Clementine Sauce keeps for an inordinately long time in the fridge since the sugar syrup preserves the sauce very well. You can easily make this sauce weeks in advance, although there’s no guarantee there’ll be any left for Christmas Day if you do that.
I have also had great success in canning this Cranberry Clementine Sauce via the water bath method to ensure extra longevity. After all, I still want to be eating my cranberry sauce well into June next year.
This recipe was adapted from a cookery class I attended many years ago at Divertimenti Cookery School in London. I have long since lost any details regarding the original writer of this recipe or which cookery class it was exactly I attended. It’s a pretty safe bet it was some sort of a Christmas cookery class though.
