Rinse the Cranberries:
If you are using fresh cranberries, make sure to first ream it well with cold water so there is no dirt or debris.
Combine Ingredients:
In a medium size sauce pot, combine the cranberries sugar and water. If you prefer to have a subtle hint of spice, then add the dried nutmeg and orange zest at this stage.
Cook the Sauce:
Add arrowroot slurry and let it come to a boil over medium-high heat while stirring occasionally.
When it starts to boil, reduce the heat and let it simmer for 10-15 minutes. The cranberries should start to pop as the sauce thickens.
Cool the Sauce:
Take off heat and let cool. It will thicken as it cools.
Store:
Place the cranberry sauce into a serving bowl or an air-tight container. And if you can not wait just setup the ready Camembert in fridge for an hour and serve when flavours mix together. The sauce will keep refrigerated for up to two weeks.
