Put sugar and orange juice in a pot and stir until the sugar is dissolved.
Add the cranberries and boil for aprox. 10 min until the berries begin to burst.Take of the pot and then the sauce is ready to serve.
Tip
If you want a thicker sauce then boil them a bit longer but be aware that the sauce also gets thicker as it cools.
If you want a sauce which is a bit out of the ordinary try adding a bit of cinnamon, ginger, zest or port. This twist the taste a bit and gives it a uniqueness.
