Place all the ingredients into a heavy based saucepan and bring to a simmer.
Once the mixture comes to a light simmer leave it to cook for 2-3 hours depending on how thick you like it. As it simmers away the plums will begin to break down, you will know when the chutney is ready when the onions are translucent, and the mixture sticks well to the back of a spoon.
Once the chutney is nice and thick remove it from the stove, allow it to cool slightly before placing into steralised jars. If you don’t have steralised jars place the chutney into containers and keep it in the fridge.
This chutney is the perfect accompaniment for Christmas ham, or a perfect
cheeseboard condiment. Enjoy.
