Add the diced pumpkin or squash, apples and onion along with the spices, sea salt and grated ginger to a large preserving pan.
Pour in the apple cider vinegar, give it a good stir and slowly bring to the boil.
Cover with a lid and simmer for 30 minutes.
Remove the lid and take off the heat. Stir in the sugar and cranberries.
Return the pan to a low heat and let the chutney mixture simmer for at least 1½ to 2 hours, stirring every now and then to prevent it sticking to the bottom of the pan.
The chutney is ready when the liquid has reduced and the pumpkin and cranberries look plump and glossy.
Ladle into sterilised jars.
Wipe the jars with a warm damp cloth. Label when cold with Spicy Pumpkin & Cranberry Chutney and the date.
