Put all the ingredients in a large, heavy-based saucepan, holding back 500g of the gooseberries. Cook over a medium heat until the sugar has dissolved, then bring the mixture to the simmer and cook, uncovered, for 30 mins. Add the remaining gooseberries and cook for a further 10-15 mins or until thickened.

Spoon the chutney into five sterilised jars. Will keep for up to one month. Once opened, store in the fridge.
