Place the prepared gooseberries in a large jam pan and add 500 ml water. Put a small plate or saucer in the freezer, and have four sterilised jam jars with lids ready.
Bring the pan it to the boil, then reduce the heat and simmer for ten to fifteen minutes until the gooseberries are soft. If yours are a little unripe like ours were, or if they are quite large, this might take longer. Make sure they are all soft before carrying on.
Now add the sugar and cook on a low heat for ten to fifteen minutes until all that sugar has dissolved and you can't see any grains of sugar anymore.
Next, you will need to bring the pan to the boil again and let it boil for about ten minutes. If you have white foam forming on top, skim it off with a slotted spoon.
After ten minutes, the jam should have changed from a light green colour to a pinky brown colour, as the fruit in the jam cooks.
Now get the plate or saucer out of the freezer and drop a small spoonful of jam onto it. Wait a few moments then test it with your finger. If it wrinkles up when you run your finger through the jam it has reached setting point.
Pour the jam into your prepared sterilised jam jars and seal with the lids.
Leave to cool. Enjoy on toast, in cakes, desserts, with meringues or however you fancy!
