Step 1

Put all of the ingredients in a small-medium saucepan and put on a medium heat. Stir as it heats to dissolve the sugar and use a potato masher to break up the fruit a bit as it softens. As it cooks, prepare your jar/jars - either warm in a low over a few minutes or submerge in boiling water to sterilize. Take care using tongs/gloves to handle as you remove.

Step 2

Bring the jam to a simmer, reduce the heat a little and simmer for approximately 15 minutes. It should become darker in color and a bit thicker. It won't likely fully set (see notes).

Step 3

Remove the pan from the heat, allow to cool a minute or two then skim off any foam. Transfer to your prepared clean jar(s) and put lid on while still hot. Leave to cool.
