With a freezer full of plums picked from our tree last summer, I decided it was time to do something with them. Plus we needed the freezer space for essentials. Jam and a crumble (with lashings of custard, of course) are two of the best uses for plums. On this occasion , however I decided to make jam. After searching successfully for jam sugar in the supermarket, I managed to fill 4 jam jars and 1 miniature jar. This jam is particularity good mixed in with a bowl of porridge for breakfast and sprinkled with cinnamon.
