My grandparents have been telling me that they have some plums for me to make into jam since last week. As a bit of a jam amateur, I hadn’t even heard of plum jam, but apparently it’s pretty awesome. My step grandad was golfing when he found thousands of unpicked plums lying under their tree on the course. Being the resourceful person he is, he picked almost 7 lbs worth – to the point that his golf trolley couldn’t stand up properly anymore under the weight.
It was a bit of a family event – my dad and I sat together and cup all the piths out of the plums. Then it really is the simplest method. I just added a tiny bit of water – not much at all and some sugar – put it on the stove and left it to cook at a medium heat. My grandma, who is a jam expert, explained that as plums have lots of pectin naturally, you don’t need to add any more for them to set nicely.
