I love plum jam and this is the recipe I use when I make it at home. I much prefer homemade jam to that bought at the shops.
This is a very good recipe. I make it with green gage plums, the jam turns out great. I do a very similar recipe, but with a couple of changes. I dont add citric acid or pectin, instead I add some unripe plums which provides the pectin and the citric acid. (having a plum tree in the garden helps!). And it is 'organic'! - 01 Aug 2011 (Review from Allrecipes UK & Ireland)
This was my first attempt at jam making and I have to say I hope someone gives me some plums next year, because this is great jam! It wasn't to difficult to make. The only alteration I made was to scale the recipe for the amount of plums I had. Thanks for a great recipe! - 10 Sep 2009 (Review from Allrecipes UK & Ireland)
Have used this recipe several times now and it hasn't failed me. The jam sets well, tastes fab and everyone says how wonderful it is. Will be making some more this year! - 08 Jul 2013 (Review from Allrecipes UK & Ireland)
