When I posted the plum jam recipe, someone asked me about a sugar-free plum jam recipe. To be honest, I never tasted it and I thought it was something dietetic and sour, I wasn't too tempted to try it. But, I had received as a gift a small jar of sugar-free plum jam, and I was very impressed by the taste, texture, aroma - wonderful!
Since then we only buy sugar-free plum jam from the supermarket, from the organic one - on a slice of wholemeal bread it is a perfect and very delicious dessert.
Now I gathered a large bucket of plums from the garden and the only thought was this delicious jam, I knew I had to be patient and boil it a lot, so it was, I even boiled it for 2 days each a little - but it was worth it. I came out very good, a little sour, fragrant and perfect texture / color.
So, be patient to boil it, even more than 4--5 hours, in 2 days if you do not have time to sit next to it for a day. If you boil it less, a very sour plum jam will come out and you will say that it didn't come out and you don't know why.
