Raw plum jam - failure ?

This it the seventh recipe in a row evolving around plums a theme. And it the last recipe with plums from my plum "cook-out", so now you and I can relax without plums popping up everywhere on this blog :-)

However, I have really been in doubt, if I should share this specific recipe with you or not, as I consider it as a failure right here and now. After a discussion at work I decide to make raw plum jam or the more correct name is raw marinated plum. In order to make something with accepted shelf-life, I decided to use a ratio of plum and sugar in 1:1, so using the conserving effect of sugar. Anyway, I also decided to add potassium sorbat as well to control the growth of un-wanted micro-organisms in the raw jam.

But 2-3 days after making this raw jam, I noticed, that the jam was split into several phases: sugar at the bottom, juice part in the middle and plums in the top. So the appearance is not appealing at all. I have not taste the raw jam yet.

So right here and now I am questioning, if plums is a good fruit for raw marinating, if the sugar ratio should be lower or higher. If you have comments and suggestions on how to make raw marinated fruit, please leave a comment.

1. Stir chopped plums, sugar and vanilla sugar together.
2. Prepare the jam glasses by filling them with boiling water. Remove the water, before filling them with jam.
