Trying to turn jam into leather

I decided to go through my jam cupboards yesterday to see what I had left.  Based on yesterday’s stock, I decided that next year there were some types of jams/fruit spreads that I would no longer make.  My eating habits have changed.  The question was, what to do with all of the jam that I knew should be used up shortly.  I really doubt that people would want 18 jars of one kind of jam.

The main problem with turning jam into leather is the sugar content.  It is just way too high.  My solution is:

  • dump all of the jam into a large pot
  • added water to dissolve
  • add fresh/canned/dried low sugar fruit to reduce the sugar content

Now the question is what fruits to use.  I found a chart listing the sugar content.  This should give me an idea on where to start.

(grams sugar per 100 grams; Tot. met. = Total metabolic)
