Jam's and Jellies

I love to develop Jam's and Jellies. I Love to be in the Kitchen working on new methods, working with sugar levels, as I an mow Dietetic. I strive for finding the balance between flavor, and sweetness. I love to experiment with non-traditional fruit and herbs. Sometimes it works and sometimes I have a disaster. However, it works out it is always fun.What do you like to make Jelly or Jam out of?
