I'm not very successful making apple jelly. I had a jar that was sweet
juice. I decided to boil it some more in an attempt to get it to set.
I boiled and boiled. The jelly wouldn't sheet off the spoon. The
spoonful popped in the freezer continued to run. Finally, the jelly on
the plate set. I poured the jelly into a jar. As it cooled, the jelly
turned solid. It is now a really sweet fruit leather

I've got two more jars to boil down.

What's the trick? This is the second time I made candy -- at least
this time it isn't scorched.
