I made apple jelly from the peelings of the apples that I made into apple butter and applesauce.
Unfortunately it doesn't seem to be jelling at all and I may have to retry again tomorrow :(
Edited to say: Just so you all know, it did not jell. I actually have never seen any jelly that I have tried to make come out looking just like it went in the jars. So I tried again this morning with more pectin. They aren't completely cool yet but so far they are only slightly thicker than before. I have to wonder why this is and if it is something that the apples are sprayed with prior to our buying them in the store that causes this.
