I have just found this and I've not tried it. I want to next holiday season though so I'm posting it to keep it safe. I'm thinking that the fine grating disc of the food processor *might* do the trick as I don't have a food grinder. Tprep time is a guess. The 20 mins cook time is for canning if you choose not to freeze it. While this says "No Added Sugar" it contains tons of natural sugar in the fruit.
