I used a few cups of concord grapes, and a few wild apples. The wild apples are small and green and have high amounts of pectin. I used 3 apples.
I threw everything in a pot, and added a little apple cider so the pot wasn't dry. Simmer till cooked, and run through a seive. All directions for jelly said to chill the juice oevr night, and restrain to remove the grape crystals. I did that, but it didn't really seem that different to me. Put it back into a pot, and added 3/4 cup maple syrup. I cooked it and allowed the steam to come off a bit to thivcken, and then poured in to jars. It has jelled, and is delicious!
No sugar or pectin (well only natural from the apples and grapes)!
I am going to make lots more now that it works!
