When I was in 4-H, I took a jams and jellies course. It was so much fun making the different kinds of jellies. Strawberry jam was my favorite, but the jellies were so easy to make if I recall correctly. The recipes called for frozen fruit juice concentrates. I remember making apple jelly and grape jelly for sure this way.
But you also make your own juices that are much more flavorful. I'm sure that course used that for teaching purposes. For example I make blueberry and blackberry jellies. and if, for some reason your jelly does't "jell", you have syrup for pancakes.
You can make apple jelly from the cores and peelings left after you've sliced apples for another use.
I used to make all kinds of jellies, jams and conserves when my kids were little. Elderberry is realy delicious if you add a bit of lemon juice. My grandma used to make strawberry/rhubarb jam that was awesome.
