A friend of my mom's used to make syrup from apple cores and sugar ( and red food coloring), but none of her kids knew how she did it when I called to ask. But, I found something that sounds similar in this month's edition of Southern Living. It's called brown sugar apple simple syrup.   Said to let cool, put in refrigerator, but I don't see why you couldn't can this do you? When I try this, I will add a touch of cinnamon. Would be good on oatmeal or in hot tea, something like that. Or poke holes over a cake and let it soak in. If it were thicker, it would be great for pancakes or stuffed french toast.

2 cups apple peels

2 cups packed brown sugar

2 cups water

Put everything in a saucepot, simmer until sugar is dissolved.

Wasn't sure where to post this, hope this is ok.
