That looks like fun, and SO goooooooo-oood. I love homemade jam. Canning is a fun thing to do. You might try cooking down the fruit in a crock pot for a day or three, it thickens is up to whatever consistency you want, and then you don't need as much sugar. Or any at all. Though you need to hot water bath-can it in the end. But it is tasty tasty. Good luck, and have fun (today?) with your next batch. (I"m so far behind on here.) Have a nice weekend.
