I've canned 12 + cans of rhubarb juice! That alone took 6 lbs. Then I had another 6 lbs I made freezer jam with! (and that was just 1 rhubarb bush). I mixed some with strawberry, some with raspberries and some with pineapple. It all taste great! The rest of the ingredients are sugar (lots) and a little bit of water and some lemon juice. Boil it and mash it. Easy. Yummy. Fresh.

Tip for freezer jam: When you put it in a freezer bag; lay it flat, that way it takes up less space in the freezer.
