For many years, I’ve been trying to make my mother‘s Rubarb sauce by memory with no success. This recipe did the trick. Spot on.

Should You peel the stalks?
Kathy Huizenga says
My finished rhubarb sauce is green. I’m guessing that’s because your rhubarb maybe had more red in it than mine. But it taste delicious. Can’t wait to try it on ice cream!
Rose Bowler says
Almost identical to how my mother used to can quarts of rubarb fruit little more sugar little more water canned in a water bath. Served in winter after supper in fruit nappies. A good treat on a cold stormy winter night on the farm.
Kathy says
When I was a small child my mom would make this and give it to me when I was sick. I still (at 70) love rhubarb especially mixed with strawberries baked as a crisp.
