What You’ll Need For Ingredients

Rhubarb: This tart, vibrant stalk is technically a vegetable; it’s one of the few that are almost always used like a fruit. 

Sugar, Salt, Water, Vanilla Extract: Once boiled, this mixture helps break down the rhubarb into a sticky, jam-like sauce, balancing out the tartness of the rhubarb.

Karlynn’s Tips and Tricks for the Perfect Rhubarb Sauce

  • Look for firm, crisp stalks: When choosing your rhubarb, you want firm stalks with a good red color to them. The more vibrant the red, the more “ripe” the rhubarb is.
  • Never use the leaves: This kind of goes without saying but the leaves of the plant are toxic so please do not use them in any way shape or form.

Storage Instructions

Refrigerate: Rhubarb sauce will keep well in the fridge for up to a week if stored properly in a glass jar with a tight-fitting lid.

Freezing: You can also freeze it! Rhubarb sauce freezes beautifully and can keep for up to 6 months. Just thaw in the fridge overnight before using.

    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.

  2. 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!

  3. 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.

  4. 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.
