Rhubarb Ketchup

I received this recipe from a friend about 15 years ago. It's a nice surprise for ketchup lovers, and so easy to prepare. The spicy flavor makes this one of the tastiest ketchups I've ever had! —Faith McLillian, Rawdon, Quebec
  • Total Time

    6-7 cups

  • 1 cup white vinegar
  • 2 teaspoons salt
  • 1 teaspoon ground cinnamon

If using frozen rhubarb, measure rhubarb while still frozen, then thaw completely. Drain in a colander, but do not press liquid out.

    Loved the flavor! Not ketchup though. I cooked on low for 3 hours and it still isn't that thick. Will use whenever a recipe calls for chili sauce and on top of meatloaf as well. I also used my immersible blender to smooth it out.

    The pickling spice over powered everything, will not be making again.

    This recipe is fantastic!!! My daughter who puts ketchup on everything loves it. I did use one reviewers suggestion to use the immersion blender to smooth it out. It's great and has become our replacement for good old tomato ketchup.Thanks for sharing!!!

    After cooking the sauce down a bit, I used an immersion blender to smooth it out a little. It is absolutely wonderful with turkey burgers.
