How to Can Rhubarb Jam

Be prepared for a few – ok, a lot – of rhubarb recipes. Maybe you aren’t as used to this spring fruit (which is actually a vegetable) as I am. But growing up in southeast Iowa, this is such a common staple spring item. The garden sends forth so much and in order to be economical, people found many ways to use it: a la, this rhubarb jam!

Thankfully I love it and I hope you learn to appreciate it as well, if you aren’t used to it already. This is my grandma’s amazing rhubarb jam. Any jam is good, but this one is special. A secret ingredient of orange slice candy flavors and gives body to the jam, making it one of a kind.

How to Can Rhubarb Jam

  • Author: Kaleb Wyse
  • Prep Time: 20 minutes
  • Cook Time: 30 minutes
  • Total Time: 50 minutes
  • Yield: 7 jam jars 1x
  • Category: Jams
  • Method: Canning
  • Cuisine: American

Description

While rhubarb may not be that sweet, this jam definitely is! The tart flavor of rhubarb is mellowed with the addition of sugar and is a great, spreadable texture!


Scale

Ingredients

  • 8 cups rhubarb, chopped
  • 4 cups sugar
  • 1 pound orange slice candy, chopped finely
  • red food coloring

Instructions

  1. Place rhubarb and sugar in large heavy-bottomed stock pot or jam pan. Bring to a rolling boil: a boil that cannot be stirred down with a spoon. Boil for 5 minutes.
  2. Add prepared orange candy and boil for an additional 5-10 minutes until the desired consistency is reached. This can depend on the boil’s strength.
  3. Depending on the variety of rhubarb, the resulting color can be undesirable. To liven this up, add 3-5 drops of red food coloring to give a red tint.
  4. Test the consistency by placing a small amount of jam on a plate and put it in the freezer to cool quickly. After a minute or two, remove to see how firm and thick the jam is.
  5. Ladle hot jam into prepared jam jars. Clean rims with hot water and place on lids and rings. Put in boiling water bath for 10 minutes. Remove and let sit undisturbed for 24 hours.

Notes

Soon after removing the jars from the water bath, you should hear the “ping” of the jars sealing, which is such a good feeling!
