Rhubarb Jelly is a low-sugar cooked jelly made with Pomona’s Pectin. Pomona’s Pectin contains no sugar or preservatives and jells reliably with low amounts of any sweetener. See below for where to buy.

Yield: 4 to 5 cups

Before You Begin:
Prepare calcium water. To do this, combine ½ teaspoon calcium powder (in the small packet in your box of Pomona’s pectin) with ½ cup water in a small, clear jar with a lid. Shake well. Extra calcium water should be stored in the refrigerator for future use.

Rhubarb Jelly Ingredients

1 pound trimmed & washed rhubarb stalks (to make 4 cups unsweetened rhubarb juice)
4 cups water
2 teaspoons calcium water
¾ cup up to 2 cups sugar
5 teaspoons Pomona’s Pectin powder

Rhubarb Jelly Directions

1. Wash jars, lids, and bands. Place jars in canner, fill canner 2/3 full with water, bring to a boil. Turn off heat, cover, and keep jars in hot canner water until ready to use. Place lids in water in a small sauce pan; cover and heat to a low boil. Turn off heat and keep lids in hot water until ready to use.

2. Slice rhubarb stalks crosswise into one-inch pieces. Place rhubarb pieces and water in a sauce pan and bring to a boil over high heat. Cover, reduce heat, and simmer for 15 minutes. Remove from heat.

3. Strain liquid through a fine-mesh strainer into a pitcher or spouted bowl. Press on the solids to extract as much juice as possible.

4. Let juice sit for 20 minutes. The juice will separate, leaving a yellowish sludge at the bottom. Pour off the clear pink liquid into a large measuring cup, leaving the sludge behind. Discard the sludge.

2. Measure 4 cups rhubarb juice into sauce pan.

3. Add calcium water and mix well.

4. Measure sugar into a bowl. Thoroughly mix pectin powder into sugar. Set aside.

5. Bring juice mixture to a full boil. Add pectin-sugar mixture, stirring vigorously for 1 to 2 minutes to dissolve the pectin while the jelly comes back up to a boil. Once the jelly returns to a full boil, remove it from the heat.

6. Fill hot jars to ¼” of top. Wipe rims clean. Screw on 2-piece lids. Put filled jars in boiling water to cover. Boil 10 minutes (add 1 minute more for every 1,000 ft. above sea level). Remove from water. Let jars cool. Check seals; lids should be sucked down. Eat within 1 year. Lasts 3 weeks once opened.

Option: If you want to put lemon juice in your jelly, you can add up to ¼ cup for 4 cups of Rhubarb juice. Add the lemon juice in Step 3.

4 thoughts on “Rhubarb Jelly

  1. Hi, I am wanting to make Rhubarb jelly, but would like to add some Strawberry juice also. Two part question:
    Would you do 2 cups of Rhubarb Juice and 2 cups of SB Juice, or would you do 3 cups of Rhubarb Juice and 1 cup of SB Juice? I want to be able to taste the Rhubarb and the SB might overpower it. I think the color of the pink and a little of the SB juice, would be really pretty.
    Second part, most of the recipes I’ve seen for jelly from juice calls for 4 tsp of calcium water and 4 tsp of pectin. This one calls for 2 tsp of calcium water and 5 tsp of pectin. Can you confirm this is what you would do with the Rhubarb and Strawberry juice combination. And do I need lemon juice at all?

    • Dear Shelley,
      If you want the Rhubarb to dominate, I would suggest 3 cups rhubarb juice and 1 cup strawberry juice. The color of your final product will depend on the color of your rhubarb (some are red and some are green) and how red your strawberries are. So many strawberries are white in the middle these days.

      Rhubarb fruit and juice do require less calcium water. Strawberry juice would take the normal amount of calcium water — 1 teaspoon per cup of juice. So you need to do the math depending on your ratio of juices.

      1/2 teaspoon calcium water for each cup of rhubarb juice and 1 teaspoon of calcium water for each cup of strawberry juice.

      Do the math also with the pectin amount: 1 1/4 teaspoons pectin per cup of rhubarb juice; 1 teaspoon of pectin per cup of strawberry juice.

      Lemon is not required for either rhubarb or strawberry; it is optional.

      I hope this helps — and happy jamming!
