Easy Rhubarb Jam Recipe with Pineapple

Looking for another great way to use rhubarb? Here are two easy recipes for rhubarb jam. Both of them yield delicious results, and both have a surprise ingredient. Get the simple instructions here and learn how to make it today.

Rhubarb Returns Faithfully Every Year

In my continued quest to use the produce stored in my big freezer from last year, I used some frozen rhubarb to make pineapple rhubarb jam. I’ve written before about my favorite ways to use frozen berries, but I’ve not yet written about rhubarb. Rhubarb is one of the most faithful returning plants in my garden. Planted years ago by my husband, it resides near the berries in the row of permanent plants in the vegetable garden. Our rhubarb plant is quite vigorous and large. If you are interested in growing rhubarb, check out this list of rhubarb’s best companion plants. You might find that a rhubarb plant would make a great addition to your garden.

I’ve had people tell me they could not grow rhubarb, and I’m always surprised by that. We literally have to do nothing to our rhubarb plant. If you want to feel like a successful gardener, try rhubarb. Ours seems to thrive on neglect. If you have some rhubarb you need to use, this easy rhubarb jam recipe is for you!

Uses for Rhubarb

If you have never tasted rhubarb, it’s quite sour. I compare the flavor to sour citrus, but there is something distinctly unique. It is often combined with strawberries or some other sweet fruit in crisp recipes. This rhubarb recipe, in addition to the pineapple, has another sweet surprise to tame the rhubarb’s tang. How do you thicken rhubarb jam? With strawberry jello! I actually have two variations of this easy rhubarb jam recipe to share with you today. I used frozen, chopped rhubarb, but you could use fresh, if you have it.

The Backstory of These Easy Rhubarb Jam Recipes

My dear, late mother-in-law had a close friend who shared recipes. That friend has now passed away, and I’m so thankful that I was the recipient of these excellent recipes she shared. Both recipes have similar ingredients. One calls for more rhubarb and takes less stirring time (Easy Rhubarb Jam Number 2). Easy Rhubarb Jam Number 1 calls for an entire can of crushed pineapple, and I would rather use up a whole can of something. If there is a partial can of something left, I sometimes have trouble finding ways to use the remainder. Anybody else have that issue? You can decide which one of these recipes looks best to you.

Supplies

This easy rhubarb jam recipe is ideal for canning. Each recipe variation makes about 6 half-pints, so here is the equipment you need to assemble beforehand. You will need:

6 half-pint canning jars, lids and bands

 

A large boiling water bath canner

 

A small metal saucepan with lid (for heating the jar lids)

A large stockpot

A large ladle like this one (for putting the jam into jars)

1 set of canning tools (optional, but these sure have made canning easier) 

 

Preparation

Set six canning bands (some call them rings) aside, near where you will be filling the jars.

Place the six glass jars in the water bath canner. The water should cover the jars by at least an inch. Turn the heat to medium-high.

Place six jar lids in the small saucepan with enough water to cover the lids. Cover the pan and heat the water on low. I’ve always been told not to let the water come to a boil. Now it’s time to make the easy rhubarb jam!

rhubarb jam recipe ingredients
Gathering the ingredients for the easy rhubarb jam recipe

Ingredients for Easy Rhubarb Jam Number 1

5 cups rhubarb, chopped into 1-inch pieces (or smaller, if you prefer)

5 cups sugar

1 cup water

1 20-ounce can crushed pineapple, drained

2 3-ounce boxes strawberry jello

Directions for Easy Rhubarb Jam Number 1

Chop rhubarb stalks into 1-inch (or smaller) pieces. Do you have to peel rhubarb for jam? No, and that’s a huge plus. Combine the rhubarb, sugar, and water in the large stockpot.

rhubarb jam recipe chopped rhubarb

Bring to a boil over medium-high heat (if you are in a hurry, you may turn the heat up to high, but keep stirring). Boil hard for ten minutes, stirring constantly. The mixture will thicken and have a syrup-like consistency.

rhubarb jam recipe cooking

 

Drain the crushed pineapple and add to the stockpot. Return the mixture to a boil. Boil for five minutes. Remove from stove and stir in two boxes of strawberry jello. Stir until the jello is dissolved. Makes 6 half-pints.

Filling the Jars

Using tongs, if you have them, lift hot jars out of hot water. I usually place mine in the sink. Next to the sink, I place my trusty wooden breadboard. You can use a cutting board or something similar to protect your counter. Bring the pot of hot jam over and place it next to the jars. Ladle hot jam into jars, leaving 1/4 inch headspace. Once all jars are filled, wipe jar rims.

rhubarb jam recipe without lids

Place lids on jars and place bands on jars. Adjust until they are fingertip tight.

Processing the Filled Jars

Place jars (using a jar-lifter, if you have one) in the hot water bath in the canner. Water should cover the jars by at least one inch. Bring the water to a boil and process the jars for 15 minutes, adjusting for altitude. When processing is done, remove the jars (again using a jar-lifter, if you have one) and place on a towel to absorb the drips and to cool.

Checking the Seal

If all has gone as it should, you should hear the jars seal as they cool. When they are cool, press the center of each lid. They should not flex. Label and store the jars in a cool, dry place. The quality is best if used within 18 months. Refrigerate any jars once opened. So delicious!

One Last Quick Tip

Sometimes, I look on the pantry shelf and only have pineapple chunks instead of crushed pineapple. Has this ever happened to you? Here’s my quick solution: Drain the pineapple juice from a can of pineapple chunks. Quickly process the chunks in a little mini-food chopper, like this one.

 

I received a chopper like this for a wedding gift, and have used it many times over the years. It’s very handy for chopping nuts as well. If someone asks you for a wish list at Christmas or for your birthday, this is a handy little kitchen gadget to keep in mind.

    Thank you so much for this easy rhubarb jam recipe. Even people who hate rhubarb love this jam, ie. my grown children! I am so happy to be able to use more of my rhubarb as it came from my Dad’s garden in Connecticut all the way to Colorado on an airplane in my checked bag after he passed away. I thought it hadn’t made it through the winter that first year but I was thrilled to see it pop through the snow! It’s a wonderful reminder of my Dad and his garden.

    • What an inspiring story of how you came to have rhubarb growing in your garden. You are welcome for the recipe. I am blessed to be able to look around and see plants in my garden that were given to me by dear ones who are no longer with us. I agree, it is very special.

  3. Thanks for this recipe. I made it today, I’ve never heard of jam made with jello just pectin. Excited for the turnout! How long does it take to thicken?

    • The rhubarb jam should be fully thickened when cooled to room temperature after the canning process is complete. Hope this helps!

  6. So there is no need to over tighten the rings?

    Reply
    • No, just finger-tight. I know the canning kits come with jar band wrenches, but I have always read that there is no need to tighten more than with just the usual strength of your fingers.

  7. Just asking..can sugar free jello be used in making jam??

    Reply
    • Great question! I think it should work, because the reason for the jello in this recipe is not for its sugar content but for its thickening properties. The recipe already has a lot of sugar in it, so I think you should try it. I never have, so if you do try using sugar-free jello, would you mind reporting back to me with the results? I’ll add your question and answer to my blog post after you try the experiment. Thanks in advance for testing it out.

  8. Can I steam can this recipe? I am new to canning and I was advised that somethings HAVE to be water bathed. Thanks! I am an avid rhubarb consumer. I have 2 beautiful plants that have made me some beautiful pies, custard tarts and cookie bars, but I am looking to expand in to jams. Thank you so very much!

    Reply
    • By steam canning do you mean pressure canning? Here’s some info I found from PickYourOwn.org: “You should be water bath canning jams and jellies, not pressure canning. … If you only have a pressure canner, don’t fret: you can use your pressure canner as a water bath canner; just don’t seal it up, so it does not pressurize. And then only 5 minutes in the canner. Jam only needs 5 minutes, no more than 10!” I hope your rhubarb jam is a great success!

    • Can I just use the whole can of crushed pineapple with the juice and no water or will this mess up the recipe?

      Reply
      • What I would do is drain the crushed pineapple into a measuring cup to see how much juice you get. If it’s less than one cup, add enough water to make one cup, then add to the pot. That’s a good idea, and a great way to use the juice.
