We’re on a canning spree this week. The air is crisp and the mornings are cool. We’re surrounded by a fiery array of leaves that rustle in the warm afternoon breeze. Fall is in the air and canning just feels right this time of year.

I could eat this plum jam by the spoonful; paired with a hot mug of tea (I’m totally day dreaming here)… Our tiny plum tree overproduces the most amazing little plums every year. I wish I could name this variety; anyone recognize these little beauties?

This recipe is really a cross between plum jam and plum preserves. It still has some of it’s preserve-like plum chunks, but it’s nice and thick and spreads beautifully. It’s awesome paired with breakfast pancakes or crepes. Oh and this would make the sweetest Christmas gift!

How to Make Plum Jam:

Cooking the Preserves:

1. Cut 12 lbs of plums in half, pit them and place in a large mixing bowl. Drizzle well with 4 1/2  cups sugar. Using a large spoon, stir plums with sugar until all are coated. If your plums are overripe or already very sweet, you may only need 4 cups of sugar total. You can add more sugar to taste while its cooking. Let plums sit at room temp with the sugar for about 1 hour, or until sugar is somewhat dissolved.

2. Transfer plums/sugar mixture in to a large cooking pot. Place it on the stove uncovered and bring to a boil, stirring occasionally. Make sure if you see a light boil to stir because the whole pot may not be boiling, just the center. If it stops boiling after you stir it, continue boiling until everything is uniformly bubbling, then simmer for 10 minutes and turn off the heat. Let the pot stand uncovered until it is just warm to the touch or reaches room temp.

3. As soon as it cools, repeat step 2 the same way – simmering 10 minutes. You will bring it to a simmer a total of 4 times, stirring to prevent scorching the bottom. This is why it takes 2 days to make. It’s really easy though and so worthwhile! There’s no “set” waiting time between boilings. If 2 days doesn’t work for you, by all means, take 3 days. Preserves have plenty of sugar so they won’t spoil at room temp if you leave it on the counter overnight. If you want the preserves to have an even thicker consistency, you can boil it 5-6 times if you wish.

(Note: the fourth time you boil, bring it to a boil over a little lower heat and stir a few extra times to prevent scorching. Also, it thickens more as it cools. If using a different type of plum, I suggest adding sugar to taste in case they are more tart)

4. The last time you bring it to a boil you will want to transfer it to sterilized jars while it’s boiling hot.

To sterilize the jars:

1. Start by washing your jars and lids with warm water and soap then let them dry in the oven at 215 for about 20 min or until completely dry. Boil the lids 5 min.

2. Transfer your boiling hot jam to the jars using a glass measuring cup and a funnel (least messy method) leaving about 1/2″ space.

3. Screw the lids on enough to keep a tight seal in place but don’t over-tighten them since air bubbles need to be able to escape.

Current Canning Guidelines:

Get up to date on the most recent canning guidelines here. It’s a great resource to answer frequently asked canning questions. Current guidelines recommend the following process (instead of oven canning):

  1. Place packed cans into the canning pot and cover with 1-2 inches of water. Bring to a boil and process 15 minutes.
  2. Remove from the pot and leave at room temperature undisturbed for 12-24 hours. You may hear a pop when the jars fully seal.
  3. After 24 hours, check that the seal has formed by pushing down on the center of the lid – it should not move at all. If the seal does not form, refrigerate jam and enjoy within 3 months.

Recipe updated in 2019 to reflect new canning standards. Previously we used the oven method: screw the lids on enough to keep a tight seal in place but don’t over-tighten them since air bubbles need to be able to escape and place in the oven at 350˚F for 15 min then carefully remove from oven, flip upside down and let cool to room temperature.

Signs of Spoiled Canned Food:

With any type of canning, we follow this advice: “When in doubt, throw it out”
Discard and do not eat or taste any canned food if you notice any of the following:

  • the jar is leaking, bulging, or swollen
  • the jar looks damaged, cracked, or abnormal
  • the jar spurts foam or liquid upon opening
  • the canned food is discolored, moldy, mushy, slimy, or smells bad

    I made this using a slow cooker! 2 hours on high covered, 1 hour on low uncovered, 2 hours on high covered, and finished with 1 hour on low uncovered. I told you I would let you know how it worked. It is a great way! I let plums and sugar stand at room temperature overnight, great results!

    Is it OK to add sugar right up to the final boil if required? I was not clear by the mention of adding sugar to taste whether you meant only during the initial prep of the plums.

      Hi Pat, it is ok to add sugar at the end and just make sure it comes to a full boil after adding the sugar to give it a chance to dissolve and reach a safe temperature.

      Hi Laura, yes that is the usual culprit is having the pot over too high of heat and a thinner bottom pot is most susceptible to scorching. If you haven’t stirred it already, you can salvage it (do not stir), but just pour it into a second pot. If you stir, the whole batch will have a burnt taste. I hope that helps!

      Hi Joan, I’ve never tried it in a slow cooker so I’m not sure if it would work. They cook on the stovetop without a lid so I’m not sure if they would scorch or how long it would take in a slow cooker. Some slow cookers can have hot spots. If you test that out, let me know how you like it

    Hi Natasha. Thanks for your site. Just found it! It’s in my favorites now

    So I’m trying the plum jam recipe, hoping it is better than others we buy at markets or specialty country stores. I find most are like jelly with no real plum.

    I’m a bit confused though with your recipe. I’m ready for boil #4 but the plums are still large pieces. I was expecting them to break down (similar to cranberries when you cook them). So question is, should I use my hand blender to smash them up a bit. It would be hard to funnel it into the jars the way it is – likely was going to scoop it anyway though, but for jam I’d like the pieces smaller.

    I never seem to get recipes right, though I keep on trying. So any advise you can give me is truly appreciated!

    Thanks
    Patricia

    PS looking forward to trying more of your recipes

      Hi Patricia, there are some varieties of plums that don’t break down as much as others. It would not hurt to use an immersion blender or even a regular blender to break up the plums to your desired consistency.

    Ok. I’m a guy. We have a plum tree. Plums were starting to fall off. I found this recipe online and figured I’d try it. Not only is it super easy but it’s awesome! I (your recipe) even received the stamp of approval from my wife who is an exceptional cook. Yup, i canned them too. Don’t tell my biker friends.

    I have tried this recipe a few times with mixed results. The first time is was very dry, the second time I only did two boils but the second was much longer – that one was good, and the third I just finished (four boils) finished so we’ll see. The one thing I find really confusing about this recipe is the two different methods of the last step – oven versus boiling. I did the boiling since that seemed to be recommended, but I also flipped the jars upside down since the description of the boiling method didn’t indicate whether or not to flip the jars. I think this recipe would be greatly improved if the “oven” method (and any associated photos) were removed completely so it is clear.

    Will my jam be harmed by having flipped the jars upside down after boiling?

      Hi Barb, the jam should not be harmed, just check that the seal has formed and the lids don’t pop when you push down in the center. I updated the recipe to make it more clear and thank you for your feedback!

        Thanks for confirming. I have another question: The first batch I made was very dry (I didn’t realize how much it would thicken after it cooled). Is there any way to “fix” those jars of jam? Would it make sense to address the problem each time we open a sealed jar, by heating it a bit and adding water?

        Thanks!

          It does thicken when it cools so it’s a good idea to chill a small amount to see how thick it will be and add some water if necessary before canning it. Once it is canned, I would not open the cans to fix it at that point but address the jars as they are opened.

            Yes, agreed – I don’t want to “re-can” them all. So to fix each jar as we open it, what should I do? Should I just add water, or would it be better to add water and heat the jam again to get the desired result? Thanks!

    Hello Natasha, I have around 2 kilos of plums – i.e. about 4.4 lbs. Reducing the amount of sugar proportionately means I would only use around one cup, which sounds hardly anything, given that most oother plum jam recipes call for almost equal amounts of fruit to sugar. How much sugar do you think I should use? Thank you.

      Hi Valerie, we have a handy tool to help you scale the recipes up or down. Click on the servings in the recipe card and then you can adjust the servings until you see about 4.4 lbs and you will see the sugar is about 1 1/2 cups. I would add that much and then add more to taste. Keep in mind there is no pectin because the jam becomes concentrated and has enough natural pectin to thicken so it is a more concentrated jam than the jam recipes that have added pectin.

    Hi Natasha,

    I made this and my family and my husband’s family absolutely love it! I have a ton of fresh peaches and was thinking of doing the same thing with the peaches(maybe less sugar and add lemon juice) , but I was wondering if you ever made peach jam the same way? If so did you add a certain amount of lemon juice or what was your strategy?

    Much appreciated!

      Hi Cindy, there is ample sugar to preserve the jam but if that is a concern for you, you can add lemon juice, but you will need more sugar to balance the flavors. I wasn’t able to find a recommendation for this – if you have come across something specifically for plums in the official canning guidelines, can you link it here? Thank you!

      Jen, you don’t need to bother with trying to measure out the fruit in cups. I have a kitchen scale. Like Natasha, I am using standard U.S. grocery store red plums about 2-inches wide. It came out to 6 plums per pound. So, 72 individual plums = 12 lbs.

    I love the results I got with 4-stage boiling/cooling. Wonderful! I left my batch super-tart. My question is: what’s the purpose of the oven step? Couldn’t I just fill the jars with boiling jam and go straight to the water bath, as I do with other recipes? I hope the oven step isn’t mandatory, because I already skipped it! But I’m still curious 🙂 Thanks for your delicious website!
