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 just wanted to thank you for this recipe. It has been my go to for the past several years when the plums are nice and ripe on the tree. This year, I picked some too soon, and it turned out quite sour. No worries though! A couple of weeks later I picked more, on the 3rd boil added the sour batch. It turned out heavenly as usual.

    Hello Natasha. Thank you so much for sharing your recipes 🙂

    Can you add Lemon juice in it (like you added in your peach preserve & i did see another recipe with Lemon juice) ?

    What is the purpose of lemon juice ?

    Thank you 🙂

      Hi Sofie, the lemon juice is for flavor and adds some acidity which helps in preservation. The peach preserves did not really have any tartness from the skins so adding the lemon juice really enhances the flavor there. I’ve never found it necessary with plums. If you have a variety of plums that are ultra sweet (including the skins), you might add some lemon juice. It really is also a taste preference – it won’t spoil your plum jam to add some lemon juice 🙂

    Hi Natasha! I already made your peach jam, my plum jam is in process and I wonder can I use this recipe to make pear jam. I have found some pear jam recipes online though they call for too much sugar. Like 3 lb of pears and 4 cups of sugar.

    Thank you!

      Wow that is a crazy amount of sugar!! I haven’t tried this with pears so I can’t say for sure. I would probably add sugar to taste, but pears are pretty sweet naturally (not tart at all) so I’m not sure why anyone would add that much sugar. If you experiment, let me know how it goes 🙂

    This was my first ever jam making experience! Turned out excellent. My Mom said it was the best plum jam she has ever tasted (and that means a lot!) I added about 1 tsp of cinnamon as the mixture was reducing and boiled a total of 5 times. Love all your recipes 🙂

I just picked a half bucket so am going to make this jam today. Thank you so much for the recipe It looks so yummy.

    Oven canning is not considered safe by the USDA, nor is steam canning. Ovens constantly cycle on and off, so the temperature fluctuates. Even a new oven can be out of calibration, and they all have hot spots and cool spots. The safest and most reliable way to make a jam shelf-stable and ensure a proper seal is to use a boiling water bath. Freezing is also an excellent option, if you have the space. For information, see the National Center for Home Food Preservation website,

      Thanks Laurie, I do have a note about this at the bottom of the post, but thanks for sharing! This is my Mom’s and Grandmother’s method :). I’ve seen 2 different methods with the water bath – one where you don’t over-tighten the lids and fill the pot to 1″ below the top of the jars and one where you tighten the lids so the water doesn’t get in and fill the pot 1-inch over the top of the pots. Which method do you use?

    Natasha, thank you so much for the Plum Jam recipe. Tastes just like my grandmother’s “pavidel.” Glad to carry on the family traditions!
    Also, just made some Peach Jam, but it turned out a bit too sugary, and seemed to crystalize around the pot. Looked and tasted fine, but seemed to grainy. Any suggestions?

      Hi Linda, I’m so glad you enjoyed it! I’m not sure why it would be grainy or crystalize around the pot the way you described. Could the heat have been set too high? Also, did you allow the sugar to dissolve into the peaches at the beginning? If it was too sweet, it may just be that you had sweeter peaches than mine.

    Is it safe to not add lemon juice? Other recipes I’ve read it’s needed to help preserve in case the plums are lower acidity. I water bathed numerous jars, Just curious what the shelf life is? I’ve done 15 pints and the jam is fantastic! I added 3 cups sugar to 4-5lbs though so I didn’t boil as many times.

    Natasha..
    Hi there! I am making my first ever batch of jam and I am using your recipe! My new property has some wild plums and I just had to use them! Their skins tend to be pretty tart but I think I have the honey right to counter that.

    I am on about my 4th boil and the skins aren’t as ‘dissolved’ as I think they should be. However, I just don’t know what is right?

    Can you ‘mash’ these in some way or is that a no no? Is there a way to tell if skins are ‘okay’ to put into jam?

    I know it has been a few years since you wrote this. I have googled everything and just hoping you might reply:-)

    PS>..I will write back to rate when I am done:-) But, I can tell it is going to be good!
    Thanks!

      Hi Renee, it really depends on the variety of plums. There are some plums with thicker skins but I think the skins add nice texture to the jam. It would be ok to mash it if you wanted it to be more of a puree consistency but we prefer it slightly chunk. I like seeing the pieces of fruit in my jam 🙂 I hope you LOVE it! 🙂

      Hi Linda, the lids should be on tight enough that you don’t have to tighten them additionally but if they are too loose, they should be tightened. I’ve had to tighten them before 😉

    We live in a mobile home park and the owner’s wife brings us these plums every year. She calls them Italian Prune Plums. What I don’t use for jam I pit and quarter them, freeze on a cookie sheet, then bag to use for plum crisp or Kuchen.

    Absolutely delicious! I made it with small golden plums and cooked it a total of six times.
    I was skeptical of how well the peel would cook down but it just becomes a wonderful consistency.
    I love the low amount of sugar and as a result how much of the plum sweetness shines through. Next time I might even try it with a bit less sugar.
    I will certainly be using this as a my base plum jam recipe from now on. I am excited to experiment with some add in flavors!

    Two questions:
    1. How often do you spoon of the foam – each cook or just the last one?
    2. Do you need to bring the jam up to 220F on the final cook or the does the process of multiple cooks negate the need for a certain temperature?
    Thanks and looking forward to making it!

      Hi Laura, we actually don’t spoon off the foam usually. Its tempting but not necessary. Also, with each cook, the jam gets to the boiling point which is above 120. I hope you enjoy it!

    When canning, as long as the inner lid (the flat part) is tightly sealed after you process it your product is fine. After the jar has cooled I always take the ring off (that’s the part you screw down) and lift each jar by the lid (the flat part). As long as that holds I know it has sealed. If it doesn’t hold then I water bath it again.

    For 12 lbs of plums you used only 4 1/2 C sugar, or about 2 pounds — less than 20 percent the weight of the plums. Usually recipes call for 55-60 percent sugar for jelling and safe preservation. Is it the repeated boiling that allows you to use so little sugar? That’s a big plus in this recipe. I live in France and would like to try this with Damson plums (known here as quetsches). By the way, those look like Damsons you used. Are they a bit sour?

      Hi Jeanne, yes the repeated boiling and reducing it down is what allows the amount of sugar in the recipe. You can use more sugar or add it to taste for more tart plums 🙂 My plums were sweet. The skins were just barely tart but overall, I would say they were sweet plums.

        Hi Natasha,

        I went ahead and experimented with using apples and the process was a tad bit different. I used golden delicious apples and added some lemon juice, cinnamon, and vanilla with the sugar. Because apples were hard to mash in the pot, I ended up pureeing all the ingredients together. This reduced the cooking time a lot due to the texture! Overall, I ended up making apple butter and it was so good!
