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

    Hello! I am very excited to try this recipe out. It’ll actually be my first time making jam.

    I was wondering if it is possible to make without adding any sugar? Or how does the sugar effect the cohesiveness of the jam if I were to add less?

      Hi Jamie, the sugar helps to preserve the jam. You can add the sugar to taste as some plums are naturally sweeter than others but if you want to store it on the shelf, you should not omit the sugar or cut it down too much.

      Hi Cathy, my mom has canned apricots using this method. She said she likes the apricot jam to be more chunky so as soon as it boils she turns it off and then lets it cool. She does it 6 times total with apricots so they thicken up while maintaining more of their chunky shape, but you can also follow this same plum jam method with apricots if you like and it will turn out great 🙂

      Yes :). Plums contain large amounts of natural pectin that is released and with bringing it to a boil several times, you are also getting rid of some of the plums juices to help it thicken up.

    Would you get the same effect if you cooked on low in crock pot? I made some pear butter that way.Also,what difference would it make if you use natural brown sugar instead,would it turn out the same?

      Hi Sylvia, 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. Also, I haven’t tested with brown sugar but I think it could work, although it might have a slightly different flavor with the added molasses that is in brown sugar. If you test either of those out, let me know how you like it 🙂

    Great recipe! I used yellow plums from my back yard tree. However,on the oven canning, should the lids have been sucked in while in the oven, or will that happen later? I just took mine our and the lids seem flat still. I’ve inverted the hars and had a bit of leakage from each on first inverting. They are presently inverted on the counter and the liquid in each jar is still boiling. Do you think the lids will become concave during this phase? Or perhaps I didn’t leave them in the oven long enough or tighten the lids enough?

      Hi Zach, they should have formed the seal in the oven. If the cans leaked when you inverted them, you probably did not tighten the lids enough. They definitely should not be leaking. Also, I’m not sure how far you filled the cans but if you overfill and don’t leave a little space at the top, it may not form the correct seal.

      Hi Terri, I didn’t measure it that way and it depends on the size of your plums. 1 lb for me was about 6-8, two-inch-wide plums. I want to say it was about 30 cups… maybe?

      Hi Florentina, It’s really difficult to guess without making a batch and measuring exactly and it also depends on how sweet your strawberries are. I think it would be safe to start with the proportions listed in this recipe and add more as needed. Strawberry jam would probably be good with a little fresh lemon juice also.

      Kathy, I am type 2 diabetic too and I make not plum jam but the traditional Polish version called “powidla”.
      There is no sugar added. It agrees with my diabetes just fine.

      As many traditional recipes, this one takes a lot of time and work but very little ingredients. Basically plums, preferably late autumn ones, small and sweet, but any other ripe plums will do.

      You just have to cook pitted plums for 3-4 days (more juicy plums take longer), about 4 hours a day – bring to boil that turn to low heat. Than let it cool in between.
      At some point it’s more frying than cooking. Takes a lot of stirring, because from day 2 it can burn easily (if it burs, transfer to another pot avoiding scraping the burned bits from the bottom, they will be bitter).
      Sounds tiring but it’s worth all this work.

      At the end, when it’s all cooked, you may add some sweetener. I suggest stevia. Powidla are sweet and tart, stewia is a bit insipid, goes well together.
      But sucralose is fine too.
      Don’t use acesulfam K or aspartam – it gives the worst aftertaste to plums. I’ve made that mistake once. 5 kilos of plums into the drain. Uneatable.

      When it’s cooked and sweetened, just bring it to the boil one last time, transfer searing hot to the jars, close lids very tightly and stand upside down on a kitchen towel until they are cool.

      Than enjoy!

        I forgot to mention that traditionally you don;t add any extra sugar to powidla. The natural sugars in plums should be enough and that tart hit is what makes real powidła.

            We use powidla like jam. Great with home made sourdough rye bread but with toast too. Good for pies, but with sweet crust – powidla shouldn’t be actualy very sweet and thay make lovely contrast with sweet crust. I always make two batches – sweetend and unsweetend. My husband likes them sweet. I like both. For pies unsweetened are best.
            There is a very popular Polish cake made with powidla. It has a peculiar name that means ” mold cake” but no mold in it. ☺
            I can put here a recipe if you don’t mind?

      I make homemade applesauce all the time with no added sugar. I use a variety of 4 to 5 different apples with an equal number of each type and it turns out wonderful. The trick is to use both sweet and slightly tart apples (no Granny Smiths). The last batch I made had Cameo, Fuji, Golden Delicious, Jazz, and Red Delicious. I use the traditional water bath canning method.

      I will be trying this plum recipe over the weekend…

    As a newbie to jamming and canning I was in search of a way to quickly use approx 4-5lbs of plums I got in my CSA this week. This recipe looked simple and didn’t contain pectin – which I thought was awesome. My husband mentioned making the jam in our bread maker so I looked at the bread makers recipe book and their recipes also didn’t contain pectin – just fruit and sugar so I tried it. The bread maker’s jam function is about 1hr 15 min long. After initally canning everything I decided it was too sour and too runny, of course. But then I decided to run the jam function again and add more sugar to taste and it worked. The jam got thicker and sweeter, so I did it one more time and was happy with the result after the 3rd session so I canned it. So if boiling intimidates you, try using your bread maker. It was so easy no worry about scorching the jam or stirring constantly. The color is great too
