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

      Hi Suzanna, since there is no pectin, it needs time to thicken.

    Once a jar is opened how long should it last if kept refrigerated?

    Thinking of maybe using 250ml jars instead of pint size.

      Hi Cheryl, There’s a lot of sugar to keep it preserved even after its opened. I’d say a couple of weeks in the fridge

    Just wondering why you have to boil it, cool it, boil it, cool it, etc. Couldn’t you just simmer it to the desired consistency and be done with it? What’s the effect of boiling it in stages, bs all at once?

      Hi Linda, if it is heated for too long, it can scorch on the bottom and can turn a very dark color.

    Hello I’m about to start making this jam and I am wondering without the pectin how long will it stay shelf stable in the cupboard? Do I have to keep it in the refrigerator and how long will it last? I understand it lasts up to 3 months if the jar doesn’t seal but otherwise if everything is sealed what is the lifespan?

      HI Laurie, it will keep at least a year and usually longer, just like any jam if it is processed in a water bath correctly.

        Can you clarify the quantity this makes. Initially the recipe says 5-6 pints, and then later it says 8 jars. And you use the ambiguous term “pint.” Is that a 16 ounce American pint or a 20 ounce Imperial pint (which is still used in Canada)?
        I have completed the first boiling/simmering, and it looks good so far!

    I have a tree FILLED with Italian prune plums, and have been desperately trying to find recipes to use for enjoying them throughout the year. I’ve tried a few preserves recipes, and this is BY FAR the easiest and best tasting! It is now my go-to for preserves. Just delicious — perfect flavor, not too sweet, and just the right texture to the preserves.

    I am confused…why does the recipes with pectin call for 4 lbs. of plums to 8 1/2 cups of sugar. Your recipe has 3 times the fruit to half the sugar. Am I missing something?

      Hi, since we boil down the mixture several times, the flavors will be concentrated, and there is no need to add that much sugar.

    This is the time of year it seems everything needs to be preserved at the same time.

    I like this recipe for a few reasons: 1) You can take your time; 2) it works; 3) it tastes good; 4) I’m in control of the Preserve’s consistency; 4) did I mention I’m not rushed?

    Have you used this method on other fruits, i.e., strawberries, raspberries, peach, etc.?

    Thanks for sharing.

      Hello Natasha,

      You say Plum Jam (No Peel, No Pectin) but no where have you said how the peel is removed. It does seem lovely otherwise and I like the idea of simmering it in stages and eventually it thickens.

      Must try, thanks very much,

    Never done this before, and will be using plums from our own tree

    I noticed that there is no water or liquid added
    Is this correct?
    Other jams we have made years ago had water added

      The jam may be looser, as berries do not have much natural pectin compared to stone fruits.

      Also in English the plum name is Damson I believe and we used to have them also! They are my favorite variety! I don’t think I even liked plums before I ate these!
