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.

Natasha's Kitchen Cookbook

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

    Just picked our plums yesterday…again. I think its the last of them. My husband and I have decided to make plum jam. Your recipe looks soooo easy, we’ve chosen it. One questions first: In between each boil, do we wait for the jam to cool to ‘room tempeture’ through and through? Do we stir it during the cooling process?

      It can still be warm and not fully to room temp. You might stir it soon after you turn it off to make sure it doesn’t scorch to the bottom but you don’t have to keep stirring while it cools. Hope that helps! 🙂

    IT is sooooooo sour! I spent all day pitting plums I hat to throw it away.
    Its day #2 now. I used 12 lbs of plums and 5 cups of sugar and one cup of agave nectar now and it is sooo tart. any suggestions?

      You must have had some very tart plums! Did you try them before you put them in? Were they sour? It’s best to use ripe plums when making Jam. I don’t know what else to tell you besides adding more sugar if you used plums that are tart…

      I would guess that you are using softer/juicier Santa Rosa or Beauty plums. They are more pink than the plums pictured here. I typically use 8 cups plums to 5.5 cups sugar with my Santa Rosas and that’s still on the tart side because I like to taste the fruit flavor rather than sugar. With jam you should always taste it as you go to check the sweetness, and you can always empty your jars back into the pan, add more sugar and boil it again before resealing with new lids in clear/sterilized jars.

      I think it has everything to do with the skins. Unfortunately I have the same problem. The flesh of the plums I used was very sweet, but the skins were a tad bitter, which really comes out in this process. I’ve added a LOT of sugar, and I think this is just going to be a wash. It’s more like a sweet-tart cranberry sauce, though I hesitate to say tart; it really is more bitter.

    Great for cooking with kids, save the seeds, clean, wash, dry and germinate in brown bag in the refrigerator. Two months later, plant baby plum trees for gifts with jam by the holidays!

    The name of the plum tree is Santa Rosa Plum, they are very common in California. I was just gifted about 30 lbs of plums yesterday. Jam making will commence in a couple of days when they are fully ripe.

      They do not really self-seal, you need to boil them to melt the sealant thoroughly.The jars are not sterile any more by the time you fill them and wipe the rims. Don’t take chances with your family’s health. It is worth the extra ten minutes of your time to keep them safe.

        Jam sounds wonderful Natasha, but you need to correct the spelling of “plums” throughout your recipe. “Plumb” is a term used in construction; like “a wall is plumb.”

      Inessa – We used to get loads of pears from our neighbor who grew them commercially. We canned and dried them, and made pear butter. Pear butter is made just the same as you would apple butter. To make canned pears, just peel them, keep in lemon juice until all are peeled and cored, put in jars, add any juice to the jars, cover with water and waterbath for 20 minutes (this is at 5400 ft altitude -adjust accordingly to your altitude). To dry the pears we quartered them length-wise, peeled, cored, rinsed in a lemon juice/water rinse to keep from browning too much, then dried in a food dehydrator. They are a wonderful snack.

      Inessa, I realize that this is way after the fact, but you might want to know this for the future. Pears by themselves make a kind of bland flavorless kind of jam. My Mom always made Pineapple Pear Preserves by combining the two fruits. It was pretty good, but other jams have more flavor.

      Make pear-sauce. Instead of apple sauce. It is delicious! Peel n core the pears n place in a large pot. Add 1cup of sugar and however much cinnamon you like. Boil them untitled soft and mash with a potaoto masher to break up. Place in sterilized quart jars and water bath(boil) for 20 minutes. We love it!

      Oh thank you. Sounds like I have fancy plums and didn’t even know it! Cooking it several times thickens it without turning the fruit into mush 🙂 Technically you could just do it once if you were satisfied with the consistency. Good question!
