We’re on a canning spree this week. The air is crisp and the mornings are cool. We’re surrounded by afieryarray 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 largemixing 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 need4 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. Placeit 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 of4 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 soapthen 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

FAQs

What thickens jam without pectin? ›

How to remove skin from plums? ›

The skin is edible, but if you want raw plums without the skin, drop into into boiling water for around 15 seconds, then plunge immediately into cold water and it should come away easily. If you're cooking plums, they're easier to skin afterwards.

Do you need to pit plums for jam? ›

What happens if you don't use pectin in jam? ›

You don't have to, but proceed carefully. "If you are really anti-pectin, you can omit it, but you'll need to cook the jam longer. Doing so will remove most of the water content in order to get it to set up properly and in turn, will result in a smaller yield," adds Wynne.

Does lemon juice thicken jam? ›

Lemon is crucial to balancing those sweet flavors, but it also helps the pectin to firm up the jam. It can be added at the start of the cooking process or towards the end, but what must be taken into account is that adding liquids to the jam mixture will inevitably require the jam to cook for longer.

Is jam better with pectin or without pectin? ›

Strawberry jam with added pectin can be cooked in as little as ten minutes, preserving that fresh berry flavor and quality. Strawberry jam without added pectin needs to be cooked up to four times longer to reach the gel stage, resulting in a much sweeter, less fresh-tasting jam.

Is plum better with or without skin? ›

The skin of the plum is safe to eat and provides a sharper flavor than the flesh. Slice the plum into wedges for breakfast, salads, or smoothies. Locate the indentation the runs down the length of the fruit; this is where the pit is. Make a cut parallel to the indentation on either side and set aside the flesh.

How long does homemade plum jam last? ›

Homemade fruit preserves can last for up to year or even longer if it is unopened and stored in a cool, dry place, such as a pantry or kitchen cupboard. However the flavour and texture of your jam will start to deteriorate after around 6 months, even if you keep them tightly sealed.

What are the best plums for jam? ›

What can I add to jam to thicken it? ›

For every 4 cups of jam that needs to be remade, whisk together 1/4 cup sugar and 1 tablespoon powdered pectin. Pour the jam into a low, wide pan and add the sugar and pectin combo. Stir until the sugar and pectin has dissolved.

How do you firm up runny jam? ›

For each quart of jam or jelly to be fixed, mix 1/4 cup sugar, 1/4 cup water or white grape juice, 2 tablespoons bottled lemon juice, and 4 teaspoons powdered pectin in a large pot. So, if you made a batch of jam and have 10 eight-ounce jars that didn't set, that would be an average batch (10 cups or 2.5 quarts).

How do you thicken jam without cornstarch or pectin? ›

If you simply take fruit and cook it with some sugar to sweeten it a little, it will get thick enough to turn into jam by the naturally occurring pectin in the fruit and the process of reduction. Reduction occurs when we simmer the fruit, and the liquid turns to steam and evaporates, which thickens the jam.
