My recipe for Easy Plum Jam is really very simple and, as plums are high in pectin so the jam will set easily. Let me take you through this easy step by step recipe so you can enjoy this sweet treat.

Easy Plum Jam

My Grandmother’s Plum Jam

Plum Jam always reminds me of my maternal grandmother. My gran was a great jam maker, every year she made raspberry, strawberry, and blackcurrant.

However, it is my Gran’s  Plum Jam I remember best of all because she didn’t bother taking out the stones. And you had to pick them out of the jam as you ate and put them on the side of your plate!

You’ll be pleased to know that I took the stones out of my jam recipe because I would hate someone to crunch down on one and break their teeth!

What kind of plums are best for jam-making?

Bowl of plums

Plums are part of a group of stone fruits that includes greengages, mirabelles, damsons and cherry plums  All of these fruits make good jam.

You can use dessert plums to make Easy Plum Jam.  The plums you buy in markets and supermarkets are usually dessert plums.  They may simply be labelled as British Plums or Yellow Plums or you may get a variety such as Victoria.

You may be able to get cooking plums from a greengrocer or from a friend’s garden if you don’t have your own plum tree.

How to make Easy Plum Jam

You will need plums, sugar, water and lemon juice. That’s all, it really is that simple to make this delicious jam.

All quantities and full instructions can be found in the recipe card at the bottom of the page

How to make Easy Plum Jam - Plums in the pan ready to jam

Prepare the plums

Halve the plums and remove the stones, put them into a large pan, I use the base of my pressure cooker.

Soften the plums and add the sugar

The plums will soften quite quickly in the water and lemon juice then you can add the sugar. Make sure that the sugar is fully dissolved before bringing it to the boil.

What is a rolling boil?

I learned about jam-making from my Mum and my grandmother by watching them.  I think it is much easier to understand when you can see what you are aiming for.

So here is a little help with the main techniques for jam making. The video above will show you what a ”rolling boil’ looks like.

HOW DO I TEST IF MY JAM WILL SET?

THE WRINKLE TEST

When you have boiled the jam for 20 minutes you can check if it will set (firm up) once cooled.  To test for setting point you can use a jam thermometer, you can use the ‘flake’ test, but I have always used the wrinkle test.

Place some saucers in the fridge before you start making the jam.  After your jam has been at a rolling boil for the necessary time, take the pan off the heat.

Put a teaspoon of the jam onto one of the cold saucers.  Place the saucer back in the fridge and leave for 5 minutes.  Then remove the saucer and push your finger across the jam.  If it wrinkles, you can skim off the froth and pot up your jam in sterilised jars.

HOW DO I STERILISE MY JAM JARS?

I sterilise my jam jars and metal lids by thoroughly washing and rinsing them.  I then put them, still wet,  upside down onto a baking tray and place it in the oven at 150C just before I start to make the jam.

The water creates steam which helps to sterilise the jars.  I take them out of the oven and fill them with the hot jam, then put on the lids.  There are other methods but this is how I sterilise my jars.

DO I NEED TO WATER-BATH THE JAM?

No. I have never water-bathed jam and my jams, jellies, and marmalade stay in good condition for at least a year kept in a cool dry cupboard.  In other countries, this is common practice and often used for lower sugar recipes.

Easy Plum Jam in dish

I always think there is something rather magical about the way fruit and sugar transform into jam. Plum Jam has the most glorious colour

The colour may vary depending on the type of plums that you use, but somehow it always looks like glowing jewels, or am I being fanciful?

More Jam Recipes from Farmersgirl Kitchen

Bowl of blackcurrants for Blackcurrant Jam

Blackcurrant Jam is one of the easiest jams you can make. Blackcurrants are naturally high in pectin which is the agent required to make the jam set.  You don’t need to add any additional pectin or lemon juice in this recipe, just blackcurrants, water, and sugar.

Greengage and Apple Jam on spoon

Greengage and Apple Jam is simple to make and a delight to eat.  Serve the jam spread on bread, toast or scones.  Use it to fill a cake or include it in a yogurt dessert, there are so many ways to eat this jam.

Jars of Gooseberry Jam

Gooseberry Jam is a rather magical jam.  You start with green or slightly pink berries, sugar and water, and the result if a glowing amber-pink and totally delicious spread.

Rhubarb and Ginger Jam recipes

Rhubarb and Ginger Jam is one of the first jams I ever made. It’s absolutely delicious and the perfect way to preserve a glut of rhubarb in the spring and early summer. Rhubarb and Ginger Jam is really easy to make and the preserved ginger adds a fabulous kick.

Total Time 40 mins
Course jam, preserves

Servings 60 servings
Calories 68 kcal

Ingredients
 

  • 900 g dessert plums (weight without stones)
  • 4 tbsp water
  • 900 g sugar
  • 2 tbsp lemon juice
  • 1 knob butter approx 1 tsp

Instructions
 

  • Halve the fruit and remove the stones.
  • Wash your jars and place in a low oven (see notes).
  • Put into a large pan with the water and cook gently until the plums are soft but not disintegrated.
  • Add the sugar and lemon juice and stir until the sugar has dissolved.
  • Bring to the boil, and boil rapidly, (rolling boil) then remove from the heat after 5 minutes and test for set (see notes).
  • When setting point has been reached, skim off the most of the froth (scum) into a bowl (you can still eat this, it’s not dirty just frothy) then add the knob of butter which will disperse the remaining scum.
  • Let it cool for about 15 minutes so the fruit settles and doesn't sink to the bottom of the jars.
  • Ladle into sterilised jars and leave to cool before sealing.

Video

Notes

To Sterilise jars: thoroughly wash the jars, rinse in cold water, then turn upside down on a baking tray. Place in the oven and turn the heat on very low leave for about 15 minutes, remove just before filling.
To Test for Set: After about 5 mins, spoon a little jam onto a cold saucer. Place it back in the fridge for 2 minutes then push the jam with your fingertip. If it wrinkles, the jam is ready. If not, cook for a few mins more and test again, with another cold saucer. If you have a sugar thermometer, it will read 105C when ready.

    I love the freshness of home made jams, plums being one of my favourites. I take the stones out and crack them, wrap the little pieces inside in muslin and cook them with the jam – this helps with the setting as the pectin is inside the stones.

    Think I attempted plum jam once, years ago, but it didn’t set and was very runny. Tasted good though but it intimidated too much until now. Maybe I should try again!

      Oh that’s a shame. I think it depends on the plums. To be extra sure of set crack the stones from the plums and put them in a muslin bag which you boil along with the jam, that will give you extra pectin.

        Thanks, Pam. It’s always an estimate on the quantity because different plums will yield a slightly different quantity. I always sterilise more jars than I think I need and sometimes they all get filled, other times not. I hope you enjoy your jam 😊

      Hi Grahame
      I’m sorry to hear that your jam has not set. Th would suggest reboiling the jam with a tablespoon of lemon juice, test for set as before. You can also use commercial pectin e.g. Certo and use the quantity suggested on the packaging and reboil. Both of these provide extra pectin. I hope that works out for you.

    The last of the plums are just turning up in a greengrocers now in Australia. The supermarkets stopped selling them a month ago. So I am making your plum jam today .I made your Spicy Courgette and Apple chutney this week. I was a bit naughty and kept a bit in the fridge . I just ate it for lunch on some homegrown beef that was corned by our butcher and then slow roasted for 3hrs 30 mins and allowed to cool for sandwiches . Both were delicious . Thank you for your recipes

      July 23, 2020 at 6:40 pm

      Hi Erica, Good to hear you had success with the recipe. In a traditional jam the sugar content is high in order to preserve the fruit and so it will keep. If you reduce the sugar the jam won’t set without artificial pectin and would need to be stored in the fridge. If you want to try this, I’d recommend that you find a specific low sugar recipe because it’s not something I’ve tried and I don’t think my recipe would work like this. I hope that is helpful.

      The jam will keep for up to a year as long as the jars are sterilised and remain unopened. Once opened it should be eaten within a week or if kept in the fridge it will keep for 2 or 3 weeks.

    Just made my first ever attempt at making jam and so far so good!!!! Our tree has produced a glut of plums so really satisfying to find a way to use them. The jam is still a little warm so not as set as i would like but hopefully in the morning it will have set properly. Would i use jam sugar next time if there is a problem with the setting or do half jam sugar half granulated sugar?? Regards Rach

      Hi Rach, so good to hear you are making your own jam. I hope your jam has firmed up a bit now. If not you could boil it up again with the juice of half a lemon and test for set again. That does tend to make the jam darker and you have to be careful not to burn it. By all means try half jam sugar if you want but its not something I’ve ever had to do. Jam making does get easier the more you do it and get to know your wrinkle test. Also homemade jam doesn’t set solid like some bought jam but nor should it be runny. I hope that helps. Janice x

      Hi Angela and Gary, good to hear you have made my plum jam. In terms of the sugar content, the sugar is key in preserving the fruit. If you reduce the sugar, the jam will not keep outside the fridge. I am able to keep my recipe for over a year without any reduction in quality or mould growth.
      My only suggestion would be to look for a freezer jam recipe or a chia seed jam. But with 3 plum trees I’m guessing you need long term storage.
      What I try to remember is that I will only be eating one teaspoon of jam at a time on bread or toast, which is no more sweet than a biscuit or piece of cake.
      I hope that helps. I will look to see if I can develop a lower sugar sweet spread but it wouldn’t be like jam

      Thanks for your feedback, it is really appreciated.

          Hi there, yes you can freeze plums. There are various opinions about whether you should freeze them whole, remove the stones, or cook them before freezing. I would generally remove the stones and cook them before freezing. If you plan to make jam with them later, then cook without sugar and add the sugar at the jam-making stage. If you plan to use the plums for dessert them add the sugar at the cooking stage. You could try cooking some and freezing some as they are and see how you get on but they will need to be cooked when they come out of the freezer. Best of luck,
          Janice
