  • 2kg plums, stoned and roughly chopped



    The juiciest fruit in the stone fruit family, plums come in many different varieties, some sweet…

  • 2kg white granulated sugar
  • 2 tsp ground cinnamon
  • 1 tbsp lemon juice



    Oval in shape with a pronouced bulge on one end, lemons are one of the most versatile…

  • 3 cinnamon sticks (optional)
  • knob of butter



    Butter is a dairy product made from separating whole milk or cream into fat and…


  1. Sterilise the jars and any other equipment before you start (see tip). Put a couple of saucers in the freezer, as you’ll need these for testing whether the jam is ready later (or use a sugar thermometer). Put the plums in a preserving pan and add 200ml water. Bring to a simmer, and cook for about 10 mins until the plums are tender but not falling apart. Add the sugar, ground cinnamon and lemon juice, then let the sugar dissolve slowly, without boiling. This will take about 10 mins.

  2. Increase the heat and bring the jam to a full rolling boil. After about 5 mins, spoon a little jam onto a cold saucer. Wait a few seconds, 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.

  3. Take the jam off the heat and add the cinnamon sticks (if using) and the knob of butter. The cinnamon will look pretty in the jars and the butter will disperse any scum. Let the jam cool for 15 mins, which will prevent the lumps of fruit sinking to the bottom of the jars. Ladle into hot jars, seal and leave to cool. Will keep for 1 year in a cool, dark place. Chill once opened.

I followed the recipe. It took a while for it to reach 105 on my thermometer, I had to stir it to make the temperature rise. Appears to have turned out ok and of jam consistency.

Delicious Tastes of Autumn I doubled up quantities split between two pans. My plums were ripe so I added the juice of a whole lemon overall to ensure the jam set. Turned out a treat. First time making this but it certainly won’t be my last. Yummy! (Yielded approx 30 x 200g jars.)

First Jam I have ever made with plums from my first allotment, I halved the recipe it still gave me 4 small jars and 1 large jar , I am not a natural good but even I was able to follow the recipe I went out and brought a thermometer today , I thought that it will be easier

This was a disaster, I couldn't get my jam above 100 deg, even after 40 mins of boiling. Also, this "rolling boil" only succeeded in splattering half of my kitchen with a sticky plum mess. Oh & by this time the sugar was burning!! Never again.

By the way, this is the first jam I've ever made so it might just be a rookie error...

I found a sachet of pectin and used that but the jam is disgustingly sweet and I don't get the flavour of the plums. I used beautiful Victoria plums... so it's a real waste. Is there anything I can do to reduce the sweetness?

I've basically got a saucepan of plum bits in a sea of sugar syrup. Not sure what to do with it now...

Sorry to hear this has now worked well for you. At this point, we think it's going to be hard to salvage the jam.

I followed the recipe, even used a jam thermometer when i wasnt sure the jam had set - it read 105 degrees, but my jam is runny! I put it in the sealed sterilised jars hoping that it would firm up once it was cold. No such luck. Can I re-boil the jam? Any suggestions anyone?

We're sorry to hear your jam is still runny. If you used very ripe plums, the pectin level which helps the jam to set will be lower so this may have been the problem. Under-ripe plums would be best. The lemon juice also helps the setting process. If you've left the jam in the fridge for a couple of days and it's still quite runny, you can still use it as is or you'll find it's delicious as a sauce for ice cream.

I have had this happen when making marmalade even when the jam thermometer said I was at 'jam' temperature. I decanted the runny marmalade and reboiled it but used the cold saucer/wrinkle test the second time. Was fine - I'd recommend that you do this as runny jam might ferment.
