Blackberry jam recipe

At the right time of year bushes and hedges are brimming with blackberries.   You can buy them from the supermarket or even pay to pick your own, but it makes no sense when they are so abundant and easy to find. When you get them home, there are loads of ways to use up blackberries and this blackberry jam recipe is one of our favourites!

We are very lucky to have lots of blackberry picking spots in our local area, as well as in our hedge in our garden. Blackberry picking is a fun family outing in our garden and neighbourhood.

Blackberry jam recipe


  • 1kg freshly picked blackberries
  • 1kg golden caster sugar
  • 2 tablespoons freshly squeezed lemon juice
  • 1 pinch freshly ground rock salt        


  1. Wash blackberries and add to saucepan along with the lemon juice and freshly ground salt
  2. Bring the blackberry, lemon juice, salt mix to the boil and keep stirring for around 20 mins.
  3. Sterilise your jars and make sure the utensils you will use on them and the jam are also sterilised.  I chose to steam sterilise my jars and lids in a tiered steamer saucepan.  
  4. Towards the end of the 20 minutes add the sugar and mix well
  5. Carefully remove the jars from the steamer and put a funnel into the jars.  Next decant your jam into the jars
  6. Fit the lids on tightly and ‘process’ the jars in boiling water for 10 mins.          
  7. Remove the jars carefully from the saucepan and leave them to cool.
  8. Refrigerate 

I do not have proper canning jars* with fresh lids and a proper canning system for ‘processing’ the jars (i.e. ensuring the jars are entirely covered while being boiled and kept separate during the process) and so after cooling my jam needed to be kept in the fridge.  

Even if you do have all the proper equipment proceed with caution as not all recipes are safe for long term storage in jars in cupboards and I can provide no guarantees that this one is.

  1. I use the same recipe! We don't have blackberries around here but we do have wild huckleberries so I make jam every year. The last two years I actually started using honey instead of sugar and it turns out just as tasty!

    Thanks for your comment Annie, substituting sugar for honey sounds like a great idea for next time!

  3. We had a great Blackberry harvest this year, this will be a great recipe to try. It looks delicious. Hope you had a great week end and thank you so much for sharing with Full Plate Thursday.
    Come Back Soon!
