  • 900g fruit (blackberries, plums, raspberries or strawberries), prepared weight
  • 900g golden granulated sugar
  • knob of butter



    Butter is made when lactic-acid producing bacteria are added to cream and churned to make an…


  1. Put the fruit into a preserving pan or large heavy-based saucepan. For blackberries, add 50ml of water and 1½ tbsp of lemon juice; for plums (halved and stoned), use 150ml of water; for strawberries, add 3 tbsp of lemon juice (no water); and for raspberries, add nothing. Bring to the boil.

  2. Lower the heat. For blackberries, simmer for 15 minutes; for plums, simmer for 30-40 minutes; for raspberries, simmer for 2 minutes; for strawberries, simmer for 5 minutes. The fruit should be soft.

  3. Tip in the sugar, stir over a very low heat until the sugar has completely dissolved. Raise the heat, bring to a full rolling boil, then rapidly boil blackberries for 10-12 minutes, plums for 10 minutes, raspberries for 5 minutes or strawberries for 20-25 minutes - don’t stir though – until the setting point of 105C is reached.

  4. Remove from the heat, skim off any excess scum, then stir a knob of butter across the surface (this helps to dissolve any remaining scum). Leave for about 15 mins so the fruit can settle. Pour into sterilised jars, label and seal.

Perfect I'm a first timer at jam after picking too many blackberry this year however this is definitely going to become a yearly thing in our house. I've done 3 batches ready for Christmas presents. Thank you my hubby says best blackberry jam he has ever tasted.

Great recipe. Think I will be spending more and more time in the kitchen jamming, as the English summer has officially disappeared. I also found this site to purchase some lovely jars from as well. High quality, cheap and fast delivery. Happy days.

Wow, how easy and fun to do with the kids. Picked, cooked and eaten....Big smiles and excitement that they made something from scratch. This is such a 'Yummy' jam as described from my 5yr old kids. Off out to pick some more blackberries to freeze for another day cheers x ps lime also works (didn't have any lemons!)

A brilliant method and recipe. I'm hopeless but I triumphed here. I am now trying it with less sugar (I'm a diabetic) ill let you know how it goes.

If using blackberries, I would definitely use jam sugar (i.e. with added pectin), otherwise it's very likely to turn out runny.

Howdy, I have just made a Blackberry jam although... It's not quite jam! It's fairly runny, Can I fix this?

Hi, yes you can. Buy some pectin (the stuff that makes jam set), either powder or liquid. Re-boil you jam and add the pectin as per its instructions. Test for set by either a jam thermometer, or by the cold plate in the freezer method (put a drop of the jam onto a plate which has been cooled in the freezer for a while, wait for a few seconds for it to cool, then push it with your finger. If it wrinkles, it's ready). Pot up into freshly sterillised jars. Blackberries and strawberries are naturally low in pectin, which is why they need it added to help the jam set. Commercial pectin is made from apples I believe.

I have made the Plum and also Blackberry using this recipe both were wonderful and I have orders for more from my neighbours and family xx perfect recipe, followed to the letter but on this times batch of Plum I am adding Vanilla essence.......I will keep you posted !!

Lovely! I made the strawberry jam but I used jam sugar and I only needed to boil it for 12 minutes before it reached setting point. This meant that it made 1.5 litres of jam. I intend to make lots more using other fruits as well.
