SIMPLE, STRAIGHTFORWARD AND DELICIOUS BLACKBERRY JAM RECIPE.

Calories: 44 kcal
Author: Martina Hardiman
Ingredients
  • 1.8 kg Blackberries
  • 1.5 kg Jam Sugar
  • Juice of 1 Lemon
Instructions
  1. Pop a couple of saucers into the freezer to chill.

  2. Put the blackberries, sugar and lemon juice into a preserving or large pan. Place over a low heat and simmer gently until all the sugar is dissolved. 
  3. Bring to the boil and simmer for 5 minutes. Remove from the heat. 
  4. Put a teaspoonful of jam onto a chilled saucer for 1 minute. Drag your finger lightly over the jam. If it wrinkles, it has reached setting point. If it doesn’t, boil for a couple more minutes, then turn off the heat and try again with another chilled saucer. 
  5. Skim off any excess scum, then stir in the knob of butter. This will help to dissolve any remaining scum.

  6. Leave the jam for 15 mins before ladling into sterilized jars – this allows the fruit to settle so it doesn’t sink to the bottom. 

  7. Seal and Label. 
  8. Store in a cool, dark place for at least 6 months. Refrigerate jars once opened.
Recipe Notes

 

STERILISING JARS

Wash them in hot, soapy water, then dry in an oven heated to 150C/130C fan/ gas 2 for at least 10 minutes.

Always ladle the jam into jars while the jars are still warm so they don't crack open. 

 

LABEL MAKER

I used this free Jam Labelizer for creating amazing labels. 

 

TIP: Did you know that you can use milk to stick the labels on jars? Yes, just brush a bit of milk onto a paper label and stick on. It works!
