Equipment

  • Saucepan

Ingredients

  • 400 g fresh blackberries
  • 300 g granulated sugar
  • 1 lemon juice

Instructions

  • Slice blackberries. If your blackberries are large, then slice them into halves and quarters. Place two saucers in the freezer (to be used later on).
  • Mix ingredients together. In a medium saucepan add the blackberries, sugar and lemon juice, and mix together.
  • Simmer until the sugar has dissolved. Over medium-low heat, bring the mixture to a simmer and stir continuously until the sugar has fully dissolved- can take approximately 5 to 8 minutes.
  • Bring the jam to a boil until thickened. Stirring frequently, increase heat to medium and allow the fruit to bubble for 10 to 15 minutes until the fruit starts to thicken.
  • Test if your jam has reached setting point. Remove from the heat and place a small dollop on a cold saucer. Push your finger through the dollop and if it feels gel-like and wrinkles then the jam has reached setting point. If it isn’t ready, return the pan to the heat and boil for another five minutes before testing.
  • Store. Ladle jam immediately into sterilised jars leaving 2 cm from the top and seal immediately with a screw top lid.

Notes

Step-by-Step Photos: My blog post includes helpful step-by-step photos to help guide you through making this recipe.
To store: If jars have been sterilised, store jam at room temperature in a cool, dark place away from direct sunlight. A pantry cupboard is perfect. Once the jar is opened, then refrigerate and enjoy within 3 weeks.
To freeze: When filling the jars, leave 2 cm (1-inch) head space. Once the jam has cooled, securely close it with a lid and freeze it for up to 1 year. Thaw overnight in the refrigerator.
TIP 1: Choose fresh blackberries that aren't overripe. Too soft or slightly blemished fruit can cause the jam to spoil.
TIP 2: A wider base saucepan is best. This allows the water to evaporate quicker from the fruit.
TIP 3: Use a long-handled wooden spoon. The jam does spit when bubbling, and it's piping hot!
