Step 1

Place a couple of saucers in the freezer, ready to test the setting point of the jam. Place the berries, sugar and lemon juice in a large microwave safe bowl and stir until well combined. Cook, uncovered on Medium/50% power, stirring after 2 minutes to dissolve the sugar, for 5 minutes.

Step 2

Cook uncovered on High/100% power, stirring every 3 minutes, for 16 minutes or until jam reaches setting point.

Step 3

To test for setting point, place a teaspoon of the jam mixture on a chilled saucer, place in the freezer for 1 minute. Run your finger through the jam, if the mixture wrinkles and stays separated the jam is ready.

Step 4

Pour the hot jam into clean jars, turn the jars upside down for 2 minutes, then invert and leave to cool. Label and date.
