Step 1

Add the raspberries, sugar, lemon juice and water to a pot, stir and bring to the boil. Allow it to boil for about 5 minutes, stirring often to stop it from scorching.

Step 2

Reduce the heat to low and let it simmer and bubble for 10 minutes. It will thicken further as it cools.

Step 3

Serve warm or allow to cool and store in a sterilised jar in the fridge for up to 5 days (or freeze for up to 2 months).
