Begin your compote by placing the blueberries, lemon juice, and caster sugar into a small pot. Gently stir the mixture to ensure that the sugar and lemon juice coat all the berries evenly.

Turn on the heat to low or medium-low. This will allow the berries to begin releasing their juices gradually, creating a luscious syrup.

Let the mixture simmer, stirring occasionally, for about 10 to 15 minutes. The berries will soften, and you’ll notice the juices thickening into a beautiful compote.

Once the blueberries have softened and the compote has thickened to your desired consistency, remove it from the heat. Transfer the mixture into a clean jar or bowl and allow it to cool before storing it in the fridge.
