Equipment: 20cm ovenproof pan or baking dish.

Preheat the oven to 170°C fan bake.

Put the blueberries and sugar in a saucepan and heat until the blueberries are thawed and juicy. Stir the lemon juice and cornflour together until smooth then stir into the berries. Simmer gently for 5 minutes until the berries and the juice are glossy and lightly thickened. Tip the fruit into the pan or dish.
