In a mixing bowl, combine the egg whites, caster sugar, cornflour and lemon juice. Whisk the egg whites with an electric mixer until you have a firm, smooth meringue. Fill the Silikomart half-sphere moulds and bake at 100°C for 2 hours.
In a small bowl, mix the caster sugar and NH pectin.
In a saucepan, heat the 80g of blueberries for a few minutes. Add the sugar and pectin mixture and continue cooking for 2 minutes, stirring constantly. Remove from the heat and add a little red food colouring, as the blueberries lose their colour during cooking. Stir. Set aside to cool slightly until ready to assemble.
