6. take off the heat, beat in the butter

7. add the eggs, put back on the heat, and stir till it bubbles

8. take off and cool a little, then spoon into the tart case

9. meringue – blend the blueberries to form a powder

10. beat the egg whites till firm, then add sugar and corn flour gradually, then blueberries

11. spoon onto the top of the filling. Bake at 200c for about 12 minutes. Cool completely
