Mix the sugar, flour and cornflour into a paste with a small portion of the milk.
Scald the remaining milk with the Hinds Spices Cinnamon and remove it before adding the cornflour mixture.
Return the saucepan to the heat and cook for 15 minutes, stirring until thick and smooth.
Remove from heat and stir in the butter. When cool, add the egg yolks one at a time mixing well. Set aside to cool slightly.
Line a quiche tin with shortcrust pastry. Whisk the egg whites until soft peaks form and fold into the milk mixture.
Bake in a hot oven at 220°C for 10 minutes until risen, reduce the heat to 180°C and continue to bake for 30 – 40 minutes until the pastry is browned and the filling is set.
Sprinkle Hinds Spices Cinnamon over the top just before serving.
