Melktert (milk tart, South African style)

This is the original South African version of melktert but I used a store bought crust instead of doing that from scratch.

Ingredients:

1 cup milk
2 tbsp. butter, room temp.
4 tbsp. corn flour
6 tbsp sugar
2 eggs, yolks separated
1 tsp cinnamon powder
1 cinnamon stick
1 ready made pie crust

Method:
Roll out the pie crust over the tart pan, line the tart pan with it and trim the edges as needed.
Preheat the oven to 375°C.

Heat the milk in a pan with the cinnamon stick.
In a bowl, cream the butter sugar and corn flour. Now add the heated milk in a thin stream and keep whisking until combined. Now transfer back to pan and heat for a few minutes until it thickens and forms a custard. Pour this through a sieve into a bowl to cool slightly.

Beat the egg whites until stiff. Add the egg yolks to the thickened milk mixture and whisk.
Fold the egg whites. Pour this custard into the prepared tart pan and bake in the oven for 18-20 minutes or until cooked and firm. Remove and sprinkle with cinnamon. Chill in refrigerator when cooled.

Cut into wedges and serve.
