Greek style rice pudding, rizogolo.
Boil rice with half a litre of water until rice is soft, then drain and leave to cool.
In a saucepan, add 1 litre of milk, sugar, orange rind and vanilla extract or vanilla pod.
Stir constantly over a moderate heat, without boiling, until sugar is dissolved.
Add cooked rice and cook for a further 10 to 15 minutes. Stir occasionally so that it doesn't burn at the bottom. If you are using custard powder, remove the rind and then blend with the rest of the milk.
To serve, sprinkle with cinnamon and eat hot or cold. This is not suitable to freeze, but can be made a day ahead and stored in the refrigerator.
