1 litre milk
2 eggs and 2 egg yolks
80g custard powder
150g unsalted butter
800g poached Agen prunes soaked in Armagnac
Preheat the oven to 150ºC. Heat the milk. Beat the eggs sugar and custard powder. Pour over a third of the hot milk and combine well. Pour in the pan containing the rest of the milk and bring to the boil stirring throughout. Simmer for five minutes.
