Instructions: The beauty of this wartime pie from South London is that it is unbelievably easy and foolproof, provides a delicious meal from whatever is in the cupboard and can be used for either a main course or pudding.

Method: Preheat oven to Gas Mark 5, 375F, 190C. In a large bowl beat together the eggs, milk, flour, baking powder, salt and margarine. Stir in the chosen filling to make either a sweet or savoury pie. Pour the mixture into a lightly greased 10-inch pie plate and bake in a preheated oven for 35-40 minutes until set.
