Here is a very basic cake recipe. I can imagine it would have plenty of scope for adding to or modifying.
1lb self raising flour
6ozs butter or lard
4ozs castor sugar
2ozs currants
2ozs sultanas
2ozs raisins, stoned and chopped
2 eggs, well beaten
Rub the butter or lard into the flour then add the other ingredients also a drop of milk if required.
Put in a well greased tin and bake for one and a half hours.
