2 Oranges,
6oz butter,
6oz sugar,
6oz S.R flour,
3 eggs
4oz sugar,
4oz chocolate,
1oz butter
Cream, butter and sugar until soft,

Stir in zest from both oranges.
Put into a lined 1lb loaf tin.
Bake at 180 degrees C, gas mark 4 for one hour.
Leave to cool in the tin.
Make a syrup from the juice of the two oranges and 4oz sugar by simmering in a pan until sugar is dissolved.
Leave the cake in the tin, and puncture holes all over it with a cocktail stick.
