Derby Pudding:

Put a layer of jam into a buttered pie-dish. Cover with stale sponge-cakes cut in fingers; add more jam and more cake till dish is nearly full. Make a boiled custard with the yolks of 2 eggs, 1 pint milk, and tablespoonful sugar. Flavour with vanilla, and pour over cakes. Let this soak 1 hour. Then whip the whites of the 2 eggs, add a very little sugar and vanilla. Spread over the top of pudding. Place in a quick oven to slightly brown.
