This pudding is something between a cheese souffle and a Welsh Rabbit, but is much easier to concoct than either and guaranteed to please everybody. By simple arithmetic it can easily be adapted for two, four, or even 20.
Lightly toast and butter the bread. Cut it into squares or triangles and place a layer in a buttered casserole. Cover with a layer of thinly sliced cheese, dust with Parmesan and seasonings and repeat these layers; the top should be cheese, dusted with mustard and paprika. Beat the eggs well and add enough half milk and half cream, or rich milk, to make 3 cups. Add Worcestershire sauce. pour over the casserole and allow to stand for at least one hour, occasionally depressing with a wooden spoon so that the liquid covers all of the ingredients. If necessary add more whole milk. Preheat the oven to 400 degrees F for at least 10 minutes, cover the casserole with a cover or aluminum foil and place in the oven for 12 minutes. Remove the cover and bake for 25-30 minutes longer, until the casserole is puffed and browned. Serve at once with iced tea, coffee, or cold beer, with a green salad. This can be made in a roasting pan if the number of your guests so indicates.
