Baked mushrooms

Peel and stem large mushrooms. Line a deep bake-dish with thin slices of toast, each of which has been dipped for an instant in seasoned beef stock. Fill the dish with layers of mushrooms, sprinkling each layer with salt, paprika, and bits of butter. When the dish is full, pour over all a gill of stock, and bake, covered, for twenty minutes. Uncover and cook for five minutes before sending to the table.
