Line some patty-pans with cheese pastry, and fill them three parts full with the following mixture: Place two ounces of finely-grated breadcrumbs in a bowl, and mix into them one raw egg and a tablespoonful of milk; then add two tablespoon-fuls of finely-grated cheese, and two teaspoonfuls of butter, one teaspoonful of made mustard, half a teaspoonful of salt, and the same of pepper. Mix very well. Place the patties in the oven and bake until a pale brown. The mixture will swell slightly in baking. Serve very hot.
