Unless for brown hash, or corned beef hash, potato is not used. Chop the meat to a fine mince. Put a tablespoonful of butter into a frying-pan with one slice of onion; remove the onion when cooked, and add one tablespoonful of flour, and let it brown, thus making a brown roux, if the hash is to be made of beef or mutton. Do not let it brown if it is to be used for veal or chicken hash. To the brown roux add slowly a cupful of stock or hot water; then a cupful and a half of minced meat; season with salt and pepper; stir until well incorporated, and serve at once on toast. To a white roux add slowly a cupful of milk; then add one and a half cupfuls of veal or chicken chopped fine; season with salt and pepper. Cut toast into large circles with a biscuit-cutter. Spread them with a thick layer of mince, and on this place a poached egg, neatly trimmed to the same size as the toast. It can be cut with the same cutter, or it may be poached in a muffin-ring.
Put a dash of pepper on the center of yolk. Garnish with parsley. This makes a very presentable breakfast or luncheon dish.
