(Eggs, chicken, or veal)
Use the double pan with water. Make a white sauce by putting in the chafing-dish one tablespoonful of butter; let it bubble, then stir in one tablespoonful of flour; let it cook a few minutes, but not brown; then add a cupful of milk slowly, stirring all the time until it is a little thickened. Season with pepper and salt. Lay in carefully thick slices of hard-boiled egg. As soon as they are heated, place them on slices of toast softened with hot water, and pour the thickened sauce over them. For chicken or meat, season the sauce with a few drops of onion-juice, a little chopped celery if convenient, salt, pepper, and paprica. Have the chicken in good-sized pieces, or meat in thin slices, and leave them in the sauce only long enough to become well heated; canned chicken or turkey may be used. Any kind of meat can be minced and used in this way, in which case the sauce should be made with half milk and half stock. If stock is not at hand extract of beef (one teaspoonful to a cupful of boiling water) may be substituted. With chicken or oysters, the yolk of an egg is added just before it is removed, which makes it "a la poulette."
