For putting into broiled fish just before it is sent to table.
Work the above ingredients well together, and let them be thoroughly mixed with a wooden spoon. If this is used as a sauce, it may be poured either under or over the meat or fish it is intended to be served with.
Note: 4 tablespoonfuls of Béchamel, 2 tablespoonfuls of white stock, with 2 ounces of the above maître d'hôtel butter stirred into it, and just allowed to simmer for 1 minute, will be found an excellent hot maître d'hôtel sauce.
