All meats intended to be boiled and served whole at table must be put into boiling water, thus following an entirely opposite rule from those intended for soups. In the latter, the object being to extract all the juice, cold water must always be used first, and then heated with the meat in. In the former, all the juice is to be kept in; and, by putting into boiling water, the albumen of the meat hardens on the surface and makes a case or coating for the meat, which accomplishes this end. Where something between a soup and plain boiled meat is desired, as in beef bouilli, the meat is put on in cold water, which is brought to a boil very quickly, thus securing good gravy, yet not robbing the meat of all its juices. With corned or salted meats, tongue, etc., cold water must be used, and half an hour to the pound allowed. If to be eaten cold, such meats should always be allowed to cool in the water in which they were boiled; and this water, if not too salt, can be used for dried bean or pea soups.
