The bones from all joints of meat, whether roasted or boiled, make excellent stock. Beef bones are the best, but very good stock can be made from mutton and veal bones. The bones and trimmings of all kinds of poultry, game, and rabbits are also excellent, particularly for soups that require a special flavour. To make this stock successfully care must be taken to remove all pieces that may be burnt, as these give the stock an unpleasant flavour. The bones must also be chopped very small, and well covered with cold water. When the pot boils put in a teaspoonful of salt and skim well, then boil steadily for six hours or longer; strain off and remove the fat, and it is ready for use, but it is much better to let it stand till the next day before converting it into soup or gravy.
