answer very well for the basis of many gravies, unless these are wanted very rich indeed. By the addition of various store sauces, thickening and flavouring, the stocks here referred to may be converted into very good gravies. It should be borne in mind, however, that the goodness and strength of spices, wines, flavourings, &c., evaporate, and that they lose a great deal of their fragrance, if added to the gravy a long time before they are wanted. If this point is attended to, a saving of one half the quantity of these ingredients will be effected, as, with long boiling, the flavour almost entirely passes away. The shank-bones of mutton, previously well soaked, will be found a great assistance in enriching gravies; a kidney or melt, beef skirt, trimmings of meat, &c. &c., answer very well when only a small quantity is wanted, and, as we have before observed, a good gravy need not necessarily be so very expensive; for economically-prepared dishes are oftentimes found as savoury and wholesome as dearer ones. The cook should also remember that the fragrance of gravies should not be overpowered by too much spice, or any strong essences, and that they should always be warmed in a _bain marie_, after they are flavoured, or else in a jar or jug placed in a saucepan full of boiling water. The remains of roast-meat gravy should always be saved; as, when no meat is at hand, a very nice gravy in haste may be made from it, and when added to hashes, ragoûts, &c., is a great improvement. [Illustration: GRAVY-KETTLE.] GRAVY-KETTLE.--This is a utensil which will not be found in every kitchen; but it is a useful one where it is necessary to keep gravies hot for the purpose of pouring over various dishes as they are cooking. It is made of copper, and should, consequently, be heated over the hot plate, if there be one, or a charcoal stove. The price at which it can be purchased is set down by Messrs. Slack at 14s.
