All meat, poultry, game, and fish, which have received three-fourths of their dressing in the preparatory process, and the remainder in the water-bath, as already pointed out, may, when taken out of the vessels, be heated to the proper degree in order to be instantly served at table. If, for instance, the substance taken from the bottle or jar, had not received either enough previous dressing, or enough heat from the water-bath; it is immediately put on the fire in order to supply what is deficient. Consequently, when the operator has taken due care in making his preparations, having properly seasoned and dressed them, the use to be made of them afterwards, will at all events be easy and convenient; for on the one hand they will need only to be warmed, and on the other hand, they may, if necessary, be eaten cold. Substances thus prepared and preserved, do not, as might be imagined, require to be consumed as soon as they are opened. Provisions may be used from a vessel eight or ten days after it has been uncorked,[P] care being taken only to replace the cork as soon as the necessary part of the provision has been taken out. Besides, it is easy to regulate the size of the vessels from one to twenty-five _litres_ or more, according to the rapidity of the expected consumption. [P] See the report made to the _Société d’Encouragement pour l’Industrie nationale_, by Mr. Bouriat, in the name of the Committee. Two half-bottles, one of milk, the other of whey, after remaining uncorked from twenty to thirty days, had been re-corked with little cork; nevertheless the two substances retained all their properties. § XLIII. _Jellies made of Meat and Poultry._ A well prepared and preserved jelly, carefully taken in pieces out of the jar may be used to garnish cold dishes, or it may be even dissolved in the water-bath, the vessel containing it being first uncorked; afterwards it may be poured in a dish to congeal again before it is made use of. Under an infinity of circumstances, a cook may be in want of the substances necessary to make a sauce with. But with the essences of meat, poultry, ham, &c. as well as with a provision of jelly well preserved and prepared, they may be furnished in an instant. The broth or jelly prepared and preserved as pointed out in page 46 is eaten either cold as it is found in the bottles, or diluted with more or less boiling water, in the proportions which persons of experience may judge suitable in the several instances. § XLIV. _Milk and Cream._ Cream, Milk and Whey, prepared and preserved in the manner already pointed out, are used in the same way, and for the same daily purposes, as the same articles when fresh.
