In the making of large and medium cheeses the presser is used, while space left empty by the pressure is again filled with curd, so that the mould is always full, and the cheese gets its requisite size. In the smaller or four-pound cheeses, the hands alone are used for this pressing into the mould. The mould, now pressed full, is put into a tub, properly washed in whey, and cleansed of all remaining fat. By the washing and smoothing the cheese must get a glossy and smooth rind. After this is done, the cheese is again taken out of the mould, wrapped in a clean linen cloth, put in again, and covered over and brought under the press, that it may become harder and firmer, and that the whey may run off.
In hot weather the cheese is left under the press five hours, from nine in the morning till two in the afternoon; but, if it is cool, it must stand longer. There are several different objects in view in deciding the continuance of the pressure. Many think two or three hours sufficient, whilst others press five hours. Cheese designed for export is pressed longer, or twelve hours.
It takes from three to four hours, usually, from the pouring in of the milk to the bringing of the cheese under the press; but it can be done in two or two and a half hours without injuring the cheese.
After the first pressing is finished, the cheese is put into another mould, rounder than the first, and with only one hole in the bottom, to lie in the salt. In many places a long trough is used, in which several such moulds are placed to be salted at the same time; and for this either dry salt or pickle (brine, or salt in solution) is used. The pickle is most commonly used, and is thought best. When one side of the cheese has laid some hours in the brine, it is turned, and the other side is also salted. After a while it is salted or turned in the brine but once a day. Small four-pound cheeses remain nine days in hot weather, and in cold ten or twelve days, in the salt; medium ones of ten to twelve pounds must lie at least three weeks. In very hot weather they are often salted twice a day. The moulds with the salted cheese are placed, several together, into the cheese-vat where the brine is, or on a salting-tray where the brine is collected in a tub beneath. After being finally salted, they are washed perfectly clean with water or warm whey. Many put their cheeses from the brine immediately in a kettle of hot whey for some minutes, and wash them in it. All unevenness or roughness got in pressing in the mould is now scraped off with a knife.
After the washing, the cheeses are again perfectly dried, and laid on the shelves in the cheese-room, where they are daily turned, and remain from two to four, and even five weeks. The cheese is now salable; but before it is packed or delivered it is laid for some hours to soak in pure, cold spring or well water, the smallest for three hours, the medium four, and the largest five hours. The cheese is then well cleaned with the cheese-brush, laid on the shelf in the store-room, and turned a week or more, daily. But, in order to give them a fine yellow color, in damp weather, especially, the poorer ones are, by many dairymen, laid a good ways apart, and sprinkled or washed daily with new beer. When the cheese is to be sold, it is properly washed still again in hot whey, and rubbed with a woolen cloth a day before sending to market, with hot or cold linseed-oil, by which the outside of the cheese gets a fine glow; but it must be rubbed till no fat or oil is to be felt.
The Red Color of Edam Cheese.
—After the dairyman has sold his cheese to the merchant, it is colored by him quite red. It will not be uninteresting to many readers to know some of the details of this peculiar color.
Edam cheese is colored with what is called tournesol, which is extracted from a plant (Croton tinctorium). This is an annual, which grows wild in France, in great abundance, in the vicinity of Montpelier, in Languedoc; and around Aix, in Provence, large commons are sown with it. The seed is sown in March and April. From a white and straight tap root, it sends up a stalk something like six inches high, which divides into many branches. The leaves have very long stems, of a pale green color. The flower-stalks spring up from between the branches, and bear flowers in fan-shaped clusters. The vegetation of the plant continues four months.
The preparation of the tournesol is as follows: The plants are collected late in summer, the roots thrown away, and the other parts taken to a mill, where they are ground, and the juice pressed out. Into this juice the rags of old hempen cloth are dipped till they are soaked full, when they are hung up to dry in the sun. When they are dry they are laid on a tray over a tub filled with urine, in which carbonate of lime has been dissolved, so that the edges hang over the rim of the tub on which they rest. The vapor from the solution of lime must penetrate the rags, and this gives them a violet color, when they are taken off and dried again, to be replaced till they are fully colored.
The tournesol rags have become an article of commerce, for which France receives annually from Holland from 100,000 to 200,000 guilders (from $38,000 to $76,000).
