“That is very true, but it has the fault of not keeping long. In a few days it turns sour and uneatable. All the other cheeses would do the same, all would spoil and become sour if certain measures were not taken to prevent this. These measures consist in the use of salt, which is rubbed and sprinkled on the outside of the cheese, and sometimes even mixed with the curd itself. All cheeses, then, that are to be kept a long time receive more or less salt, while fresh cheese is not salted at all.
“Of these salted cheeses some are soft, some hard. [[319]]That of Brie, named from the district where the best is made, in the department of Seine-et-Marne, is a large and thin soft cake, made of sheep’s milk. It is salted on both sides with finely powdered salt, and is left to soak for two or three days in the salted liquid that drips from it. The salting finished, the cheeses are packed in a cask with alternate layers of straw, and are left alone for several months. Then there starts a kind of fermentation, which is the beginning of putrefaction, and which develops new qualities. The curd loses its odor and insipid taste of milk-food, to acquire the heightened flavor and strong smell of cheese; its mass becomes more oily, even partially fluid, and changes under the rind to a liquid pap of creamy appearance. This work of modification is called refining. It has gone just far enough when the liquid part under the rind is of a pleasant taste. The cheeses are then taken out of the cask and are ready for eating.
“This first example shows us that cheese acquires its peculiar qualities through an incipient deterioration. Before this putrefaction sets in the cheese is simply curd, sweetish, insipid, without pronounced odor; after this process it has the odor, the taste, in fact all that is required to make it really cheese. But the putrefaction, once started artificially, does not stop where we should like it to stop. It goes on all the time, slowly indeed if we take some precautions, and the cheese, smelling more and more, and tasting stronger and stronger, ends by becoming a mass of rottenness. All cheese, therefore, when it [[320]]gets too old, is sure at last to go bad; it spoils by continuing to excess the kind of deterioration that in the beginning gave it precisely the qualities desired.
“From its appetizing flavor and fine texture Roquefort is the king of cheeses, the prominent feature in any well-appointed dessert. Its renown extends all over the world.”
“That’s the cheese that is so strong and takes so much bread to go with it?” asked Emile.
“Yes, that is it. Its pronounced flavor and its blue streaks make it easy to recognize. It is made in a village of Aveyron called Roquefort, and is obtained from sheep’s milk only, the best of all milk on account of its richness in casein and butter.”
“Brie cheese also,” observed Louis, “is made of sheep’s milk; yet it doesn’t compare in quality with Roquefort.”
“That marked difference shows us how much the method of making it determines the quality of cheese. You have just seen what pains are taken with Brie cheese; now see how much care is given to Roquefort.
“The cakes of curd are not thin in this case, but as thick as they are wide. They are stored for months in grottoes hollowed in the heart of a rock, either by nature or by man, in the environs of the village of Roquefort. These grottoes are remarkable for the strong currents of air that circulate through them, and for the coolness of their temperature. During the summer, while the thermometer [[321]]outside marks thirty degrees,[1] it shows but five inside the cheese caves. The difference is that between the heat of an oppressive summer and the cold of a severe winter. It is in the depths of these cold caves that the cheeses acquire their peculiar qualities. The only care given them is an occasional rubbing with salt and a scraping of their surface to remove whatever moldiness may have developed. This moldiness even gets into the inside by degrees, where it forms blue veins. But that is in no way detrimental; on the contrary, the flavor of the cheese gains by the formation of this mold, which is merely another kind of rotting that adds its energies to those of the usual change undergone by cheese. Hence the makers are not content with letting nature produce these signs of moldiness: they hasten the process by mixing with the fresh curd a little powdered moldy bread. The cheese would be better if left to its own working, but this addition accelerates the result, and to-day, alas, in the making of Roquefort, as in so many other branches of industry, there is greater eagerness for quick results than for excellence.
“The cheese called Auvergne is made in the mountains of Cantal. Cows’ milk is used. When the curd has formed, the dairyman, legs and arms bare, mounts a table and tramples and compresses with feet and hands the mass of fresh cheese to squeeze out the whey. The curd is then separated, mixed with pounded salt, and pressed in large round molds [[322]]containing up to fifty kilograms. These enormous cheeses are finally left in cellars to the action of fermentation, which perfects them.
