Is a part of the process, upon which the quality of the cheese in a considerable degree depends. In Cheshire, more time and attention is devoted to the perfect extraction of the whey than in almost any other district. Indeed, when it is considered that the whey contains sugar and lactic acid, which may undergo decomposition, and a quantity of rennet which may bring on fermentation, by both of which processes the flavor of the cheeses must be considerably affected, it will appear of great importance that the whey should be as completely removed from the curd as it can possibly be. To aid in effecting this, a curd-mill, for chopping it fine after the whey is _strained_ off, is in use in many of the large English dairies, and a very ingenious and effectual pneumatic cheese-press for sucking out the whey, was lately invented. But the way in which the whey is separated is not a matter of indifference, and has much influence upon the quality of the cheese. Thus, in Norfolk, according to Marshall, when the curd is fairly set, the dairy-maid bares her arm, plunges it into the curd, and with the help of her wooden ladle, breaks up minutely, and intimately mixes the curd with the whey. This she does for ten or fifteen minutes, after which the curd is allowed to subside, and the whey is drawn off. By this agitation, the whey must carry off more of the butter and the cheese must be poorer. In Cheshire and Ayrshire, the curd is cut with a knife, but is gently used and slowly pressed till it is dry enough to be chopped fine, and thus more of the oily matter is retained. On the same principle, in making the Stilton cheese, the curd is not cut or broken at all, but is pressed gently and with care till the whey gradually drains out. Thus the butter and the curd remain intermixed, and the rich cheese of Stilton is the result. Thus, while it is of importance that all the whey should be extracted from the curd, yet the quickest way may not be the best. More time and care must be bestowed in order to effect this object, the richer the cheese we wish to obtain. The quality of the milk or of the pastures, may often be blamed for the deficiencies in the richness or other qualities of cheese, which are in reality due to slight but material differences in the mode of manufacturing it. _The kind of salt_ used, is considered by many to have some effect upon the taste of the cheese. Thus the cheese of Gerome, in the Vosges, is supposed to derive a peculiar taste from the Lorena salt with which it is cured. In Holland, the efficacy of one kind of salt over another for the curing of cheese is generally acknowledged. The Mode in which the Salt is applied.
