Butter in Ancient Times.—Two kinds of butter seem to have been known to the ancient Jews, one quite like that of the present day, except that it was boiled after churning, so that it became in that warm climate practically an oil; the other, a sort of curdled milk. The juice of the Jerusalem artichoke was mixed with the milk, when it was churned until a sort of curd was separated. The Oriental method of churning was by putting the milk into a goat-skin and swinging and shaking the bag until the butter came, as illustrated in the accompanying cut.
An article still sold as butter in Athens is made by boiling the milk of goats, allowing it to sour, and then churning in a goat-skin. The result is a thick, white, foamy substance appearing more like cream than butter.
Butter-Making.—The manufacture of good butter is dependent upon good cows and the care given them, as well as most careful treatment of the milk and cream. The milk to be used for butter making, as indeed for all purposes, should be most carefully strained through a wire strainer covered with three or four thicknesses of perfectly clean cheese cloth.
The following points given by an experienced dairyman will be found worthy of consideration by all who have to do with the manufacture of this article:—
"Milk is almost as sensitive to atmospheric changes as mercury itself. It is a question among many as to what depth milk should be set to get the most cream. It does not make so much difference as to the depth as it does the protection of the milk from acid or souring. As soon as the milk begins to sour, the cream ceases to rise.
"With a clear, dry atmosphere the cream will rise clean in the milk; but in that condition of the atmosphere which readily sours the milk, the cream will not rise clean, but seems to hang in the milk, and this even when the milk is protected by being set in water.
"The benefit of setting milk in cold water is that the water protects the milk from becoming acid until the cream has time to rise. For cream to rise readily on milk set in cold water, the atmosphere in the room should be warmer than the water. As much cream will rise on milk set in cold water in one hour as on milk not set in water in twenty-four hours. The milk should be skimmed while sweet, and the cream thoroughly stirred at each skimming.
"Cream skimmed from different milkings, if churned at the same time in one churn, should be mixed eight to ten hours before churning; then the cream will all come alike.
"The keeping qualities of butter depend principally upon two things: First, the buttermilk must be all gotten out; and secondly, the grain of the butter should be kept as perfect as possible. Butter should not be allowed to be churned after it has fairly come, and should not be gathered compactly in the churn in taking out, but the buttermilk should be drained from the butter in the churn, through a hair sieve, letting the butter remain in the churn. Then take water and turn it upon the butter with sufficient force to pass through the butter, and in sufficient quantity to rinse the buttermilk all out of the butter. With this process of washing the butter the grain is not injured or mashed, and is thus far kept perfect. And in working in the salt the ladle or roll or worker, whatever it is, should never be allowed to slip on the butter,—if it does, it will destroy the grain,—but it should go upon the butter in a pressing or rolling motion."
Test the temperature of the cream with a thermometer, and churn it at 60° in summer and 62° in winter. If the butter is soft, it may be hardened by pouring onto it while working a brine made by dissolving a pint of salt in ten quarts of water. The salt used in the butter should be carefully measured, three fourths of an ounce of salt to the pound being the usual allowance.
