Milk turned into a curd with wine is by no means so good as that which is done with rennet-water alone. The curd and whey do not separate so completely; the curd is less firm, and the whey less clear; the latter being thick and white, instead of thin and greenish, as it ought to be. Neither is it so light and wholesome as when turned with rennet.
Rennets of the best quality can be had at all seasons in the Philadelphia market; particularly in the lower part, called the Jersey market. They are sold at twelve, eighteen, or twenty-five cents, according to their size, and will keep a year or two; but have most strength when fresh. You may prepare excellent rennets yourself at a very trifling expense, by previously bespeaking them of a veal butcher; a rennet being the stomach of a calf. Its form is a bag. As soon as you get the rennet, empty out all its contents, and wipe it very clean, inside and out; then rince it with cold water, but do not wash it much, as washing will weaken its power of turning milk into curd. When you have made it quite clean, lay the rennet in a broad pan, strew it over on both sides with plenty of fine salt; cover it, and let it rest five days. When you take it out of the pan, do not wipe or wash it, for it must be stretched and dried with the salt on. For this purpose hold it open like a bag, and slip within it a long, thick, smooth rod, bent into the form of a large loop wide at the top, and so narrow at the bottom as to meet together. Stretch the rennet tightly and smoothly over this bent rod, on which it will be double, and when you have brought the two ends of the rod together at the bottom, and tied them fast, the form will somewhat resemble that of a boy's kite. Hang it up in a dry place, and cut out a bit as you want it. A piece about two inches square will turn one quart of milk; a piece of four inches, two quarts. Having first washed off all the salt in several cold waters, and wiped the bit of rennet dry, pour on it sufficient lukewarm water to cover it well. Let it stand several hours; then pour the rennet-water into the milk you intend for the curd, and set it in a warm place. When the curd is entirely formed, set the vessel on ice.
Rennet may be used with good effect before it has quite dried.
AN EASY WAY OF MAKING BUTTER IN WINTER.—
The following will be found an excellent method of making butter in cold weather for family use. We recommend its trial. Take, in the morning, the unskimmed milk of the preceding evening, (after it has stood all night in a tin pan,) and set it over a furnace of hot coals, or in a stove; being careful not to disturb the cream that has risen to the surface. Let it remain over the fire till it simmers, and begins to bubble round the edges; but on no account let it come to a boil. Then take the pan carefully off, (without disturbing the cream) and carry it to a cool place, but not where it is cold enough to freeze. In the evening take a spoon, and loosen the cream round the sides of the pan. If very rich, it will be almost a solid cake. Slip off the sheet of cream into another and larger pan, letting as little milk go with it as possible. Cover it, and set it away. Repeat the process for several days, till you have thus collected a sufficiency of clotted cream to fill the pan. Then scald a wooden ladle, and beat the cream hard with it during ten minutes. You will then have excellent butter. Take it out of the pan, lay it on a flat dish, and with the ladle squeeze and press it hard, till all the buttermilk is entirely extracted and drained off. Then wash the butter in cold water, and work a very little salt into it. Set it away in a cool place for three hours. Then squeeze and press it again; also washing it a second time in cold water. Make it up into pats, and keep it in a cool place.
The unskimmed morning's milk, of course, may also be used for this purpose, after it has stood twelve hours. The simmering over the fire adds greatly to the quantity of cream, by throwing all the oily part of the milk to the surface; but if allowed to boil, this oleaginous matter will again descend, and mix with the rest, so as not to be separated.
This is the usual method of making winter butter in the south of England; and it is very customary in the British provinces of America. Try it.
