In hot weather it is important to keep the milk, cream, and butter as cool as possible. For this purpose, those who have no ice-house, or very cool milk-room, hang their cream down a well. In winter it is needful to raise the temperature of the cream a little, while churning, but care must be taken to do it very slightly, or the butter is injured. The best way is to warm the churn, and churn in a warm room.
After the weather gets cold, the cream rises more perfectly after allowing the milk to stand say ten or eleven hours, to set it over a furnace a while till it is warmed through, but not heated hot enough to boil. Then take it back, let it stand eleven hours longer, and skim it. This secures more, and better cream.
In hot weather, set the churn into a tub of cold water, and churn steadily, as stopping puts back the process, and injures the butter. In hot weather, do not churn very fast, as it makes soft butter. When the butter has come, collect it in a wooden bowl, which is the best article to work it in, having first scalded it, and then put it in cold water till cold. Do not use the hand in working over butter, as it injures it so much that a higher price is often paid for butter made without using the hand.
A wooden spad made for the purpose is the proper article for working over butter.
As soon as the butter is put in the bowl, pour in as much of the coldest water as will allow you to work the butter, and keep adding and pouring off cold water, as you work it, until the water will run off clear. It is continuing this process until all the buttermilk is extracted, which alone will secure butter that will keep good and sweet. Water hastens the process, but butter keeps longer not to have it used.
No precise direction can be given for salting, as tastes vary so much in regard to this. It is a good way to notice the proportions which are most agreeable, and note the measure, and then measure ever after.
In salting down in firkins, use the nicest rock salt, as much depends on the nature of the salt. The firkins must be very thoroughly seasoned, and the bottom covered with salt, and the sides rubbed with it. Pack the butter in layers, with salt between. After a few days, the butter will shrink from the sides, and then the space must be filled with new and nice brine. Muslin spread under and over the layer of salt, between the layers of butter is a good plan, as it saves the butter.
It is said that butter will be preserved sweet a long time for journeys, or voyages, by working into it very thoroughly a mixture composed of one-fourth salt, one-fourth saltpetre, and two-fourths white sugar.
In large dairies, the milk is churned soon after it is taken from the cow.
The quality of butter depends very much upon the kind of cows. Those who give a great deal of milk, are usually small and thin. Every cow should have a tea-cup full of salt each week, and must be well fed. Green cornstalks and carrots, are excellent for cows. Turnips, cabbage, and parsnips spoil the milk. The waste of the kitchen, with a quart of corn meal, and as much hay as she will eat daily, is good fare. Skimmed milk for drink is good, and if it is refused, withhold water, and the cow will learn to love it. Milk three times a day, and you get much more cream; stripping must be done thoroughly, or you lose cream, and dry up the cow. Never make a cow run, as it injures the milk. Use tin vessels for milk.
