You should churn at least twice a week, for if the cream is allowed to stand too long, the butter will inevitably have a odd taste. Add to the cream the strippings of the milk. Butter of only two or three days gathering is the best. With four or five good cows, you may easily manage to have a churning every three days. If your dairy is on a large scale, churn every two days.

Have your churn very clean, and rinse and cool it with cold water. A barrel churn is best; though a small upright one, worked by a staff or dash, will do very well where there are but one or two cows.

Strain the cream from the crock into the churn, and put on the lid. Move the handle slowly in warm weather, as churning too fast will make the butter soft. When you find that the handle moves heavily and with great difficulty, the butter has come; that is, it has separated from the thin fluid and gathered into a lump, and it then is not necessary to churn any longer. Take it out with a wooden ladle, and put it into a small tub or pail. Squeeze and press it hard with the ladle, to get out all that remains of the milk. Add a little salt, and then squeeze and work It for a long time. If any of the milk is allowed to remain in, it will speedily turn sour and spoil the butter. Set it away in a cool place for three hours, and then work it over again. [Footnote: A marble slab or table will be found of great advantage in working and making up butter.] Wash it in cold water; weigh it; make it up into separate pounds, smoothing, and shaping it; and clap each pound on your wooden butter print, dipping the print every time in cold water. Spread a clean linen cloth on a bench in the spring-house; place the butter on it, and let it set till it becomes perfectly hard. Then wrap each pound in a separate piece of linen that has been dipped in cold water.

Pour the buttermilk into a clean crock, and place it in the spring-house, with a saucer to dip it out with. Keep the pot covered. The buttermilk will be excellent the first day; but afterwards it will become too thick and sour. Winter buttermilk is never very palatable.

Before you put away the churn, wash and scald it well; and the day that you use it again, keep it for an hour or more filled with cold water.
