Butter of commerce is made from cream of cow’s milk. The quality depends upon the breed of cow, manner of, and care in feeding. Milk from Jersey and Guernsey cows yields the largest amount of butter.

Butter should be kept in a cool place, and well covered, otherwise it is liable to become rancid; this is due to the albuminous constituents of the milk, acting as a ferment, setting free the fatty acids. First-quality butter should be used; this does not include pat butter or fancy grades. Poor butter has not been as thoroughly worked during manufacture, consequently more casein remains; therefore it is more apt to become rancid. Fresh butter spoils quickly; salt acts as a preservative. Butter which has become rancid by too long keeping may be greatly improved by melting, heating, and quickly chilling with ice-water. The butter will rise to the top, and may be easily removed.

Where butter cannot be afforded, there are several products on the market which have the same chemical composition as butter, and are equally wholesome. Examples: Butterine and oleomargarine.
Buttermilk is liquid remaining after butter “has come.” When taken fresh, it makes a wholesome beverage.
