§ 37161 Butter Production Standards

• •It can be made from fresh or aged milk or cream.

Making butter at home by shaking cream in a jar.

If you shake cream long enough, the fat clumps together and turns into butter. This is exactly what the law says butter is—just the fat from milk or cream, with a tiny bit of other milk parts mixed in.
