Cream agitated until its fat globules join into a solid mass and release buttermilk, the dairy fat a northern household could concentrate, salt and keep when milk itself would not last.

Sweet-cream butter is made by churning unsoured cream until its butterfat globules join, then draining, washing, salting and packing the butter.

Butter heated until most water leaves and the milk solids separate, giving a fat that keeps far longer than butter. Rendering applies the same heat to animal tissue to make lard and tallow.
