Churning cream causes a milk fat phase inversion
Vigorous shaking transforms an oil in water emulsion into a water in fat emulsion
Heavy cream is an oil-in-water emulsion where tiny fat globules float in liquid whey. Churning cream agitates the fat globule membranes until they rupture, allowing the fat molecules to stick together. Eventually, liquid water droplets become trapped inside a continuous network of solid milk fat, resulting in butter.

- Is this really a food fact?
- Yes. It sits on the Food shelf, one of 1,090 sourced facts grouped into space, animals, the human body, history, science and more. Category pages collect every fact in the same field.
