What You Need to Know
The process relies on the fat globule membrane of heavy cream, which, when sheared and exposed to air, forms a dispersed phase that traps air bubbles. Stabilizers such as gelatin, cream of tartar, or sugar adsorb to the globule surface, reducing surface tension and preventing coalescence. Temperature control keeps the fat solid enough to form a network, while whipping time dictates peak firmness and prevents butter formation.
The Science
