Simmering animal connective tissue yields liquid gelatine

Prolonged heat converts insoluble collagen into water-soluble gelatine proteins

Simmering animal bones and connective tissue for extended hours breaks down tough collagen proteins into gelatine through hydrolysis. Gelatine dissolves into the warm broth, providing a rich velvety mouthfeel and body. When cooled to room temperature or chilled in a refrigerator, the gelatine matrix sets the liquid broth into a firm gel.
