Question

what is the curdling process​

Answer 1

In cookery, curdling is the breaking of an emulsion or colloid into large parts of different composition through the physico-chemical processes of flocculation, creaming, and coalescence. Curdling is intentional and desirable in making cheese and tofu; unintentional and undesirable in making sauces and custards. Curdling occurs naturally in cows' milk, if it is left open to air for a few days in a warm environment.
