Webb22 juli 2024 · Boiling is a moist method of cooking in which foods are immersed in a liquid that is either at or brought to the boiling point. This liquid may be water stock, milk or court bouillon. Heat Transfer Heat is conducted through the equipment surfaces to the liquid in contact with them. The liquid transfers this heat to the food by convection currents. WebbUnder some circumstances, the solid phase can transition directly to the gas phase without going through a liquid phase, and a gas can directly become a solid.
