METHODS OF HEAT TRANSFER Conduction Heat travels through something solid solid. © PDST Home Economics

CONVECTION Heat travels with air or liquid that is moving. This sets up currents. Hot air/liquid rises. Cold air/liquid falls to take its place. Eventually the whole area is heated.

RADIATION Heat travels to food in rays in the same way that it travels to earth from the sun. Radiation occurs when food is grilled. The food does not touch the grill, but the heat cooks the food.

COOKING METHODS Using fats….. Roasting and frying Moist methods….. Boiling, poaching, stewing, casseroling, steaming, pressure cooking

Dry Methods……. Baking Grilling

MICROWAVE COOKING Electromagnetic waves cause the particles of food to vibrate. This causes heat to build up inside the food. The heat then travels through the food by conduction.
