shielding the food with reflective foil, which reduces it Basic Methods of Heating Foods Pure examples of the three different forms of heat transfer are seldom found in everyday life All hot utensils radiate heat to some degree, and cooks usually work with combinations of solid containers that conduct and fluids that circulate As simple an operation as heating a pan of water on the stove involves radiation and conduction from an electrical element (radiation and convection from a gas flame), conduction through the pan, and convection in the water Still, one kind of heat transfer usually predominates in a given cooking technique and, together with the cooking medium, has a distinctive influence on foods The spectrum of electromagnetic radiation We use both microwave and infrared radiation to cook our foods (The scale employs a standard scientific abbreviation for large numbers; 10 5means a followed by zeroes, or 100,000.) Grilling and Broiling: Infrared Radiation Grilling and broiling are the modern, controlled versions of the oldest culinary technique, roasting over an open fire or glowing coals In grilling, the heat source is below the food; in broiling, above Though air convection contributes some heat, especially as the distance between heat source and food is increased, broiling is largely a matter of infrared radiation The heat sources used in .. .The spectrum of electromagnetic radiation We use both microwave and infrared radiation to cook our foods (The scale employs a standard scientific abbreviation for large numbers;...
