This uses a fan system to blow hot air around food. Mechanical convection uses outside forces to circulate heat and shorten cooking times, such as in a convection oven. This occurs naturally when you boil water in a pan, but you can also achieve it mechanically. An example here would be putting a pan on a gas hob and the flame heating it directly to cook the food that it contains.Ĭonvection combines heat conduction transfer with circulation, forcing molecules in the air to move from warmer to cooler areas. Your choice of cooking appliance might be an oven, stove or microwave, and these will use different forms of heat transfer.Ĭonduction is the transfer of heat through direct contact.
When you’re cooking, the heat transfer is between the cooking appliance and your items of food. This is the transfer of thermal energy between two objects.
So, to start off let’s have a think about the science behind cooking food….Ĭooking, in general, involves heat transfer. Radiant is one of the key principles to know when cooking on an Aga range cooker and is useful knowledge for those looking to perfect their range cooking skills! Aga range cookers use radiant heat and this brings a very different quality to the food you cook.
