   <Hi, Sorry for the ignorance. But what is convection, I saw it on the pumpkin cookie post? Technically, convection is the transfer of heat via fluids. There are three common methods of heat transfer, conduction, convection and radiation. Conduction transfers heat through solids, convection transfers heat through liquids and radiation transfers heat through air/space. Here's the analogies that I use. When you put a hamburger in a skillet, you are using conduction to transfer heat directly from the heat source, through the pan and into the hamburger. When you broil a steak, you are using radiation to transfer heat from the heating element through space to the meat. When you bake a loaf of bread you are using the ambient temperature of the oven to heat the liquid dough of the bread and bake it. Your oven at home is typically described as a convection oven. Hope this helps. Pat
