directly above the coals up and over the top of the burger,
melting the cheese.
Grilled burgers cook through all three forms of energy
transfer.You might notice that these three types of heat transfer
heat only onto the surface of foods. In order for food to
cook through to the center, the outer layer must transfer its
heat to the next layer, and so on, until the very center of the
food begins to warm up. Because of that, the outside of
most cooked foods will almost always be more well done
than the center (there are tricks to minimizing the gradient,
which we’ll get to in time).
Microwaves are the only other standard method of
energy transfer we commonly use in the kitchen, and they
have the unique ability to penetrate through the exterior of
