When you have a steak sit in its package on a table or something like a wooden or plastic cutting board or porcelain plate, it quickly cools down the surface it’s on but that coldness doesn’t spread around. This is because all of those materials are bad at conducting heat.

A metallic tray, or any metallic surface to be clear, works much better because metals are great at transferring heat. So, as the tray cools down, it quickly picks up heat from the air around it and that heat is transferred to the steak and this continues.
