Defrosting in the fridge

When you have a frozen food you need to cook (say, a turkey), and you know you will cook it on a certain date, defrost it in the fridge. Be sure, however, to put the turkey on something in case the plastic wrapping has come apart or torn! (that way, turkey juice doesn't get all over the place in the fridge).

Anyhow, it'll save you energy because you won't be heating up something frozen to room temperature. Instead, your turkey will slowly defrost to fridge temperature and keep the fridge cool as well! Instant energy savings.
