What You Need To Know About Freezing Food at home
Cool foods before you freeze them. Freezing food when hot will only increase the temperature of the freezer and could cause other foods to start defrosting.
It's a wrap. Make sure you wrap foods properly or put them in sealed containers, otherwise your food can get freezer-burn.
Stay fresh. You get out what you put in as freezing certainly won't improve the quality of your food. Don't freeze old food because you don't want to waste it; the point of freezing is to keep food at its prime.
In an emergency... If there has been a power cut or you think the freezer has been turned off at some point, don't open the door. Foods should remain frozen in the freezer for about 24 hours, leaving you time to get to the bottom of the problem.
