A few days ago, I read some magazine tips about saving space in the fridge, which can get so packed during the holiday season. To keep condiments upright and to prevent mess, place them in a six-pack holder on the door. Leftover casseroles? Layer them, with cutting boards or cookie sheets between the containers. To use freezer space well, a basic desk sorter (a base with vertical dividers) can hold packages of meat, veggies and other frozen foods. That could leave space for bulkier items, like bagged ice, frozen desserts, breads, etc.
