Buying Guide: Freezing Without Containers
Keep these points in mind before you buy.
Glass and silicone alternatives
Glass containers and silicone bags or trays replace many plastic uses. Glass reheats well; silicone saves freezer space.
Freezer tips
Cool food first, leave about half an inch of headspace for liquids to expand, and press out air. Flat, stackable shapes freeze and thaw faster.
Freeze flat, then stand up
Lay bags flat on a tray to freeze, then file them upright like books. Pop silicone blocks out and bag them to free the tray.
Label every container
Write the dish and date on each container. Removable labels peel off in the wash; freezer labels stay stuck in the cold.
Space-Saving Freezer Tips
Fit more in less space:
- Freeze bags flat on a tray.
- File frozen bags upright.
- Pop out cubes and bag them.
- Label every bag and block.
