Glass containers with narrow necks or those that are not specifically labeled as freezer-safe should never be put in the freezer. These containers can easily crack or shatter due to the expansion of liquids as they freeze, leading to a potentially dangerous situation and wasted food. Opt for wide-mouth, freezer-safe glass, plastic containers, or freezer bags to avoid any mishaps.
