GoKawiilAmericans already lose roughly $1,500 a year to spoiled groceries, according to a 2025 CNET survey, but the freezer isn't always the rescue it appears to be.
The freezer feels like a safe haven for anything you're not ready to use or that bulk haul of produce you bought on sale. The problem? Not everything comes back from the cold in one piece. Some foods need special handling before they're frozen, while others simply can't be saved -- emerging mealy, mushy or completely inedible.
