How to tell if frozen polenta is bad
Freezer burn
Dry, greyish-white patches. Safe, but trim them off.
Ice crystals
Heavy ice inside the pack means it has thawed and refrozen.
Smell
Off smell after thawing — discard.
Package
Torn packaging lets air in and speeds quality loss.

Best-by and sell-by

Past the date
Frozen polenta past its best-by date is usually safe if stored well; check smell, look and taste before using.
How to keep frozen polenta fresh longer
- Keep your freezer at 0°F (-18°C) or colder.
- Do not let it thaw and refreeze on the way home; shop for frozen food last.
