Pantry

Keep opened capers tightly sealed in their original brine in the refrigerator. Ensure capers are always submerged in liquid.
Freezer

Freezing capers is not recommended as it can significantly alter their texture, making them mushy upon thawing. While safe, quality is compromised.
Signs of Spoilage
- Off-odor (sour, yeasty, or unpleasant smell)
- Mold growth on the surface or capers
- Discoloration (unusual darkening or changes in color)
- Slimy or mushy texture
- Cloudy or murky brine that was previously clear
- Bulging lid on an unopened jar (indicates gas production from spoilage)
Room Temperature Safety
The 'Danger Zone' for bacterial growth is between 40°F (4°C) and 140°F (60°C). Foods in this temperature range should be discarded after the specified time limits.
Always refrigerate opened capers promptly. Discard any capers that have been exposed to the danger zone for too long.
Safe Handling
Always use clean utensils to remove capers from the jar to prevent contamination.
Ensure the lid is tightly sealed after each use to maintain freshness and prevent spoilage.
Do not consume capers if they have been left at room temperature for more than 2 hours (1 hour if above 90°F/32°C).
