Expiration & Storage Tips
When does chestnuts expire?
Unopened chestnuts in their shells can last for a week at room temperature, or up to one month if refrigerated. Once the shells are opened, the raw nutmeat should be used within 2-3 days if kept at room temperature, or up to a week if refrigerated. Cooked chestnuts in or out of their shells, keep well for about three days in the refrigerator. Once frozen, chestnuts retain their quality for 9-12 months.
How do you tell if chestnuts is bad?
If chestnuts have gone bad, you'll notice a number of signs. Fresh chestnuts should feel heavy and firm, and their shells should be bright and shiny. If they feel light, rattle in their shell, or their shells are dull or mottled, they're likely past their prime. Inside, the nutmeat should be creamy white - if it's discolored or has a foul or sour smell, it's best not to consume them.
Tips for storing chestnuts to extend shelf life
• Store unopened chestnuts in a cool, dry place, away from heat and sunlight. A cellar or a pantry is ideal.
• Once you've opened the shells, it's best to refrigerate the chestnuts in an airtight container.
• You can also freeze raw, shelled chestnuts. To do this, simply seal them tightly in a freezer bag or container. Allow the chestnuts to thaw in the refrigerator before using.
• Cooked chestnuts should be refrigerated and used within three days for best flavor and texture.
