Expiration & Storage Tips
When does horseradish expire?
Unopened jarred or pre-packaged horseradish can last for up to a year if stored in a cool, dry pantry. Just be sure to check the best-by date. Once the jar is opened, it should be kept in the fridge and can last up to 3 to 4 months. Fresh horseradish root can last in the fridge for 1-2 weeks if kept dry. When frozen, grated horseradish can last up to 6 months.
How do you tell if horseradish is bad?
Jarred horseradish that's gone off will have a funky, off smell. If you notice this, it's safest to throw it out. The product can also spoil if it develops a color change, usually it turns a darker shade of brown and loses it's pungent aroma. Fresh horseradish root, on the other hand, should be firm. If it softens and becomes slimy, it’s time to discard it.
Tips for storing horseradish to extend shelf life
• Store fresh horseradish root in the vegetable crisper of your refrigerator wrapped loosely in a plastic bag.
• For long-term storage, horseradish can be frozen. To do this, peel and grate the fresh horseradish, mix in a small amount of vinegar (to preserve it and enhance the flavor), and freeze in small portions.
• Keep opened jarred horseradish in the refrigerator to retain its freshness and pungent flavor.
• Do not leave horseradish out of the refrigerator for more than two hours after opening, as this can speed up the spoiling process.
