Can unopened refridgerated horseradish stored in cupboard still be used?

Unopened refrigerated horseradish can generally be stored in a cupboard, but it's best to keep it in the fridge for optimal freshness and flavor. If it has been stored in the cupboard, check the expiration date and inspect for any signs of spoilage, such as changes in color or odor. If it looks and smells normal, it should still be safe to use, but the quality may not be as good as when stored properly. Always err on the side of caution and discard if in doubt.
