Can you use black pepper a year out of date?

Yes, you can generally use black pepper a year past its expiration date, as it doesn't spoil in the same way perishable foods do. However, its flavor and potency may diminish over time, so it might not provide the same taste impact in your dishes. It's a good idea to smell and taste it before using to ensure it still meets your standards. If it has an off smell or taste, it's best to discard it.
