Is it safe to use expired tempura mix?

Using expired tempura mix is generally not recommended, as the quality and safety of the ingredients may deteriorate over time. While it might not be harmful to consume if it has been stored properly and shows no signs of spoilage, such as off smells or discoloration, the texture and flavor may be compromised. Always check for any specific expiration or best-by dates, and when in doubt, it’s best to err on the side of caution and discard it.
