Does dry fish fry mix expire?

Dry fish fry mix is a combination of spices and seasonings that is used to coat fish before frying. It typically includes ingredients like flour, cornstarch, salt, pepper, and various herbs and spices. While dry fish fry mix does not contain any perishable ingredients, it can still lose its flavor and potency over time. The spices and herbs in the mix can start to lose their aroma and flavor, and the flour and cornstarch can become stale. As a result, it's best to use dry fish fry mix within 6-12 months of purchase for the best flavor and quality.
