12. Soy Sauce
Unopened soy sauce can last forever thanks to its high salt content and fermentation process. Even after opening, it stays good for years if stored in the fridge. It might darken slightly over time, but that doesn’t mean it’s spoiled. Soy sauce is a staple in many kitchens, used for marinades, dipping sauces, and stir-fries. Its bold, salty flavor goes a long way, and a little bit lasts forever. For best results, choose traditionally brewed soy sauce—it tends to have fewer additives and a more reliable shelf life.
