Salt, sugar, and pure vanilla extract are examples of condiments that never expire due to their self-preserving properties. Salt is a mineral that doesn’t support microbial growth, while sugar acts as a preservative by absorbing moisture that bacteria need to survive. Pure vanilla extract has a high alcohol content, which inhibits bacteria growth, allowing it to maintain its quality and flavor over time. However, for optimal taste and quality, it’s advisable to use them within a few years.
