What is Fish Sauce?
Fish sauce is a fermented liquid condiment made from fish or krill that has been salted and aged for months or even years. This process results in a pungent, salty, and slightly sweet flavor that enhances the taste of many dishes.

- Salt Content: The salt content in fish sauce acts as a preservative, extending its shelf life. Higher salt concentrations generally lead to longer shelf lives.
- Packaging: The type of packaging can also impact the shelf life. Fish sauce stored in glass bottles tends to last longer than those in plastic containers.
