I need to incorporate how it enhances food:
- Reddit. https://www.reddit.com/r/explainlikeimfive/comments/mk0w3o/eli5_how_does_salt_enhance_flavour/gtdn08m/?utm_source=share&utm_medium=ios_app&utm_name=iossmf&context=3
- The taste buds in the tongue are type of receptor called an ion gate. An ion gate is like a normal gate that can be unlocked with a key except the key is a metal ion of some kind, usually sodium or calcium.
- Salt is sodium chloride, an abundant source of sodium ions. So basically the abundance of sodium ions keeps the gate unlocked and as a result the molecules that are the flavours are detected all the time.
