ELI5: Why does salt bring out favors in any dish?
gpt
In a high school chemistry class, you'll see that saltwater is actually capable of conducting electricity. Na gives an electron to Cl and becomes positive, while Cl becomes negative. And this facilitates the electron movement and in turn, electricity. In a microscopic level, 'tasting' food just depends on tiny electric interactions. The salt helps the 'taste' from the food connect to your tongue more easily and it is dependent on it.

Another analogy: Salt is one of the most essential components our body needs to function. Therefore, our brain makes it look tasty so we consume it more. Same reason fat is more tasty, because it is more important.
