Interesting personal anecdote on salt.

After our marriage, my wife's mother shared her precious cookbook with her and asked her to copy/translate it. My wife did so and she used that as the basis of her cooking since.

There was one important component of the recipes that my mother in law had neglected to add since it was second nature to her.

"Add salt to taste."

I was always confounded whenever I tasted the food that my wife made from one of those recipes and when I tasted the exact same food when my mother in law made it.

It was only a while later that we found out what the cause of the inconsistency was.
