What does "season it to taste" mean? I hear chefs like Gordon Ramsay say this and many, many others. 

When a chef has boiled potatos or bacon or spinach...

Be it my family or Betty Crocker ...
What are the "seasons" they are talking about????

[Please note] I am not asking "How much" but "What is"
Add your preferred level of salt and pepper
Seasoning usually refers to salt and black pepper, but occasionally to other flavor-enhancing ingredients in the dish such as acid (vinegar, lemon, etc.) and heat (red pepper, sriracha, etc.). &quot;To taste&quot; means to the degree you enjoy it.
