People who are really good at something – what’s it like in your head while you’re doing it?

I’m good at cooking and have had practice with a wide array of ingredients.

Some things are just muscle memory and others there’s this sort of process of mentally “cooking a meal” in my head that I will do which will give me an idea of which methods/temperatures/flavor profiles will yield me the result I am looking for and over the years the accuracy continues to grow.
