You will never get out of pot or pan anything fundamentally better than what went into it. Cooking is not alchemy; there is no magic in the pot - Martha McCulloch-Williams* †
With respect to Ms. McCulloch-Williams (Who I am fairly certain would bristle at the honorific “Ms”. Good.) cooking is most certainly alchemy.
The bringing together of base materials which, through the manipulation of four basic elements (air, fire, water and earth), are transmuted into something sublime. If all you care about is nourishment, try Soylent. If you want to create a spagyric or an elixir of life, you need the magic that is cookery.
