White rocks on the meat

Everyone around the fire wants to know why the meat is so good. He tells them he put those white rocks on it. They can't believe what a cook this guy is.

Two weeks later, the people who ate it notice that the meat with the rocks on it isn't covered in mold. You made it last longer, they tell him. He answers that he meant to do that. Hey, he's a magician.

Then comes everyone's first bite of seasoned food, and the faces. They want to know how come the animal doesn't already come this way. We're never going back, they decide. We are no longer nature. We are now humans.
