implntraining- If someone says , I prepare cheese, for me it implies that they prepare or set a plate of cheese, we prepare a meal not cheese. Those who make cheese, it starts with milk and cream, as in a farm, they make it. Setting cheese on a plate isn't making cheese, it's already made.
goopach- of course sometimes, you can use, prepare, for a meal for exemple. In the duo sentence, maybe the person who makes cheese works in a place where they make and sell cheese. There's no context. He can prepare a plate of cheese, but not the cheese itself, he has to make it.
