Why is it impossible to create? Are we talking about some meal that King Richard I had (https://en.wikipedia.org/wiki/The_Forme_of_Cury is the oldest cookbook I'm aware of which covers meals Richard II would have eaten), and thus we can only guess? Are we talking about the long extinct dodo bird (I'm not sure if humans ate them), cave bear (I've seen it claimed humans hunted them to extinction, but better sources say it went extinct before humans), or something else that we can never make?

For almost everything else we can create them - just give a reasonable cook a kitchen and the ingredients and they will do it. For a picture we then have an artist do preparation to make it look good, but they should always start with the real dish.
