I ask mostly out of curiosity. Obviously, a proper cookbook would involve real ingredients and not fantasy creatures. There's such a cookbook for Skyrim and Lord of the Rings. What I am curious about is this: what challenges are there in writing a fantasy cookbook where creatures that don't exist in real life are used as the ingredients?
Having trouble following along? In 1998, a Pokemon cookbook was published online. No, it wasn't a cookbook where it shows you how to make the food shown in the show of Pokemon. It was a cookbook where the writer, K.S. Suslick, used Pokemon as the ingredients.
Now in my case, I have no interest in making a cookbook involving Pokemon... but what about a cookbook where the recipes are inspired by my own fantasy world? Obviously, in order to make the cookbook be valuable to anyone aside from as a random merch item for my story, I need to include recipes that can be made with real-world items... but what about if I get to a recipe where it calls for 8 ounces of dragon steak (for example)? This is obviously just one example, but what challenges are there for such a cookbook? Assume I'm wanting it to be sellable as its own thing, not attached to a given story, so it's just a cookbook for a fantasy world.
