As a kentucky native, no on fish soups.
It would be a heckuva specialty. Fry it, make burgers out of it, eat it out of cans, smoke it, but no on soups.
Ain't no fish soups round here. ain't no how no way. We'll take it as a kindness if you just keep your fish outta my soups.
I think that this game isn't a "Kentucky Simulator" but the world it's BASED on it. Whit the new cooking system I don't see any problem to be able to make fish soup. If the last thing you found to eat it's a fish soup, you would say that you won't eat it because you're from Kentucky and the people there doesn't eat any fish soup? It's a survival game and you have to take max profit possible of every thing that you can eat. If we get in a complex matter about it, you can do a lot of things whit just the head of the fish, a lot of different sauces for rices, salads etc.
I want to add that we are here in the forums since the very early stage of the game, we are in the "wave" and we discuss everything in there. But a lot of people doesn't and I can imagine their faces when they see that they can't do something that the other 99% of the planet does and they wouldn't understand this point. -Why the hell I can't make a tasty fish soup?
One idea for this difference of opinions can be that you can make fish soup but you won't find any as a random generated loot in the world. I think it's an acceptable end. You won't see any fish soup in your gameplay world if you don't make it and we still can make something "normal" for the rest of us.
I have to point that I don't like the fish, but where I'm from, it's very typical to do (translated to english) the Canarian Fish Soup (or something like this). I know that Canary Islands are a very small portion of people, really small, but for example, Ditoseadio, the one who made the Spanish translation of Project Zomboid it's from here.
Sorry for my bad english...
