My dad had a recipe for carp. He didn't particularly like carp but this was pretty much as good as it could get. You don't have the scale it or anything. Just cut 2 slits down either side of it's back to make pockets. Then find some cow manure and roll it into balls. Yes this is real, I know it sounds weird but it's the best way there is to cook it and it needs to be cow manure, but horse is also acceptable. Just don't get stupid and try human or dog shit. Insert the balls into the slits you just made. Then throw it in the oven at I think 250 degrees for 45 minutes. I can double check that cook time if anyone is planning to try this recipe. When it's done, scoop out the balls, and throw away the fish.
He said he tried smoking one once but it wouldn't stay lit.
