There's only one way to prepare carp. Get you a cedar board and lots of butter. Coat the cedar and the carp in butter and smoke it for a 20 minutes on the grill. Every few minutes put another layer of butter on so it'll be nice and soft. When it's done, throw the carp away and eat the cedar board.
The truth is, I've never tried either of those. But I do know good food is totally subjective. Maybe you'll like em and maybe you won't.
