I spent a few days in Florence about 30 years ago, and while I don't remember much, I do recall my surprise at how delicious the Tuscan fish stew was. What I found so interesting was how herbs like oregano, sage, and rosemary, which I'd only associated with meat, were also used with seafood. Also, FYI just in case any old-school Tuscans are coming over: I hear that for this to qualify as an official Italian fish stew you need use at least 5 different types of seafood, which is both insane and adorable. Serve with crusty bread.
