One of the delights in eating in Romagna (and I hazard to guess all over Italy) is the “misto.”
The mix.
Where I come from, eating fish you usually get one thing. Your appetizer is one thing–a tartar, half a dozen oysters, a bowl of mussels. And your main course is usually one thing–fillet of whitefish, fillets of perch, a chunk of salmon or tuna or swordfish, some crab legs or a lobster tail. Want to taste something besides what’s on your plate? Poach a bite from your wife’s when she’s not looking.
