The clam and mussel soups that are specialties of Naples and the nearby coastlines inspired this recipe. I’ve added shrimp for more meatiness and dried crushed red pepper flakes simply because I like it spicy, but they’re optional. Whatever you do, be sure to serve this with plenty of crusty bread; the broth is phenomenal to sop up.
Cooks' Note
The trick to this dish is to be careful not to overcook the shellfish—otherwise, it will become rubbery.
