Sweet & Sour Braised Halibut Pairing sweet and savory is common in Sicilian cooking. Here, sherry, a fortified Spanish wine, rather than Sicily's own Marsala wine, provides sweetness. In the past, without any regulation, the quality of Sicilian Marsala was poor, so some cooks used the Spanish wine. Today Sicilian Marsala is more reliable. Use either for this stew.
