The menu at Medusa, the Sicilian restaurant that opened in Midtown in January, begins with sfincione. In Sicily, sfincione is a common street food, the spongy bread topped with bright, acidic tomatoes, a blend of anchovies and cheese and crunchy breadcrumbs, handed off everywhere in Palermo from the side of the road to bakeries and cafes. At Medusa, the bread is delivered as a small, puffy round pie cut into quarters.
