Today’s post and recipes are a tribute to two of my favorite pizza joints, Brooklyn’s L&B Spumoni Gardens and Boston’s Galleria Umberto. While both specialize in what we collectively consider Sicilian pizza—meaning square-cut slices, baked in a pan, with a thick, close-textured crumb—neither actually originates from Sicily.

In fact, as I only just discovered, the founders of both restaurants hail from the province of Avellino, Italy, in the Campania region. (Galleria Umberto is named after a famous domed indoor shopping gallery in Naples, Campania’s capital.)
