The culinary philosophy at MAST' in Boston is rooted in a rigorous adherence to Neapolitan tradition and the mastery of the wood-burning oven. Chef-owner Salvatore Del Rosa treats pizza as a form of edible art, utilizing a 48-hour fermented dough that achieves a characteristic chewy texture and a blistered, charred crust. The O'Mast pizza is a signature example, featuring imported prosciutto, creamy ricotta, and San Marzano tomatoes in a perfect ratio of salt and sweetness. Beyond the oven, the kitchen excels in slow-cooked techniques, such as the paccheri alla Genovese, where baby back ribs are braised to the melting point in a rich onion and Chianti reduction. The aroma of toasted flour and simmering ragout fills the two-tiered space, creating an inviting atmosphere. Each plate is a testament to Southern Italian heritage, delivered with a focus on technical integrity and the soulful expression of beautifully sourced ingredients.
