Since getting back to Rome after a long stint abroad, I have made no fewer than six trips to the two Rosciolis for pizza bianca. I live half-way between these Roman institutions, and I am never very far from Pietro’s (Via Buonarotti) or Marco’s (Via dei Chiavari) place. These two forni, originally owned and operated by cousins, turn out two totally different incarnations of pizza bianca. Visit either shop Monday through Saturday 7:30am-8pm for comparison.
