literally, ‘white’ or ‘in white’. Terms used to describe the tomato-less version of a dish that can be made with or without tomatoes. A pizza bianca, for example, is a pizza made only with cheese. Lasagne in bianco means lasagne made with béchamel sauce (and, usually, a vegetable) but not ragù. One of the most well-known of these ‘double dishes’ is pasta alle vongole, which can be made either with tomatoes or in bianco.
