Foods similar to pizza have been made since the neolithic age. Records of people adding other ingredients to bread to make it more flavorful can be found throughout ancient history.
Pizza is now a type of bread and tomato dish, often served with cheese. However, until the late nineteenth or early twentieth century, the dish was sweet, not savory, and earlier versions which were savory more resembled the flat breads now known as schiacciata.[15] Pellegrino Artusi's classic early twentieth century cookbook, La Scienza in cucina e l'Arte di mangiar bene gives three recipes for pizza, all of which are sweet.[16] However, by 1927, Ada Boni's collection of regional cooking includes a recipe using tomatoes and mozzarella.[17]
