The wafer paper is a sheet of unleavened bread. Its composition must be strictly observed: water, wheat flour, no salt, sugar or fat. This dough is sold in 50 x 60-cm (20 x 24-inch) sheets. The sheets are very fragile and must be handled carefully. They are called Ostia or " Torrone paper," the latter meaning "nougat" in Italian. They are found in Italian grocery stores or at France Decor in Montreal.
