Mortadella di Campostosto is hand-formed into small, ovular salamis, while Mortadella di Prato looks more like mortadella di Bologna with a long, wide sausage. Given its shape Mortadella di Prato might be confused with mortadella di Bologna, but it has a stronger flavor incorporating the Florentine liquor alchermes and spices like vanilla, cinnamon, clove, nutmeg, and coriander.
