Famous especially in Florence, where people queue up for steaming hot trippa alla fiorentina (the cow’s second or ‘honeycombed’ stomach, stewed in onions and tomatoes) in a bun. Or they may just order lampredotto.
trippette can mean the tripe of lamb or another small animal—or it can be fish guts, specifically the swim bladder of dried or salt cod, or other fish. Stewed with tomatoes, this was once a popular cucina povera dish in Liguria and the south.
trippa alla parmigiana: slow cooked tripe with vegetables, showered in Parmesan cheese
trippa alla romana: tripe in tomato sauce, flavoured with mint and topped with pecorino cheese. Add some hot peppers, and you have what in the Abruzzo is called trippa alla paesana.
