Often said to be as old as the Palazzo Vecchio and as loved as Dante's poetry, lampredotto is Florence's favorite street food and a delicacy not found anywhere else in the world. Prepared for centuries as a quick, cheap and easy meal, lampredotto is basically the fourth stomach of a cow (the abomasum), boiled until tender in an aromatic onion, celery, and tomato broth.
This tripe-like dish is prepared as a flavorful, hearty stew that's traditionally used for panini di lampredotto - bread roll sandwiches filled with steaming hot, sliced lampredotto, topped with a spoonful of Italian salsa verde herb sauce.
