Lampredotto is a popular street food in Florence that is not for the faint of heart. This traditional dish is made from the fourth stomach of a cow, which is slow-cooked in a flavorful broth until tender. The cooked lampredotto is then thinly sliced and served on a crusty roll, often with a generous drizzle of green sauce made from parsley, garlic, and anchovies. While it may sound unusual, lampredotto is a beloved dish in Florence and is a must-try for adventurous eaters looking to experience the local cuisine.
