Baccalà Mantecato is a traditional Venetian dish made from salted codfish. The fish is soaked in water to remove the salt, then boiled until tender. It is then mashed and whipped with olive oil, garlic, and parsley until it becomes a creamy and flavorful spread. Baccalà Mantecato is typically served on crostini or as a filling for sandwiches. It is a popular appetizer in Venice and is often enjoyed with a glass of local white wine.
