Halibut Crudo is a light and refreshing raw fish dish that is typically served as an appetizer. The halibut is thinly sliced and marinated in a mixture of citrus juices, olive oil, and seasonings. The acidity of the citrus juices helps to 'cook' the fish, resulting in a tender and flavorful dish. The crudo is often garnished with fresh herbs, thinly sliced vegetables, and a drizzle of extra virgin olive oil.
