Anchovies marinated in vinegar are a delicious and tangy appetizer that is popular in Mediterranean cuisine. The small, oily fish are soaked in a mixture of vinegar, herbs, and spices, which infuses them with a zesty flavor. The marinating process also helps to soften the fish and remove any strong fishy taste. These marinated anchovies can be served as a standalone dish, added to salads, or used as a topping for bruschetta or crostini.
