Foie gras is a rich culinary preparation made from the liver of ducks or geese. Its smooth, buttery texture and concentrated, savory flavor distinguish it from ordinary liver dishes. It may be served in slices, cooked or baked, or presented on bread as an appetizer; fruit such as pear can offer a contrasting sweetness, while caviar adds a briny note. Foie gras can also accompany a main course, including filet mignon. These preparations show how the ingredient appears both on its own and as part of a composed dish.
