A terrine is a type of meat or fish dish that is cooked and served in a loaf-shaped mold. It can be made with various ingredients such as game, poultry, seafood, vegetables, or fruits, and may include other components like eggs, cream, or wine. The terrine is typically seasoned with herbs, spices, and other flavorings before being baked or steamed until set. Once it has cooled, the mold is removed to reveal the dish in its loaf shape.
