From a smoke-free home, this was purchased in Portugal many years ago, but never used. Used as a decorative item only. Design: It features a clamshell design with a hinged, locking lid that seals tightly to steam food in its own juices. Material: It is crafted from hand-hammered copper, which provides superior heat distribution. Use: It is traditionally used to prepare cataplana or seafood stews and works on stovetops or in ovens. Elegant copper serving dish with a hammered finish, perfect for enhancing your dining experience. One side hinge is a tad looser than the other, but this does not affect functionality in my opinion.
