Mace is the net-like membrane surrounding the shell of the nutmeg. It is used in pickling, stews, and baked goods. Mace has a spicy nutmeg aroma and an attractive reddish-orange color. Mace works especially well with milk dishes like custards and cream sauces. It contributes to flavoring light-colored cakes and pastries, especially donuts. It can enhance clear and creamed soups and casseroles, chicken pies and sauces. Adding some to mashed potatoes or sweet potatoes creates a more interesting side dish.
