Mace is the outside tissue that partially covers the nutmeg seed. The fragrance is similar to nutmeg but stronger and more refreshing. It is used in a few curries, Massaman included.
Mace is available whole or ground. I prefer the whole mace because it retains its fragrance better than the ground mace.
Mace can be pricey, but I found the best price and quality at Indian markets.
