Mace spice is a dried, outer aril, enveloping firmly around the nutmeg kernel. Nutmeg kernel and mace arils indeed are two separate spice products of the same nutmeg fruit. However, spice-mace has characteristically composed a higher concentration of certain essential oils and features a refined yet more intense aroma than nutmeg. For the same reasons, it commands a higher price and special place in the kitchen spice box.
