What is mace? All about nutmeg’s lesser known twin, how cooks use it and a recipe idea
From the same fruit as nutmeg, mace is harder to grate but goes similarly well in cakes and milk-based dishes. It can also be used in stews

I am not sure why mace is not as well known as its twin, nutmeg. The two spices come from the fruit of the Myristica fragrans tree – mace is the seed coating and nutmeg the seed.
But while nutmeg is quite common – which cook, after all, does not have a nutmeg in the spice cupboard for grating onto eggnog or adding to a béchamel sauce? – mace is not.
The two spices are prised together out of the fruit, and the mace, which tightly surrounds the nutmeg, is removed.
When processed, nutmeg is a hard kernel that is easy to grate. The thin, delicate piece of mace remains flexible and leathery, which makes it hard to grate – I have tried without success to use a rasp grater, a hand-cranked spice grinder and an electric grinder.
