Nutmeg is a warm, aromatic spice — the seed of a tropical tree — grated to powder just before use.
On a cold or creamy drink, grate it over the top rather than in. The aroma is a volatile oil: it sits on the surface and reaches the nose before the first sip. In a simmered drink it can go into the pot with the other spices. A few passes of a fine grater is the whole dose. It suits cream, aged spirits and coffee, and is the usual finish on a flip or a Brandy Alexander.
Pre-ground nutmeg
Use a little more and taste. It is the exact same spice, but it loses flavor fast in the jar, so it will not smell as fresh.
Mace
The lacy coating of the same seed. Accounts of its strength differ from mild to potent, so start with half a pinch and taste.
Allspice or cloves
Use a smaller pinch, since both are sharper.
Cinnamon
Helps out in a sweet drink, though it will taste of cinnamon rather than nutmeg.
Whole nutmegs keep for years in a sealed jar and stay potent because the oil is locked inside the seed. Ground nutmeg is finished within months. Buy whole and keep a grater beside the jar.
