NUTMEG
Nutmeg is the seed of the tree, roughly round-shaped and about 20 to 30 mm (0.8 to 1.2 in) long and 15 to 18 mm (0.6 to 0.7 in) wide, and weighing between 5 and 10 g (0.2 and 0.4 oz) dried, while mace is the dried “lacy” reddish covering or aril of the seed. The first harvest of nutmeg trees takes place 7–9 years after planting, and the trees reach full production after twenty years. Nutmeg is usually used in powdered form. This is the only tropical fruit that is the source of two different spices, obtained from different parts of the plant. Several other commercial products are also produced from the trees, including essential oils, extracted oleresins, and nutmeg butter.
Nutmeg and mace have similar sensory qualities, with nutmeg having a slightly sweeter and mace a more delicate flavour. Mace is often preferred in light dishes for the bright orange, saffron-like hue it imparts. Nutmeg is used for flavouring many dishes, usually in ground or grated form, and is best grated fresh in a nutmeg grater.
