The fruit of the nutmeg tree produces two edible spices - the nutmeg nut and the outer covering, mace. A whole nutmeg can be stored for years and when grated fresh ensures the strongest flavor (sweet and warm), while pre-ground is more convenient. Nutmeg is traditionally used in baking, but also adds flavor to cheese sauces, pasta fillings, spinach, and fish.
Spice Fun Fact: Nutmeg is first harvested 7-9 years after planting and is from the center seeds of the nutmeg fruit. The trees reach their maximum production after 20 years.
