Nuts

Nutmeg is not classified as a true nut, but rather as a:
1. Seed: Nutmeg is the seed of the nutmeg tree (Myristica fragrans), native to the Banda Islands in Indonesia.
2. Drupe: More specifically, nutmeg is a type of drupe, a fruit that has a hard stone or pit in the center, surrounded by a fleshy outer layer.

The nutmeg seed is:
1. Enclosed in a fruit: The seed is enclosed in a fruit called a pericarp, which is similar to an apricot or a peach.
2. Covered in a lacy, red membrane: The seed is covered in a lacy, red membrane called an aril, which is often dried and used as a spice called mace.

So, while nutmeg is often referred to as a spice or a nut, it's actually a seed that's derived from a fruit!
