Nutmeg has a slightly sweet flavor that goes well with many foods. It is very similar to the spice - mace, in flavor as it is the seed that lies under the husk that is ground into mace. Think of a cake doughnut, and its predominant spice flavor. Then think of eggnog, and its spice flavor. Those two foods are flavored mostly with nutmeg, and a bit of vanilla, sweetened with sugar.
Nutmeg compliments everything from vanilla ice cream, to chocolate, to beef roast. It is often used as a flavoring for pudings, cakes, quickbreads, fruit preperations such as apple pie/crisp/dumplings, peach cobbler, bannana cream pie, etc. It can be mixed with cummin, coriander, ginger, and red pepper to make curry.
As others have said, purchase some, even the pre-grated stuff you buy in the spice rack and try it. Add it to your french toast, waffle, or pancake batter. Fry some bannanas in a bit of butter with brown sugar and nutmeg.
Hope that helps.
