Differences/Similarities between cinnamon and nutmeg
Try to remember where you read that. And then don't read them anymore.

If you find your nutmeg and cinnamon tasting at all similar, they've both turned to dust and should be discarded.

And next time, buy whole nutmeg - it tastes much better freshly-grated, and keeps much longer without turning into vaguely-spicy-bitter dust.
