There are two main types of cinnamon: Cassia and Ceylon. Cassia is more common and has a stronger flavor, while Ceylon is milder and considered "true" or "sweet" cinnamon. Ceylon cinnamon is known for its delicate, mild taste. In contrast, Cassia cinnamon has a more powerful, spicier flavor and is the type more commonly found in most Western countries and supermarkets, so it is more common in many Western dishes.
