Cassia is not cinnamon: how to tell them apart
Most of the cinnamon sold around the world is actually cassia. They are related, but they taste and behave differently, and the difference is easy to spot.
Here is a fact that surprises most cooks: the jar labeled cinnamon in a typical supermarket is usually Cassia, a related but distinct bark, not the true Ceylon cinnamon the name implies. They come from different trees, and once you know the tells, you will never mix them up again.
Look at the stick
This is the fastest test. Ceylon cinnamon quills are thin, soft, and made of many fragile layers rolled together, like a cigar; they crumble easily. Cassia is a single thick, hard curl of bark, darker and redder, tough enough that grinding it at home is a chore. If the stick is one hard scroll, it is cassia.
Taste the difference
Ceylon cinnamon is delicate, floral, and gently sweet. Cassia is the bold, hot, familiar cinnamon punch most people grew up with, the flavor of cinnamon rolls and breakfast cereal. Neither is better; they are tools for different jobs.
Which to use when
- Reach for Ceylon cinnamon where its delicacy is the point: custards, rice pudding, fine baking.
- Reach for cassia when you want bold, hot cinnamon flavor that stands up to dough and braises.
- In most everyday recipes either works; just know the stronger one is almost always cassia.
