What is Cinnamon, Really?
To understand the distinction between cinnamon and Ceylon cinnamon, you must first recognize that the spice simply labeled “cinnamon” in most stores refers to a family of trees, not a single variety. The term most commonly refers to Cassia cinnamon ($Cinnamomum extit{cassia}$), which comes primarily from China and Indonesia and is the most widely available and affordable option. In contrast, Ceylon cinnamon ($Cinnamomum extit{verum}$ or $Cinnamomum extit{zeylanicum}$) is often called “true cinnamon” and is native to Sri Lanka. While both come from the bark of evergreen trees in the Lauraceae family, their distinct origins lead to critical variations in taste, appearance, and chemical composition.
The Crucial Coumarin Difference and Health Implications
One of the most important factors for health-conscious consumers is the presence of coumarin, a natural flavoring substance that can cause liver damage in high doses.
-
Cassia Cinnamon: Contains significantly higher levels of coumarin, ranging from 0.4% to 1.2% in powder. The European Food Safety Authority (EFSA) and German Federal Institute for Risk Assessment (BfR) have established a Tolerable Daily Intake (TDI) for coumarin of 0.1 mg per kg of body weight. For a small child or a sensitive adult, regular daily consumption of Cassia can easily exceed this safe limit, making Ceylon the preferable choice for long-term or frequent use.
-
Ceylon Cinnamon: Often called “the safer cinnamon,” Ceylon contains only negligible amounts of coumarin (0.004% to 0.01%). This low level makes it safe for daily consumption, especially for those using cinnamon for its potential health benefits like blood sugar regulation or those with pre-existing liver conditions.
Flavor Profile and Culinary Uses
The flavor and aroma of each variety also differ significantly, influencing their best culinary applications.
-
Cassia Cinnamon: Known for its bold, strong, and spicy flavor profile, with a slightly bitter aftertaste. Its robust flavor stands up well to heavy spices and strong ingredients. It is the go-to cinnamon for many traditional baked goods, coffee, and hearty savory dishes.
-
Ceylon Cinnamon: Possesses a much milder, sweeter, and more complex flavor with delicate notes of citrus and flowers. Its subtle sweetness complements rather than overpowers. This makes it ideal for delicate desserts like custards, pastries, and is the traditional choice for Mexican cuisine.
Appearance and Physical Characteristics
When purchasing whole cinnamon sticks, the visual differences are clear and can help you identify the type.
-
Cassia Sticks: Are thick, dark reddish-brown, and hard. They consist of a single, thick layer of bark that curls into a rigid scroll. It is difficult to break or grind by hand.
-
Ceylon Sticks: Have a lighter, tan-brown color. They are composed of numerous thin, fragile layers of bark rolled tightly together, resembling a cigar. These are soft and easily crumble, making them easy to grind.
Ground cinnamon is much harder to distinguish visually, though Cassia tends to be a darker, more reddish-brown, while Ceylon is a lighter tan.
Comparison Table: Cassia vs. Ceylon Cinnamon
| Characteristic | Cassia Cinnamon | Ceylon Cinnamon |
|---|---|---|
| Botanical Name | Cinnamomum cassia | Cinnamomum verum or zeylanicum |
| Origin | China, Indonesia, Vietnam | Sri Lanka (formerly Ceylon) |
| Coumarin Content | High (0.4–1.2%) | Very low (0.004–0.01%) |
| Health Risk | Potential for liver damage with regular high intake | Safe for daily, long-term consumption |
| Flavor | Strong, spicy, pungent, slightly bitter | Mild, sweet, complex with floral/citrus notes |
| Appearance (Sticks) | Thick, hard, single-layer roll | Thin, multiple paper-like layers, brittle |
| Price | Affordable, common in supermarkets | More expensive, found at specialty stores |
| Best Use | Hearty baked goods, savory dishes, coffee | Delicate desserts, fine pastries, teas |
Conclusion
Understanding what is the difference between cinnamon and Ceylon cinnamon comes down to flavor preference, culinary application, and, most importantly, health considerations. The cheaper and ubiquitous Cassia cinnamon offers a robust, spicy kick but poses a health risk with regular high consumption due to its high coumarin content. The premium, delicate, and safer Ceylon cinnamon provides a mild, complex flavor profile suitable for fine cooking and daily consumption without the same liver concerns. The best practice is to know what you are buying, so you can make an informed choice that suits both your recipe and your wellness goals.
Expert Tip: Check Your Spice Rack
To determine which type of cinnamon is currently in your pantry, look at the packaging. If it simply says “cinnamon” without specifying “Ceylon” or “true cinnamon,” it is almost certainly the high-coumarin Cassia variety. Consider replacing it with properly labeled Ceylon for daily use and to be sure you are getting the health benefits without the associated risks.
