Ceylon vs. Cassia Cinnamon: The Spice That's Not Created Equal

When you reach for that jar of cinnamon in your spice rack, you might be surprised to learn that not all cinnamon is created equal. In fact, there are two main types of cinnamon: Ceylon (Sri Lankan) and Cassia. Understanding the differences between these two varieties can have significant implications for your health and culinary experiences.

How to Tell Ceylon and Cassia Apart

The easiest way to identify true cinnamon is by looking at the stick itself. Ceylon cinnamon rolls into soft, multi-layered quills — thin, papery bark that curls from both sides like a cigar, easy to crumble between your fingers. Cassia is a single thick roll of hard, dark bark that curls from one side only, and takes real force to break. If your cinnamon stick snaps rather than crumbles, it's almost certainly cassia.

Ground cinnamon is harder to tell apart by sight alone — this is where sourcing and labeling matter most, since most "cinnamon" sold pre-ground in supermarkets is cassia unless explicitly labeled Ceylon or Sri Lankan.

Ceylon Cinnamon: The True Cinnamon

Ceylon (Sri Lankan) cinnamon, often referred to as "true cinnamon," is primarily grown in Sri Lanka. This variety is prized for its delicate flavor, lighter color, and distinctive shape. But beyond its culinary appeal, Ceylon cinnamon offers numerous health benefits that make it a superior choice.

Flavor and Cooking Differences

Beyond safety, the two taste genuinely different. Ceylon cinnamon is delicate, warm, and slightly sweet, with subtle citrus and floral notes — it works well in dishes where you want cinnamon's warmth without it overpowering other flavors: custards, delicate baking, tea, and coffee. Cassia is sharper, more pungent, and holds up better in bold, heavily spiced dishes like mulled wine, curries, or gingerbread, which is part of why it became the default in North American baking.

Neither is "better" for flavor alone — but if you're using cinnamon daily (in coffee, oatmeal, or smoothies), Ceylon's milder profile combined with its coumarin safety makes it the clear choice for regular use.

Cassia Cinnamon: The Common Variety

Cassia cinnamon is the more common variety found in most supermarkets, particularly in North America. While it shares some similarities with Ceylon cinnamon, there are crucial differences that set it apart.

Why Cassia Cinnamon Can Be Problematic

The main concern with Cassia cinnamon is its high coumarin content. Coumarin is a plant compound that can be harmful when consumed in large amounts.

1. Liver Damage Risk: Consuming too much Cassia cinnamon can potentially lead to liver damage due to its high coumarin content.
2. Blood Thinning Interference: High levels of coumarin in Cassia cinnamon can interfere with blood-thinning medications.
3. Allergic Reactions: Some individuals may experience allergic reactions or gastrointestinal symptoms from consuming Cassia cinnamon.

The Coumarin Comparison

The difference in coumarin content between Ceylon and Cassia cinnamon is striking:

• Cassia cinnamon contains approximately 1% coumarin.
• Ceylon cinnamon contains only 0.004% coumarin, which is 250 times less than Cassia.

To put this into perspective, consuming just 1-2 teaspoons of Cassia cinnamon could potentially exceed the daily safe limit for coumarin intake.

Source: The European Food Safety Authority (EFSA) has set a tolerable daily intake of 0.1mg of coumarin per kilogram of body weight — for a 70kg adult, that's about 7mg per day.

Frequently Asked Questions

Is Ceylon cinnamon better than cassia?

For regular or daily use, yes — Ceylon's coumarin content is roughly 250 times lower, making it the safer choice, and many find its flavor more refined for everyday cooking and baking.

How much cassia cinnamon is safe to eat?

Health authorities generally recommend keeping coumarin intake low; consuming just 1-2 teaspoons of cassia cinnamon can approach or exceed daily safe coumarin limits for some adults, especially with regular use.

Can I substitute Ceylon for cassia in recipes?

Yes, 1:1 — Ceylon's flavor is milder, so some bakers use slightly more to match cassia's intensity, but it's a direct swap.

Is all "cinnamon" sold in stores cassia?

In the US, most pre-ground supermarket cinnamon is cassia unless specifically labeled "Ceylon," "Sri Lankan," or "true cinnamon."

Making the Right Choice

Given the significant differences between Ceylon and Cassia cinnamon, it's clear that Ceylon is the safer and healthier option, especially if you consume cinnamon regularly or in large amounts. While both varieties can be enjoyed in moderation, those who use cinnamon for its health benefits or as a supplement should opt for Ceylon cinnamon to avoid the potential risks associated with high coumarin intake In conclusion, when it comes to cinnamon, choosing Ceylon over Cassia is a simple way to enhance both the flavor of your food and the benefits to your health. Next time you're shopping for cinnamon, look for "Ceylon", "Sri Lankan" or "true cinnamon" on the label to ensure you're getting the best this aromatic spice has to offer.
