The Grande Imposture: How to Find (and Buy) True Ceylon Cinnamon

by ceylonimp 6 min read 0 comments

Here is something the global spice trade would rather you didn’t know: the cinnamon in your kitchen cupboard is, in all probability, not cinnamon.

Or rather it is a cinnamon, but almost certainly not the one. Not Ceylon cinnamon. Not Cinnamomum verum, the true cinnamon, native to Sri Lanka and entirely distinct in flavour, texture, chemistry, and character from the cassia bark that has quietly colonised most of the world’s spice shelves under the same name.

This is not a minor technicality. It is a distinction that matters for your cooking, for your health, and for your understanding of what a truly extraordinary spice can be. Let us correct it, once and thoroughly.

Two Cinnamons, Two Stories

Deux cannelles, une seule vérité.

Ceylon Cinnamon (Cinnamomum verum) also known as “true cinnamon” or “soft cinnamon” is native to Sri Lanka. It has been harvested here for over two thousand years, traded by Arab merchants, coveted by Portuguese colonisers, and prized by spice markets from London to Lyon for the delicacy of its flavour. The bark is thin, papery, and rolled in multiple layers like a fine cigar. The taste is complex: sweet, warm, floral, with gentle citrus notes. There is no harshness, no bitterness. Just elegance.

Cassia (Cinnamomum cassia or C. aromaticum) is a different species entirely native primarily to China and Vietnam. It is cheaper to grow, faster to harvest, and considerably more robust in both flavour and bark thickness. It is also, depending on the quantity consumed, a matter of some health concern for reasons we shall come to.

They are not interchangeable. They are not the same thing. One is simply wearing the other’s name.

The Roll Test: The Most Reliable Way to Tell Them Apart

Le test décisif en un coup d’oeil.

If you have cinnamon sticks as opposed to powder the distinction is immediately visible.

Ceylon cinnamon quills are rolled in multiple thin layers, like a scroll of parchment. The bark is delicate, almost papery, and the quill feels light. When you look at it from the end, you can see many fine, tightly wound layers all the way through like a Swiss roll, if you will.

Cassia sticks are formed from a single thick layer of bark, rolled once and dried. They are dense, hard, and difficult to break or grind. Looking at the end, you see only one or two thick layers more like a log than a scroll.

This single observation will tell you everything you need to know. If your stick snaps cleanly and feels hard as wood, it is cassia. If it crumbles and layers apart when broken, it is true cinnamon.

The Colour Test

La couleur ne ment pas.

Ceylon cinnamon is a warm, light tan almost a soft beige with a golden undertone. It is never deeply brown.

Cassia ranges from dark reddish-brown to a deep, richer brown considerably darker than true cinnamon. Ground cassia powder tends to be a deeper, more saturated colour than genuine Ceylon cinnamon powder.

This is not conclusive on its own colour can vary with drying and processing but it is a useful secondary indicator.

The Taste & Aroma Distinction

Le goût ultime arbitre de qualité.

Smell a piece of each.

Ceylon cinnamon is delicate, floral, and slightly sweet with citrus undertones and a warmth that arrives gently and stays politely. It is a background perfume, a suggestion of warmth rather than a demand for attention.

Cassia is intense, sharply sweet, and almost medicinal. It is the flavour of most commercial cinnamon biscuits, American “cinnamon” flavouring, and cinnamon-scented candles which is precisely why so many people encounter it as the definitive version. It is not subtle. It does not do subtle.

In cooking, this distinction is significant. Ceylon cinnamon integrates beautifully into both sweet and savoury dishes without dominating them. Cassia can overwhelm a recipe with its intensity, and its higher essential oil content makes restraint advisable.

The Health Distinction: Coumarin

L’argument de santé et pourquoi il est sérieux.

Here is the matter that elevates this question beyond mere gustatory preference.

Cassia contains significantly elevated levels of coumarin a naturally occurring compound that, in high doses, is associated with liver toxicity and may interfere with blood thinning medication. The European Food Safety Authority has set an established tolerable daily intake for coumarin, and regular consumption of cassia particularly in the quantities used by enthusiastic bakers and golden latte devotees can exceed this threshold.

Ceylon cinnamon contains coumarin at approximately 250 times lower concentration than cassia. For most practical purposes, it is considered safe at any reasonable culinary quantity.

This does not mean a pinch of cassia will harm you. But it does mean that those using cinnamon specifically for its health benefits blood sugar regulation, anti-inflammatory effect, metabolic support should ensure they are using the real thing. The health literature on cinnamon’s benefits is largely based on Ceylon cinnamon. Extrapolating those benefits to cassia is, at best, optimistic.

Where to Buy Ceylon Cinnamon (And What to Look For)

Où trouver la vraie cannelle sans se faire avoir.

Ask the question. Any reputable supplier should be able to tell you the species. If they cannot specify Cinnamomum verum or “Ceylon cinnamon,” assume it is cassia.

Buy from origin-specific brands. The closer to Sri Lanka, the more likely the authenticity though proximity alone is no guarantee. Look for suppliers who know their growers, visit estates, and can explain their sourcing with specificity.

Inspect the quills. Use the roll test. No reputable supplier of Ceylon cinnamon will be offended by the question.

Prefer whole quills over powder. Cinnamon powder is far easier to adulterate and impossible to verify visually. Grind your own from whole quills you have examined.

At Ceywoods, our cinnamon is harvested from Sri Lankan estates we know personally true Cinnamomum verum, peeled, rolled, and dried by skilled artisans. Every quill can be inspected, broken, tasted, and smelled with confidence. This is what the word “authentic” ought to mean.
