Cinnamon — Choosing the Right Kind

Lesson B of Module 4: The Spice Apothecary — Part of our 12 Months of Discovery series. Concept Cinnamon is one of the oldest traded spices in the world. Egyptian, Roman, and Chinese healers used it for metabolic and digestive complaints long before modern medicine had a framework to explain why it worked. Today, research suggests that cinnamon may improve insulin sensitivity and help moderate post-meal blood sugar responses—making it one of the most practically useful spices for everyday cooking. There is, however, a detail that most cinnamon enthusiasts don't know: the cinnamon sitting in your cupboard is almost certainly not the cinnamon used in traditional medicine. And for daily use, that distinction matters. Mechanism There are two main types of cinnamon sold commercially, and they are meaningfully different. Cassia cinnamon (Cinnamomum cassia or Cinnamomum aromaticum) is the variety found in virtually every grocery store in North America. It has a bold, sharp flavour and a deep reddish-brown colour. It is also significantly higher in coumarin—a naturally occurring compound that, at high daily intake, may affect liver health. For occasional baking, this is not a concern. For people adding cinnamon to their oatmeal, smoothie, and tea every single day, the cumulative intake is worth considering. Ceylon cinnamon (Cinnamomum verum), often labelled as "true cinnamon," contains far lower levels of coumarin—typically less than 1% of the amount found in Cassia. It has a milder, more complex, slightly floral flavour that works beautifully in both sweet and savoury applications. It is also the variety most closely associated with the blood sugar research, as its cinnamaldehyde content and overall compound profile differ from Cassia in ways that appear metabolically relevant. The practical takeaway: if cinnamon is something you use occasionally, Cassia is fine. If it is part of your daily routine—which, after this module, it may well be—Ceylon is the more considered choice. Kitchen Application Making the switch to Ceylon is simple. The main adjustment is expectation: Ceylon is subtler than Cassia, with less of the sharp heat and more of a warm, layered sweetness. Once you adjust, most people find they prefer it. Here is where it works best: Morning porridge and overnight oats. Ceylon's gentle flavour integrates beautifully into oats, teff porridge, or millet without overpowering other ingredients. Smoothies and tonics. A quarter teaspoon of Ceylon in a morning smoothie adds warmth and metabolic support without the sharpness of Cassia. Spiced teas and golden milk. Ceylon pairs exceptionally well with cardamom, ginger, and turmeric in warming drinks. Savoury dishes. Cinnamon has a long history in savoury cooking—Moroccan tagines, Persian rice dishes, Indian biryanis. Ceylon's milder profile makes it easier to use in these contexts without tipping into sweetness. Baked goods. Ceylon works well in muffins, quick breads, and pancakes. For very bold, spiced bakes where you want that sharp Cassia punch—a classic cinnamon roll, for instance—Cassia remains the better choice. How to Source It Ceylon cinnamon is increasingly available, but you need to look for it specifically. What to check: Look for the label "Ceylon" or "true cinnamon" or the botanical name Cinnamomum verum. Ceylon sticks are visually distinct: they are thinner, more tightly rolled, and have a tan rather than reddish-brown colour. The layers are delicate and crumble easily, unlike the thick, hard quills of Cassia. Specialty grocers, South Asian food markets, and online spice retailers are the most reliable sources. Most mainstream grocery store cinnamon—even premium brands—is Cassia unless explicitly labelled otherwise. The Grounded Kitchen RuleIf cinnamon is part of your daily routine, make it Ceylon. Save Cassia for occasional baking.
