It arrived there around 1914, introduced by a German planter who noticed the Guatemalan highlands had conditions matching Kerala. The country now exports most of its production — primarily to Saudi Arabia and the UAE for flavoring coffee. Guatemalan cooking uses very little of it. The world\u0026rsquo;s largest cardamom producer grows it almost entirely for someone else\u0026rsquo;s morning routine.\nMeet the plant Elettaria cardamomum grows 2–5 metres tall, takes 2–3 years before producing its first pods, and needs partial shade. It evolved under forest canopy in the Western Ghats of southern India; commercial operations in Guatemala\u0026rsquo;s highlands recreate those conditions with shade trees. It does not compromise on this.\nThe pods …","latinName":"Elettaria cardamomum","section":"browse","summary":"Guatemala produces about a third of the world\u0026rsquo;s cardamom.

It is your brain being told it is hot when it is not.\nThe receptor that capsaicin activates — TRPV1 — is your body\u0026rsquo;s heat detector. It normally fires when temperature exceeds approximately 43°C. Capsaicin binds to it and triggers the same signal without any temperature change. Your mouth reports that something is burning. Nothing is burning. The burning is accurate, in the sense that your heat detector is correctly reporting that it has been activated. It is inaccurate in the sense that there is no heat.

It is cassia — a different species, from a different country, with a different chemical profile. They taste similar. The labels do not tend to specify which one you have.\nThe distinction matters more in some places than others. The European Union sets limits on coumarin — a compound present in high concentrations in cassia and in very low concentrations in Ceylon cinnamon — because of concern about liver toxicity at high doses.

Not in India. Not in China. Not anywhere else on earth. For roughly two thousand years, every clove in the world came from Ternate, Tidore, Bacan, Makian, and Moti — a few dots of land in the Maluku archipelago. The Dutch, when they controlled the trade, destroyed clove trees on any island not under their authority and killed anyone who tried to grow them elsewhere. This seemed to them a reasonable approach to market control.\nMeet the plant Syzygium aromaticum is a medium-sized tropical tree, 8–12 metres tall, in the Myrtaceae family — the same family as eucalyptus and guava.
