US National Chocolate day
<p>In the markets of the Aztec capital Tenochtitlan, a rabbit cost ten cacao beans, a turkey hen a hundred, and a labourer’s daily wage could be reckoned in the same small, wrinkled seeds. Chocolate was money before it was ever a sweet, and the bitter, frothy drink the beans produced was reserved for priests, warriors and the emperor Montezuma, who is said to have taken it from golden cups. That a substance once counted out as currency now sits beside supermarket tills as an impulse buy is one of the longer journeys in the history of food, and 28 October — US National Chocolate Day — is an invitation to follow it from bean to bar.</p>

<p>For most of its recorded history, chocolate was something you drank rather than something you ate. The Maya and the Aztec ground roasted cacao into a paste, mixed it with water, chilli and maize, and whisked it into a foam they prized above the liquid itself. The Latin name botanists gave the tree, <em>Theobroma cacao</em>, captures the reverence: it means “food of the gods”. Crucially, this drink was bitter and unsweetened — the sugary version that conquered Europe was a later, foreign invention.</p>
<p>When the Spanish conquistador Hernán Cortés encountered the drink in Mexico in the early sixteenth century, he carried cacao beans and the equipment to prepare them back to Spain. There, cooks added cane sugar and warm spices such as cinnamon and vanilla, turning a sharp ceremonial brew into a sweet luxury for the aristocracy. For more than a century Spain guarded the recipe closely before the fashion spread to the French and English courts, where chocolate houses became as fashionable as coffee houses.</p>
<h2 id="the-century-that-made-the-modern-bar">The century that made the modern bar</h2>
<p>The leap from drink to solid bar happened, and can be dated, in the nineteenth century. In 1828 the Dutch chemist Coenraad Johannes van Houten patented a hydraulic press that squeezed much of the fat — cocoa butter — out of roasted beans, leaving a cake that could be ground into the fine, soluble powder we still call cocoa. His process, often paired with treating the powder with alkaline salts to mellow it, gave makers two ingredients they could now control separately: powder and butter.</p>
<p>That separation was the key that unlocked the bar. In 1847 the English firm J. S. Fry & Sons, in Bristol, combined cocoa powder, sugar and melted cocoa butter into a paste smooth enough to pour into a mould and set firm — widely credited as the first true eating chocolate bar. The result was still dark and rather coarse. The next breakthroughs came from Switzerland: in 1875 Daniel Peter, working with his neighbour Henri Nestlé and Nestlé’s condensed milk, succeeded in adding milk to chocolate, producing the first milk chocolate bar after years of trying to stop the water in milk from spoiling the mixture. Soon after, Rodolphe Lindt’s invention of <em>conching</em> — a prolonged stirring that smooths texture and drives off harsh notes — gave chocolate the melting fineness modern eaters take for granted. Within a single century, a courtly drink had become an industrial confection.</p>

<p>National Chocolate Day is one of several American food days that crowd the late-October calendar, and its date is no accident: 28 October sits three days before Halloween, the single biggest confectionery event in the United States, when chocolate sales reach their annual peak. The day is unofficial and its precise origin is not well documented — no founding committee or proclamation can be reliably cited — so it is more honest to treat it as a marketing-friendly fixture that grew up alongside the autumn sweet-buying season than to attach it to an inventor it does not have.</p>
<p>What the day does usefully is hold a mirror to a vast industry. Cacao grows only within roughly twenty degrees of the equator, and the bulk of the world’s supply now comes from West Africa, with Côte d’Ivoire and Ghana together producing well over half. The people who grow the beans rarely taste the finished bars, and the gap between a farmer’s income and a chocolatier’s shelf price has made cocoa a focus for fair-trade campaigns and for scrutiny of child labour and deforestation. A day nominally about pleasure is also, quietly, a day about supply chains. The same questions of provenance and craft animate a good deal of home baking, too, from a tray of <a href="/specialdate/us-national-chocolate-covered-cherry-day/">chocolate-covered cherries</a> to the simplest bar of <a href="/specialdate/us-national-milk-chocolate-day/">milk chocolate</a> melted for a fondue.</p>
<h2 id="how-it-is-marked">How it is marked</h2>
<p>There is no ritual to National Chocolate Day beyond the obvious, but the obvious takes many forms. Confectioners and chains run promotions and limited editions; bean-to-bar makers, the small craft producers who roast and grind their own beans, use it to introduce single-origin tablets and tasting flights. The serious tasters treat chocolate rather as oenophiles treat wine, comparing bars by their percentage of cocoa and by the region the beans came from: a Madagascan bar can taste of red fruit and citrus, a Ghanaian one of fudge and roasted nuts, an Ecuadorean one of flowers. The flavour differences are real and come from the variety of the tree, the soil, and above all the fermentation of the beans in the days after harvest.</p>
<h2 id="a-spectrum-of-styles">A spectrum of styles</h2>
<p>Chocolate’s adaptability is most visible in how differently it is treated across cultures. The Swiss and the Belgians built reputations on filled pralines and ganache truffles; Mexico kept faith with chocolate’s savoury roots, folding it into <em>mole</em> sauces and spicing its hot chocolate with chilli and cinnamon much as the Aztecs once did. Italy gave the world <em>gianduja</em>, the hazelnut-and-chocolate paste that became the ancestor of the modern spread. Britain’s contribution runs to the moulded countline bar and the chocolate biscuit, while the United States developed its own distinctive milk chocolate, slightly tangy from the way its milk is processed — a taste Americans find nostalgic and many Europeans find baffling. A treat as simple as <a href="/specialdate/us-national-chocolate-with-almonds-day/">chocolate with almonds</a> carries a different meaning on either side of the Atlantic.</p>
<h2 id="the-medicine-the-scandal-and-the-brand-names">The medicine, the scandal and the brand names</h2>
<p>Chocolate’s modern story is also a story of family firms, many of them founded by people who saw the drink as a moral as well as a commercial project. In Britain, several of the great chocolate dynasties — Fry of Bristol, Cadbury of Birmingham, Rowntree of York — were run by Quaker families, who were barred by their faith from many professions and from the universities, and who saw in cocoa a wholesome alternative to alcohol at a time of widespread concern about gin and beer. The Cadbury brothers built a model village, Bournville, around their factory in the 1890s, with decent housing and gardens for workers, an unusually paternalistic experiment for the age. Their devotion to “pure” cocoa was partly commercial: much Victorian cocoa was bulked out with starch, flour and even brick dust, and selling an unadulterated product was a selling point.</p>
<p>For most of its early European life chocolate was also regarded as a medicine or a tonic, prescribed by physicians for everything from low spirits to digestive complaints. That reputation has had an oddly modern afterlife. Cocoa is genuinely rich in compounds called flavanols, and chocolate contains small amounts of theobromine and caffeine, mild stimulants from the same plant family as the names suggest — though the quantities of sugar and fat in most bars mean the health halo is easily oversold. The same theobromine that gives chocolate its faint lift is, incidentally, toxic to dogs, which cannot break it down as quickly as humans can, which is why a box of chocolates is a genuine danger to a pet.</p>
<h2 id="fun-facts">Fun facts</h2>
<ul>
<li>White chocolate is, technically, not chocolate at all: it contains cocoa butter, sugar and milk but no cocoa solids, which is why it is pale and lacks chocolate’s characteristic dark colour and bitterness.</li>
<li>The Aztecs used cacao beans as money, and where there is money there is forgery — counterfeiters made fake beans out of clay and shaped them to pass for the real thing.</li>
<li>The clean <em>snap</em> of a good dark bar is a sign of correctly tempered cocoa butter, which can crystallise in six different forms; only one of them gives that glossy surface and crisp break, and it must be coaxed out by careful warming and cooling.</li>
<li>Switzerland leads the world in chocolate eaten per person, getting through several kilograms a head each year — a national habit built on inventions, milk chocolate and conching, that are barely 150 years old.</li>
<li>The melting point of cocoa butter sits just below human body temperature, which is precisely why chocolate melts on the tongue rather than in the hand, and why it feels so unlike any other sweet.</li>
</ul>
<h2 id="a-closing-reflection">A closing reflection</h2>
<p>There is a quiet lesson in the fact that chocolate was money before it was a treat. Value, it turns out, is not fixed in a thing but assigned to it: the same bean that bought a turkey in a Tenochtitlan market now sells for pennies in powdered form, while a tablet of single-origin chocolate with a named farm on its wrapper commands a premium the Aztecs would have found absurd. What changed was not the cacao but the story we tell about it. Eating a square on 28 October is a small pleasure; noticing how strange its long passage from currency to candy really is, is a slightly larger one.</p>
