Chilli Pepper
Capsicum spp.
🌍Origin
Central and South America. — c. 6000 BCE
🌱Domestication
The chilli is not a single domesticated plant but a whole genus, Capsicum, brought into cultivation many times over by many peoples across the breadth of the Americas, and its extraordinary diversity is the direct record of that repeated, independent domestication. The wild ancestors of the genus arose in the highlands of what is now Bolivia and the surrounding lowlands of South America, small-fruited, bird-dispersed plants whose pungent berries spread across South and Central America long before any human cultivated them. Five species were eventually domesticated, each in a different region and from a different wild stock, and it is this multiplicity, rather than any single founding event, that gives the chilli its bewildering range of form, colour, and heat. The most consequential of these domestications produced Capsicum annuum, the species that today encompasses the great majority of the world's cultivated chillies and sweet peppers alike. It was taken into cultivation in central and southern Mexico no later than 6000 BCE, and possibly considerably earlier: desiccated seeds and pod fragments recovered from the dry caves of the Tehuacán Valley in Puebla and from sites in Tamaulipas demonstrate that Mesoamerican peoples were growing and selecting the plant by that date, amongst the earliest of all American crops. From this single species, through millennia of patient selection, came the dried ancho (the ripened poblano), the smoked chipotle (the dried, smoked jalapeño), the fruity mulato, the searing chile de árbol, the deep guajillo, and the long vocabulary of named Mexican chillies that no other cuisine has matched. Quite separately, the civilisations of South America domesticated their own species from their own wild ancestors. Capsicum chinense, the species of the habanero and the Scotch bonnet, with its rising, aromatic, floral heat, was brought into cultivation in the Amazonian lowlands and carried northward into the Caribbean. Capsicum baccatum, the ají amarillo family that gives Peruvian cooking its golden colour and fruity warmth, was domesticated in the Andean valleys and coastal oases of Peru. Capsicum pubescens, the thick-walled, black-seeded rocoto, was selected in the high Andes at altitudes no other chilli could tolerate, and Capsicum frutescens spread as a semi-domesticated bird pepper across the lowland tropics. By the time of European contact, the peoples of Mesoamerica and the Andes between them had developed hundreds of distinct cultivars, each chosen for a particular flavour, heat, colour, and use, a breeding inheritance of more than ten thousand years that the rest of the world would receive, all at once, after 1492.
⛵Global Voyage
The diffusion of the chilli out of the Americas, beginning with the return of Columbus in 1493, is one of the swiftest and most complete migrations of any food plant in the whole of history. Where the potato, the tomato, and maize took generations to overcome suspicion and become European staples, the chilli was adopted across Africa, Asia, and the warmer parts of Europe within a single century, and in many regions it so thoroughly displaced the native sources of heat that it now seems indigenous. Columbus himself carried the first pods back to Spain from the Caribbean, where he had met the aromatic Capsicum chinense of the Taíno and named it 'pepper' by analogy with the black pepper of the Indies he had been sent to find; the misnomer has clung to the plant in nearly every European language ever since. The primary engine of the chilli's spread was not Spain but Portugal. The Portuguese maritime empire of the sixteenth century, the most geographically extensive trading network in the world, ran from Lisbon south along the West African coast, around the Cape of Good Hope, and on to Goa, Malacca, Macau, and Japan, and the chilli travelled these routes along the very sea lanes that had carried black pepper for centuries. The irony was considerable, for the chilli offered heat far cheaper and easier to grow than the spice it partly replaced, and lands that had once priced pepper in gold took up the chilli with practical enthusiasm. Portuguese ships planted it on the Guinea coast, where West African cooks who already prized the heat of grains of paradise embraced the Scotch bonnet so completely that it became the defining chilli of the region; carried it to Goa, where it entered the vindaloo and spread inland across India within a century, displacing long pepper; and brought it to Malacca, Sumatra, and the Siamese port of Ayutthaya, where it transformed the sambal and the curry paste of Southeast Asia. A second, wholly distinct route ran across the Pacific. The Manila Galleon, the annual Spanish service that linked Acapulco in New Spain to Manila from 1565, carried the chilli westward directly from Mexico into the Philippines and onward into the coastal provinces of southern China, so that Sichuan and the Fujian coast received the plant from two directions at nearly the same moment, the Portuguese stream moving inland from the south coast and the Spanish stream arriving by way of the Pacific. There it met the indigenous Sichuan pepper to create the numbing, burning málà flavour that now defines the region's cooking. A third route was Ottoman: from the Iberian Mediterranean and through Egypt the chilli entered the Ottoman world, where it became the Aleppo pepper of the Levant and the Anatolian table, and travelled north with Ottoman soldiers and administrators into the Balkans and Hungary, where two centuries of selection turned it into paprika. By way of these three great networks, Portuguese, Spanish, and Ottoman, a clutch of American plants reached the kitchens of Africa, Asia, and Europe in the span of a hundred years, and from Korea's gochujang to Ethiopia's berbere to Hungary's goulash the chilli was absorbed so deeply that it became inseparable from the cuisines that received it.
🍽Modern Culinary Role
The chilli is consumed today by more human beings than any other spice or flavouring, with an estimated 80 per cent of the world's population eating some form of it daily, and it is grown across every warm and temperate region on earth, with India, China, and Mexico amongst the largest producers. Its work in the kitchen falls into three broad registers. As a fresh ingredient it supplies heat, aroma, and bright flavour to Mexican salsas, Thai and Vietnamese salads, Indonesian raw sambals, and the relishes of East Africa. As a dried, ground, or smoked spice it becomes Hungarian paprika, Spanish pimentón, Aleppo pepper, Indian chilli powder, and Korean gochugaru, each a regional product as distinct from the others as one wine region is from another. And as a fermented or preserved paste it underpins whole cuisines: Korean gochujang, North African harissa, Chinese doubanjiang, Indonesian and Malaysian sambal, and the pepper sauces of West Africa. The heat itself is the work of a single family of compounds, the capsaicinoids, of which capsaicin is the most abundant; they bind to the same receptors that register physical heat and abrasion, so that the mouth is fooled into feeling a burn where there is no actual injury. The body answers this false alarm with a flood of endorphins, and it is this paradox, a pain that the brain rewards with pleasure, that has made the chilli the most compelling and the most addictive of all the world's seasonings. The heat is now measured on the Scoville scale, and competitive breeding has driven cultivated varieties to extremes their wild ancestors never approached. No plant carried by the Columbian Exchange has been more completely absorbed into the cooking of the wider world than the chilli. Where the potato and the tomato took centuries to win acceptance, the chilli was embraced with total commitment within a generation of its arrival in every region it reached, until the cuisines of Sichuan, Korea, Thailand, India, Ethiopia, Hungary, and West Africa became, in the modern imagination, unthinkable without it, despite the plant having been unknown to all of them before 1500. It is the rare ingredient that travelled the entire globe and was naturalised everywhere as though it had always belonged.
