Blackpepper is native to the Malabar Coast of India,[3][4] and the Malabar pepper is extensively cultivated there and in other tropical regions. Ground, dried, and cooked peppercorns have been used since antiquity, both for flavour and as a traditional medicine. Black pepper is the world's most traded spice,[5] and is one of the most common spices added to cuisines around the world. Its spiciness is due to the chemical compound piperine, which is a different kind of spiciness from that of capsaicin characteristic of chili peppers. It is ubiquitous in the Western world as a seasoning, and is often paired with salt and available on dining tables in shakers or mills.
Black pepper is produced from the still-green, unripe drupe of the pepper plant.[2] The drupes are cooked briefly in hot water, both to clean them and to prepare them for drying.[9] The heat ruptures cell walls in the pepper, speeding the work of browning enzymes during drying.[9] The drupes dry in the sun or by machine for several days, during which the pepper skin around the seed shrinks and darkens into a thin, wrinkled black layer. Once dry, the spice is called black peppercorn. On some estates, the berries are separated from the stem by hand and then sun-dried without boiling.[2] After the peppercorns are dried, pepper spirit and oil can be extracted from the berries by crushing them.
White pepper consists solely of the seed of the ripe fruit of the pepper plant, with the thin darker-coloured skin (flesh) of the fruit removed. This is usually accomplished by a process known as retting, where fully ripe red pepper berries are soaked in water for about a week so the flesh of the peppercorn softens and decomposes; rubbing then removes what remains of the fruit, and the naked seed is dried. Sometimes the outer layer is removed from the seed through other mechanical, chemical, or biological methods.[10]
Ground white pepper is commonly used in Chinese, Thai, and Portuguese cuisines. It finds occasional use in other cuisines in salads, light-coloured sauces, and mashed potatoes as a substitute for black pepper, because black pepper would visibly stand out. However, white pepper lacks certain compounds present in the outer layer of the drupe, resulting in a different overall flavour.[citation needed]
Green pepper, like black pepper, is made from unripe drupes. Dried green peppercorns are treated in a way that retains the green colour, such as with sulfur dioxide, canning, or freeze-drying. Pickled peppercorns, also green, are unripe drupes preserved in brine or vinegar.
Fresh, unpreserved green pepper drupes are used in some cuisines like Thai cuisine and Tamil cuisine. Their flavour has been described as "spicy and fresh", with a "bright aroma."[11] They decay quickly if not dried or preserved, making them unsuitable for international shipping.
Red peppercorns usually consist of ripe peppercorn drupes preserved in brine and vinegar. Ripe red peppercorns can also be dried using the same colour-preserving techniques used to produce green pepper.[12]
Pink peppercorns are the fruits of the Peruvian pepper tree, Schinus molle, or its relative, the Brazilian pepper tree, Schinus terebinthifolius, plants from a different family (Anacardiaceae). As they are members of the cashew family, they may cause allergic reactions, including anaphylaxis, for persons with a tree nut allergy.
The bark of Drimys winteri ("canelo" or "winter's bark") is used as a substitute for pepper in cold and temperate regions of Chile and Argentina, where it is easily found and readily available. In New Zealand, the seeds of kawakawa (Piper excelsum), a relative of black pepper, are sometimes used as pepper; the leaves of Pseudowintera colorata ("mountain horopito") are another replacement for pepper. Several plants in the United States are also used as pepper substitutes, such as field pepperwort, least pepperwort, shepherd's purse, horseradish, and field pennycress.
Pepper can be grown in soil that is neither too dry nor susceptible to flooding, moist, well-drained, and rich in organic matter (the vines do not do well over an altitude of 900 m (3,000 ft) above sea level). The plants are propagated by cuttings about 40 to 50 cm (16 to 20 in) long, tied up to neighbouring trees or climbing frames at distances of about 2 m (6 ft 7 in) apart; trees with rough bark are favoured over those with smooth bark, as the pepper plants climb rough bark more readily. Competing plants are cleared away, leaving only sufficient trees to provide shade and permit free ventilation. The roots are covered in leaf mulch and manure, and the shoots are trimmed twice a year. On dry soils, the young plants require watering every other day during the dry season for the first three years. The plants bear fruit from the fourth or fifth year, and then typically for seven years. The cuttings are usually cultivars, selected both for yield and quality of fruit.[citation needed]
A single stem bears 20 to 30 fruiting spikes. The harvest begins as soon as one or two fruits at the base of the spikes begin to turn red, and before the fruit is fully mature, and still hard; if allowed to ripen completely, the fruits lose pungency, and ultimately fall off and are lost. The spikes are collected and spread out to dry in the sun, then the peppercorns are stripped off the spikes.[13]
Wild pepper grows in the Western Ghats region of India. Into the 19th century, the forests contained expansive wild pepper vines, as recorded by the Scottish physician Francis Buchanan (also a botanist and geographer) in his book A journey from Madras through the countries of Mysore, Canara and Malabar (Volume III).[16] However, deforestation resulted in wild pepper growing in more limited forest patches from Goa to Kerala, with the wild source gradually decreasing as the quality and yield of the cultivated variety improved. No successful grafting of commercial pepper on wild pepper has been achieved to date.[16]
In 2020, Vietnam was the world's largest producer and exporter of black peppercorns, producing 270,192 tonnes or 36% of the world total (table).[17] Other major producers were Brazil, Indonesia, India, Sri Lanka, China, and Malaysia. Global pepper production varies annually according to crop management, disease, and weather.[18] Peppercorns are among the most widely traded spice in the world, accounting for 20% of all spice imports.[19]
Black pepper is native to South Asia and Southeast Asia, and has been known to Indian cooking since at least 2000 BCE.[20][how?] J. Innes Miller notes that while pepper was grown in southern Thailand and in Malaysia,[when?] its most important source was India, particularly the Malabar Coast, in what is now the state of Kerala.[21] The lost ancient port city of Muziris in Kerala, famous for exporting black pepper and various other spices, gets mentioned in a number of classical historical sources for its trade with Roman Empire, Egypt, Mesopotamia, Levant, and Yemen.[22][23][24][25] Peppercorns were a much-prized trade good, often referred to as "black gold" and used as a form of commodity money. The legacy of this trade remains in some Western legal systems that recognize the term "peppercorn rent" as a token payment for something that is, essentially, a gift.[citation needed]
Black peppercorns were found stuffed in the nostrils of Ramesses II, placed there as part of the mummification rituals shortly after his death in 1213 BCE.[27] Little else is known about the use of pepper in ancient Egypt and how it reached the Nile from the Malabar Coast of South Asia.
By the time of the early Roman Empire, especially after Rome's conquest of Egypt in 30 BCE, open-ocean crossing of the Arabian Sea direct to Chera dynasty southern India's Malabar Coast was near routine. Details of this trading across the Indian Ocean have been passed down in the Periplus of the Erythraean Sea. According to the Greek geographer Strabo, the early empire sent a fleet of around 120 ships on an annual trip to India and back.[28] The fleet timed its travel across the Arabian Sea to take advantage of the predictable monsoon winds. Returning from India, the ships travelled up the Red Sea, from where the cargo was carried overland or via the Nile-Red Sea canal to the Nile River, barged to Alexandria, and shipped from there to Italy and Rome. The rough geographical outlines of this same trade route would dominate the pepper trade into Europe for a millennium and a half to come.
With ships sailing directly to the Malabar coast, Malabar black pepper was now travelling a shorter trade route than long pepper, and the prices reflected it. Pliny the Elder's Natural History tells us the prices in Rome around 77 CE: "Long pepper ... is 15 denarii per pound, while that of white pepper is seven, and of black, four." Pliny also complains, "There is no year in which India does not drain the Roman Empire of 50 million sesterces", and further moralizes on pepper:
It is quite surprising that the use of pepper has come so much into fashion, seeing that in other substances which we use, it is sometimes their sweetness, and sometimes their appearance that has attracted our notice; whereas, pepper has nothing in it that can plead as a recommendation to either fruit or berry, its only desirable quality being a certain pungency; and yet it is for this that we import it all the way from India! Who was the first to make trial of it as an article of food? and who, I wonder, was the man that was not content to prepare himself by hunger only for the satisfying of a greedy appetite?
He does not state whether the 50 million was the actual amount of money which found its way to India or the total retail cost of the items in Rome, and, elsewhere, he cites a figure of 100 million sesterces.[28]
Black pepper was a well-known and widespread, if expensive, seasoning in the Roman Empire. Apicius' De re coquinaria, a third-century cookbook probably based at least partly on one from the first century CE, includes pepper in a majority of its recipes. Edward Gibbon wrote, in The History of the Decline and Fall of the Roman Empire, that pepper was "a favorite ingredient of the most expensive Roman cookery".[30]
