Chili pepper in the context of "Scoville scale"

Pungency (/ˈpʌndʒənsi/ PUN-jən-see), commonly referred to as spiciness, hotness or heat, is a sensation that contributes to the flavor of certain foods such as chili peppers. Highly pungent foods may be experienced as unpleasant. The term piquancy (/ˈpiːkənsi/ PEEK-ən-see) is sometimes applied to foods with a lower degree of pungency that are "agreeably stimulating to the palate". In addition to chili peppers, piquant ingredients include wasabi, horseradish and mustard. The primary substances responsible for pungency are capsaicin (in chilis), piperine (in peppercorns) and allyl isothiocyanate (in radishes, mustard and wasabi).

The tomato (US: /təˈmeɪtoʊ/, UK: /təˈmɑːtoʊ/; Solanum lycopersicum) is a plant whose fruit is an edible berry that is eaten as a vegetable. The tomato is a member of the nightshade family that includes tobacco, potato, and chili peppers. It originated from western South America, and may have been domesticated there or in Mexico (Central America). It was introduced to the Old World by the Spanish in the Columbian exchange in the 16th century.

Tomato plants are vines, largely annual and vulnerable to frost, though sometimes living longer in greenhouses. The flowers are able to self-fertilise. Modern varieties have been bred to ripen uniformly red, in a process that has impaired the fruit's sweetness and flavor. There are thousands of cultivars, varying in size, color, shape, and flavor. Tomatoes are attacked by many insect pests and nematodes, and are subject to diseases caused by viruses and by mildew and blight fungi.

Eggplant (in North American, Australian, and Philippine English), aubergine (in British, Irish, and New Zealand English), brinjal (in Bangladeshi, Indian, Singapore, Malaysian, South African, and Sri Lankan English), or baigan (in Caribbean English) is a plant species in the nightshade family Solanaceae. Solanum melongena is grown worldwide for its edible fruit, typically used as a vegetable in cooking.

Most commonly purple, the spongy, absorbent fruit is used in several cuisines. It is a berry by botanical definition. As a member of the genus Solanum, it is related to the tomato, chili pepper, and potato, although those are of the Americas region while the eggplant is of the Eurasia region. Like the tomato, its skin and seeds can be eaten, but it is usually eaten cooked. Eggplant is nutritionally low in macronutrient and micronutrient content, but the capability of the fruit to absorb oils and flavors into its flesh through cooking expands its use in the culinary arts.

Indian cuisine consists of a variety of regional and traditional cuisines native to the Indian subcontinent. Given the diversity in soil, climate, culture, ethnic groups, and occupations, these cuisines vary substantially and use locally available ingredients.

Indian food is also heavily influenced by religion, in particular Hinduism and Sikhism, cultural choices and traditions. Historical events such as invasions, trade relations, and colonialism have played a role in introducing certain foods to India. The Columbian discovery of the New World brought a number of new vegetables and fruits. A number of these such as potatoes, tomatoes, chillies, peanuts, and guava have become staples in many regions of India.

Black pepper (Piper nigrum) is a flowering vine in the family Piperaceae, cultivated for its fruit (the peppercorn), which is usually dried and used as a spice and seasoning. The fruit is a drupe (stonefruit) which is about 5 mm (1⁄4 in) in diameter (fresh and fully mature), dark red, and contains a stone which encloses a single pepper seed. Peppercorns and the ground pepper derived from them may be described simply as pepper, or more precisely as black pepper (cooked and dried unripe fruit), green pepper (dried unripe fruit), or white pepper (ripe fruit seeds).

Black pepper is native to Southeast or South Asia. Ground, dried, and cooked peppercorns have been used since antiquity, both for flavour and as a traditional medicine. Black pepper is one of the most commonly traded spices in the world. Its spiciness is due to the chemical compound piperine, which is a different kind of spiciness from that of capsaicin characteristic of chilli 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.

Group C nerve fibers are one of three classes of nerve fiber in the central nervous system (CNS) and peripheral nervous system (PNS). The Group C fibers are unmyelinated and have a small diameter and low conduction velocity, whereas Groups A and B are myelinated. Group C fibers include postganglionic fibers in the autonomic nervous system (ANS), and nerve fibers at the dorsal roots (IV fiber). These fibers carry sensory information.

Damage or injury to nerve fibers causes neuropathic pain. Capsaicin activates C fibre vanilloid receptors, providing the burning sensation associated with chili peppers.

In physiology, nociception /ˌnəʊsɪˈsɛpʃ(ə)n/, also nocioception; from Latin nocere 'to harm/hurt') is the sensory nervous system's process of encoding noxious stimuli. It deals with a series of events and processes required for an organism to receive a painful stimulus, convert it to a molecular signal, and recognize and characterize the signal to trigger an appropriate defensive response.

In nociception, intense chemical (e.g., capsaicin present in chili pepper or cayenne pepper), mechanical (e.g., cutting, crushing), or thermal (heat and cold) stimulation of sensory neurons called nociceptors produces a signal that travels along a chain of nerve fibers to the brain. Nociception triggers a variety of physiological and behavioral responses to protect the organism against an aggression, and usually results in a subjective experience, or perception, of pain in sentient beings.

Kung Pao chicken (Chinese: 宮保雞丁; pinyin: Gōngbǎo jīdīng; Wade–Giles: Kung-pao chi-ting; Zhuyin Fuhao: ㄍㄨㄥ ㄅㄠˇ ㄐㄧ ㄉㄧㄥ), also transcribed Gong Bao or Kung Po, is a spicy, stir-fried Chinese dish made with cubes of cooked chicken, peanuts, vegetables and chili peppers, and Sichuan peppercorns. From its origins in Sichuan cuisine, the dish's popularity has spread throughout China, spawning a number of regional variations—some of which are less spicy than the classic version.

Chili oil or chile oil is a condiment made from vegetable oil that has been infused with chili peppers. Different types of oil and hot peppers are used, and other components may also be included. It is commonly used in Chinese cuisine, Mexico, Italy, and elsewhere. It is particularly popular in Chinese cuisine, especially western Chinese cuisines, such as Sichuan cuisine, Hunan cuisine, Guizhou cuisine, and Shaanxi cuisine, where it is used as an ingredient in cooked dishes, as well as as a condiment. It is sometimes used as a dip for meat and dim sum. It is also employed in the Korean Chinese noodle soup dish jjamppong. A closely related condiment in Chinese cuisine is chili crisp, which contains edible chunks of food and chilis in oil.

Chili oil is typically red in color. It is made from vegetable oil, often soybean oil or sesame oil, although olive oil or other oils may be used. Other spices may be included, such as Sichuan pepper, garlic, or paprika. Commercial preparations may include other kinds of oil, water, dried garlic, soy sauce, and sugar. Recipes targeted to Western cooks also suggest other popular oils, such as rapeseed, grapeseed or peanut, and any dried or fresh chili peppers. The solids typically settle to the bottom of the container in which it is stored. When using chili oil, the cook or diner may choose how much of the solids to use; sometimes only the oil is used, without any solids.

The bell pepper (also known as sweet pepper, paprika, pepper, capsicum /ˈkæpsɪkəm/ or, in some parts of the U.S. Midwest, mango) is the fruit of plants in the Grossum Group of the species Capsicum annuum. Cultivars of the plant produce fruits in different colors, including red, yellow, orange, green, white, and purple. Bell peppers are sometimes grouped with less pungent chili varieties as "sweet peppers". While they are botanically fruits—classified as berries—they are commonly used as a vegetable ingredient or side dish. Other varieties of the genus Capsicum are categorized as chili peppers when they are cultivated for their pungency, including some varieties of Capsicum annuum.

Peppers are native to Mexico, Central America, the Caribbean and northern South America. Pepper seeds were imported to Spain in 1493 and then spread through Europe and Asia. Preferred growing conditions for bell peppers include warm, moist soil in a temperature range of 21 to 29 °C (70 to 84 °F).
