Chayote

Chayote (Template:IPAc-en; previously placed in the obsolete genus Sechium), also known as christophine, mirliton, güisquil, and choko, is an edible plant belonging to the gourd family, Cucurbitaceae. This fruit was first cultivated in Mesoamerica between southern Mexico and Honduras, with the most genetic diversity available in both Mexico and Guatemala. It is one among dozens of foods introduced to the Old World during the Columbian Exchange. At that time, the plant spread to other parts of the Americas, ultimately causing it to be integrated into the cuisine of many Latin American nations.

The chayote fruit is mostly used cooked. When cooked, chayote is usually handled like summer squash; it is generally lightly cooked to retain the crispy consistency. Raw chayote may be added to salads or salsas, most often marinated with lemon or lime juice, but is often regarded as unpalatable and tough in texture. Whether raw or cooked, chayote is a good source of Vitamin C.

Although most people are familiar only with the fruit as being edible, the root, stem, seeds and leaves are edible as well. The tubers of the plant are eaten like potatoes and other root vegetables, while the shoots and leaves are often consumed in salads and stir fries, especially in Asia.

Names and etymology

The fruit goes by many English-language names around the world. "Chayote", the common American English name of the fruit (outside of Louisiana) is from the Spanish word , a derivative of the Nahuatl word (). The Nahuatl-derived name is preserved in the Philippines, where it is known as or . It is also known as in Guatemala, El Salvador, and in Honduras.

In Louisiana and Haiti it is known as "mirliton" (Template:IPAc-en) also spelled "mirleton" or "merleton" in the United Kingdom. The r is often silent, e.g. Cajun me-lay-taw).Template:Fv

In the eastern Caribbean, the United Kingdom and Ireland, it is known as "christophine" or "christophene" (from French, a reference to Christopher Columbus).

In other parts of the world, the English name is often "cho cho", "chouchou" (e.g. in Mauritius), or a variant thereof (e.g. "chow-chow" in India and Sri Lanka, "chuchu" in Brazil, and "chocho" in Jamaica). This name may have originated from Pidgin English for "chayote". In Nepal it is known as Es-kus.

In Australia, New Zealand and Singapore, it is known as "choko". The name is derived from Cantonese, from Chinese immigrants to Australia and New Zealand in the late 19th century.

Chayote is also sometimes referred to as "vegetable pear".

in Indonesia there are several names of chayote, labu (squash) siam, labu Jepang and manisah in Javanese. Beside the fruits, leaves are popular as a daily vegetables .

Chayote arrived to the southern Italian region of Campania in the early 16th Century. Spain conquered the Kingdom of Naples in 1503 and connected it to the wider network of commercial and military routes that included the American colonies. Chayote spread pretty rapidly but was never cultivated at scale. It is known in Naples markets as "melanzana dei francesi" (aubergine of the French) or "melanzana spinosa" (thorny aubergine) and "zucchina spinosa" (thorny zucchini), due to the fact that local varieties have thorns. Also known as "masciusce" (a name that suggests a connection with Brasilian "maxixe" and Kimbundu ma'xixi, indicating the thorny, tiny maroon cucumber), it is being "rediscovered" as a forgotten, local wild fruit and its colonial origins are still little known.

Cultivation

Like other members of the gourd family, chayote has a sprawling habit, and requires sufficient room. The roots are also highly susceptible to rot, especially in containers, and the plant in general is finicky to grow. However, in Australia and New Zealand it is an easily grown yard or garden plant, set on a chicken wire support or strung against a fence. In Trinidad and Tobago, it is grown in the mountainous areas strung from wire lines. In Latin America, chayote is widely cultivated. Depending on variety and region, yield reaches from 10 to 115 t/ha.

Soil and climate requirements

Chayote requires humus-rich, well drained soils, which are slightly acid to acid (pH 4.5 to 6.5). Clay soils reduce crop productivity because they retain water and therefore promote growth of fungal pests. Chayote adapts to a wide range of climatic conditions but grows best in regions with average temperatures of 13–21 °C with at least 1500–2000 mm of annual precipitation. The crop is not frost-tolerant, however it can be grown as an annual in temperate regions.

Taxonomy

The plant was first recorded by modern botanists in P. Browne's 1756 work, the Civil and Natural History of Jamaica. Swartz included it in 1800 in its current genus Sechium.

The genus name Sechium is probably an alteration of the Ancient Greek σίκυος : síkyos "cucumber". The species name edulis means "edible".

Description

In the most common variety, the fruit is roughly pear-shaped, somewhat flattened and with coarse wrinkles, ranging from Template:Cvt long, with thin green skin fused with green to white flesh, and a single, large, flattened stone. This seed or stone can be up to Template:Cvt long by Template:Cvt wide. Some varieties have spiny fruits. Depending on the variety, a single fruit can weigh up to 1.2 kg. The flesh has a fairly bland taste, and the texture is described as a cross between a potato and a cucumber.

The chayote vine can be grown on the ground, but as a climbing plant, it will grow onto anything, and can easily rise as high as Template:Cvt when support is provided. It has heart-shaped leaves, Template:Cvt wide and tendrils on the stem. The plant bears male flowers in clusters and solitary female flowers.

Culinary uses

Template:Sister project Although many people are familiar only with the fruit as being edible, the root, stem, seeds and leaves are edible as well. The tubers of the plant are eaten like potatoes and other root vegetables, while the shoots and leaves are often consumed in salads and stir-fries.

The fruit does not need to be peeled to be cooked or fried in slices. It has a very mild flavor. It is commonly served with seasonings (e.g., salt, butter and pepper in Australia) or in a dish with other vegetables and flavorings. It can also be boiled, stuffed, mashed, baked, fried, or pickled in escabeche sauce. Both fruit and seed are rich in amino acids and vitamin C. Fresh green fruit are firm and without brown spots or signs of sprouting; smaller fruit are usually more tender. Chayote can be sliced lengthwise and eaten using salad dressing dip. The seed is edible and tasty to some when served cold, dipped in dressing.

The tuberous part of the root is starchy and eaten like a yam; it can be fried. It can be used as pig or cattle fodder.

North America

Culinary use of the chayote in North America has tended to be regional. In Louisiana Creole and Cajun cuisine, the fruit is a popular seasonal dish for the holidays, especially around Thanksgiving, in a variety of recipes.

David Fairchild was a botanist who tried to introduce it to wider use in the southern United States, and describes the plant and early experiences with it in a journal article in 1947.

Ichintal (chayote root)

Chayote is an important part of traditional diets across Mesoamerica, and can be found in a variety of dishes. In this region, it is often known as güisquil, or huisquil, derived from the Nahuatl term huitzli. In Guatemala, güisquil specifically refers to the darker variety of the fruit, while the lighter, yellower variety is called perulero. The root, known as ichintal, is also a seasonal delicacy there. The fruit of the chayote is used in a type of Guatemalan chilaquiles called caldos, where a piece of cheese is placed between two slices of chayote and then dipped in egg batter and fried.

In Eastern Caribbean English the fruit, used as a vegetable, is known as christophene. In Jamaica and other places in the western Caribbean it is known as chocho. The fruit is called tayota in the Dominican Republic.

South America

In Brazil (locally called chuchu) and other Latin American countries, it is breaded and fried, or used cooked in salads, soups, stews and soufflés. 'Chuchu' (or 'Xuxú') is also a term of endearment in Brazil, like 'Honey' in English.

Chayote is widely used in Southeast Asia. In the Philippines, the plant is generally known as in Filipino (also , , , , , etc. in other Philippine languages, all derived from Spanish or ). It is grown mostly in mountainous parts of the country such as Benguet and parts of Cordillera Administrative Region. Chayote is used in many kinds of dishes such as soup (such as sinigang and tinola, often as a substitute for upo squash), stir-fried vegetables and chop suey. It was among the numerous vegetables, grains, and fruits introduced into the country directly from Mexico via the Manila galleon trade.

In Indonesia, chayotes or labu siam are widely planted for their shoots and fruit. (Labu siam, literally "Siamese gourd", is used in both Indonesia and Malaysia.) It is generally used in Sundanese food as lalap and one of ingredients for Sundanese cuisine called sayur asem, as well as one of ingredients for Javanese cuisine called sayur lodeh. In Timor-Leste, chayote is called lakeru Japones. It is speculated that chayote was introduced by Japanese soldiers during World War II. In Vietnam, chayote is called su su and is served in sautés, stir-fries and soups. In Thai cuisine, the plant is known as sayongte (Template:Langx) or fak maeo (Template:Langx, literally meaning "Miao melon"). It grows mainly in the mountains of northern Thailand. The young shoots and greens are often eaten stir-fried or in certain soups. In Burma, the chayote is known as Gurkha thee or "Gurkha fruit" () and is cheap and popular.

Chayote is also frequently eaten in South Asia. In eastern and north eastern India and Nepal, the plant and fruit is called squash or ishkus ( in Nepali), probably derived from the English word squash. Its shoots, fruit and roots are widely used for different varieties of curries. In the Indian state of West Bengal, it is generally known as squash (). The whole vegetable is used to make curries, or it is sauteed. It is also cooked with fish, eggs or mutton. It is largely eaten during the summer and rainy season as it contains much water and is a good source of vitamin C. The young branches are also considered for making items as saag or can be added into preparing shukto. There are two varieties available; dark green and light green. The dark green variety is much more tender than the lighter one, which develops a fibrous texture around its seed if harvesting or consumption is delayed. In Tamil Nadu, South India, chayote is known as maerakkai () or chow-chow () in Tamil and widely used in everyday cooking for recipes like sambar, kootu, poriyal, thuvayal, chutney and mor-kulambu. Chow-Chow is the common name used in the markets. In Karnataka, South India, chayote is popularly referred to as seeme badanekaayi () in Kannada or "Bangalore brinjal"; "brinjal/eggplant/aubergine of the plateau". It is used in vegetable stews like sambar and palya.

In temperate Northeast Asia, chayote is less common. In Korea, chayote is also known as chayote () and is commonly used as a side dish in either pickled or marinated form. This fruit is most commonly pickled with vinegar and soy sauce (chayote-jangajji; ), or marinated and dressed with sauces and spices into a salad (chayote-muchim; ). In China, the chayote is known as the "Buddha's palm" (Template:Lang-zh) or Template:Citation needed span or Template:Lang-zh, and is generally stir-fried. In tropical Taiwan and southern China, chayotes are widely planted for their shoots, known as lóngxūcài (Template:Lang-zh). Along with the young leaves, the shoots are a commonly consumed vegetable in the region.

Africa

Chayote is commonly eaten in the islands of the Indian Ocean. In Réunion, the French overseas territory near Mauritius, chou chou, as it is known, is served in many dishes especially in the highlands. A popular starter of chou chou au gratin (baked with a cheese sauce), as a side with a meal and even as a dessert. In Mauritius, it is called sousou and is cultivated in the high plateau of the island. Mixed with beef, pork or chicken, chou chou is widely used to make delicious steamed Chinese dumplings called niouk yen (boulette chou chou) or chow mai. Stems and leaves are consumed in bouillon to accompany rice and other dishes. The chou chou is also consumed as pickle, salad, gratin, curry and sauté with beef, egg or chicken. In Madagascar, chayote (known in Malagasy as sôsety) is eaten in dishes such as saosisy sy sôsety (sausage and chayote) and tilapia sy sôsety (tilapia and chayote).

Europe

In the Portuguese Autonomous Regions of Madeira and Azores, where the vegetable is popular, chayote is called pimpinela (or pepinela) and caiota, respectively. In both regions, chayote is part of the local gastronomy, usually cooked with beans in the shell, potatoes, and corn cobs to accompany fish dishes, usually caldeiradas. In the Azores, chayote is also used in puddings and jams. On the Mediterranean island of Malta, it is a popular vegetable grown mainly by hobby farmers or as a side-product. In the Maltese language, it is known as ċentinarja, and is mainly used in thick vegetable soups, or as a side-vegetable.

Folklore

Chayote as mock apple pie

In Australia, a persistent urban legend is that McDonald's apple pies were made of chokos (chayotes), not apples. This eventually led McDonald's to emphasise the fact that real apples are used in their pies. This legend was based on an earlier belief that tinned pears were often disguised chayotes. A possible explanation for the rumor is that there are a number of recipes in Australia that advise chayotes can be used in part replacement of canned apples to make the fruit go farther in making apple pies. This likely arose because of the economies of "mock" food substitutes during the Depression Era, shortages of canned fruit in the years following World War II, and the fact that apples do not grow in many tropical and subtropical parts of Australia, making them scarce. Chayotes, on the other hand, grow extensively in Australia, with many suburban backyards featuring chayote vines growing along their fence lines and outhouses.

Many modern keto diet recipes take advantage of chayote fruit's low carb count and apple-like cooked texture as a substitute in high-carb apple desserts.

Chayote as a mummification agent

Due to its purported cell-regenerative properties, it is believed as a contemporary legend that this fruit caused the mummification of people from the Colombian town of San Bernardo who extensively consumed it. The very well preserved skin and flesh can be seen in the mummies today.
