Chocolate







Chocolate (pronounced /ˈtʃɑklɪt/ (help·info), British English: /ˈtʃɒklət/; it originates from a Nahuatl word meaning "bitter water") comprises a number of raw and processed foods that originate from the seed of the tropical cacao tree. It is a common ingredient in many kinds of confections such as chocolate bars, candy, ice cream, cookies, cakes, pies, chocolate mousse, and other desserts.
It is one of the most popular and recognizable flavours in the world.
Chocolate is made from the
fermented, roasted, and ground seeds taken from the pod of the tropical cacao tree, Theobroma cacao.
The tree is native to lowland tropical South America but is now cultivated throughout the tropics.
The seeds have an intense bitter taste, and must be fermented to develop the chocolate flavor.
The resulting products are known as "chocolate" or, in some parts of the world, cocoa.
Chocolate, or cacao, beverages were made by many
Mesoamerican civilizations in antiquity, including the Maya and the Aztecs.
The fermented seeds of the Theobroma cacao tree were ground and mixed with other ingredients such as honey, chile peppers, water, and the ground seeds of other plants.
Today, chocolate commonly refers to bars made from the combination of
cocoa solids, fat (usually cocoa butter), sugar and other ingredients.
Chocolate bars have a melting point just below body temperature.
Chocolate contains alkaloids such as theobromine and phenethylamine, and has numerous physiological effects on the body: it has been linked with serotonin levels in the brain.
The presence of theobromine renders it toxic to some animals such as dogs.
Chocolate is often produced as small molded forms in the shape of squares, animals, people, or inanimate objects to celebrate festivals worldwide.
For example, there are moulds of rabbits or eggs for Easter, coins for Hanukkah, Saint Nicholas (Santa Claus) for Christmas, and hearts for Valentine's Day. Chocolate can also be made into drinks (called cocoa and hot chocolate), as originated by the Aztecs and the Mayas.
In England, Samuel Pepys records in his diaries at least two entries relating to "jocolatte" as early as the 1660s. Later, in 1689 Hans Sloane developed a milk chocolate drink in Jamaica initially used by apothecaries, but later sold by the Cadbury brothers.

History
The word "chocolate" comes from the Nahuatl language of the Aztecs of Mexico. The word is derived from the Nahuatl word xocolatl (IPA /ʃo'kola:tɬ/), which is a combination of the words, xocolli, meaning "bitter", and atl, which is "water".
The Aztecs associated chocolate with Xochiquetzal, the goddess of fertility. Chocolate is also associated with the Mayan god of Fertility. Mexican philologist Ignacio Davila Garibi, proposed that "Spaniards had coined the word by taking the Maya word chocol and then replacing the Maya term for water, haa, with the Aztec one, atl.
" However, it is more likely that the Aztecs themselves coined the term, having long adopted into Nahuatl the Mayan word for the "cacao" bean; the Spanish had little contact with the Mayans before Cortés's early reports to the Spanish King of the beverage known as xocolatl.
However, Micheal D. Coe, professor Emeritus of Anthropology and Curator Emeritus in the Peabody Museum of Natural History at Yale University, and coauthor of the book The True History of Chocolate, argues that the word xocolatl appears in "no truly early source on the Nahuatl language or on Aztec culture."
The earliest record of using chocolate pre-dates the Mayans. Chocolate residue has been found in pottery dating to 1100 BC from Honduras,
and 600-400 BC from Belize.
The chocolate residue found in an early classic ancient Maya pot in Río Azul, northern Guatemala, suggests that Mayans were drinking chocolate around 400 A.D.. Chocolate has been used solely as a drink for nearly all of its history.
In the New World, chocolate was consumed in a bitter, spicy drink called xocoatl, and was often flavored with vanilla, chile pepper, and achiote, (which is known today as annatto).
Xocoatl was believed to fight fatigue, a belief that is probably attributable to the theobromine content.
Other chocolate drinks combined it with such edibles as maize starch paste (which acts as an emulsifier and thickener), various fruits, and honey.
Chocolate was an important luxury good throughout
pre-Columbian Mesoamerica, and cacao beans were often used as currency.
For example, the Aztecs used a system in which one turkey cost one hundred cacao beans and one avocado was worth three beans.
In 1689 noted
physician and collector Hans Sloane, developed a milk chocolate drink in Jamaica which was initially used by apothecaries, but later sold by the Cadbury
brothers.
