Hot chocolate (also known as hot cocoa, drinking chocolate, or just cocoa) is a heated beverage that typically consists of shaved chocolate or cocoa powder, heated milk or water, and sugar. While hot chocolate is generally thought of as a drink consumed for pleasure, recent studies have suggested that hot chocolate possesses health benefits due to antioxidants that can be found in cocoa. Until the 19th century, hot chocolate was even used medicinally to treat ailments such as stomach diseases.

The first chocolate beverage is believed to have been created by the Mayan peoples around 2000 years ago, and a cocoa beverage was an essential part of Aztec culture by 1400 A.D. The beverage became popular in Europe after being introduced from Mexico in the New World, and has undergone multiple changes since then. Today, hot chocolate is consumed throughout the world and comes in multiple variations including the very thick cioccolata densa served in Italy, and the thinner hot cocoa that is typically consumed in the United States.

History

Chocolate is made from cocoa, the dried and partially fermented seeds of the cacao tree (Theobroma cacao), a small (4–8 m (or 15–26 ft) tall) evergreen tree native to the deep tropical region of the Americas. Recent genetic studies suggest that the most common genotype of the plant originated in the Amazon basin and was gradually transported by humans throughout South and Central America. Early forms of another genotype have also been found in what is now Venezuela. The scientific name, Theobroma, means "food of the gods". The fruit, called a cacao pod, is ovoid, 15–30 cm (or 6–12 in) long and 8–10 cm (3–4 in) wide, ripening yellow to orange, and weighs about 500 g (1 lb) when ripe.

The chocolate residue found in jars from the site of Puerto Escondido in Honduras from around 1100 B.C. is the earliest found evidence of the use of cacao to date. An early Classic (460-480 A.D.) period Mayan tomb from the site of Rio Azul, Guatemala, had vessels with the Maya glyph for cacao on them with residue of a chocolate drink. The Maya are generally given credit for creating the first modern chocolate beverage over 2,000 years ago, despite the fact that the beverage would undergo many more changes in Europe.

By the 1400s, the Aztecs gained control of a large part of Mesoamerica, and adopted cacao into their culture. They associated chocolate with Xochiquetzal, the goddess of fertility, and often used chocolate beverages as sacred offerings. The Aztec adaptation of the drink was a bitter, frothy, spicy drink called xocolatl, made much the same way as the Mayan chocolate drinks. It was often seasoned with vanilla, chile pepper, and achiote, and was believed to fight fatigue, which is probably attributable to the theobromine content, a mood enhancer. Because cacao would not grow in the dry central Mexican highlands and had to be imported, chocolate was an important luxury good throughout the Aztec empire, and cocoa beans were often used as currency.
