Peach

The peach (Prunus persica) is a deciduous tree native to the region of Northwest China between the Tarim Basin and the north slopes of the Kunlun Shan mountains, where it was first domesticated and cultivated. It bears an edible juicy fruit called a peach or a nectarine.

The specific epithet persica refers to its widespread cultivation in Persia, whence it was transplanted to Europe. It belongs to the genus Prunus which includes the cherry, apricot, almond and plum, in the rose family. The peach is classified with the almond in the subgenus Amygdalus, distinguished from the other subgenera by the corrugated seed shell.

Peach and nectarines are the same species, even though they are regarded commercially as different fruits. In contrast to peaches, whose fruits present the characteristic fuzz on the skin, nectarines are characterized by the absence of fruit-skin trichomes (fuzz-less fruit); genetic studies suggest nectarines are produced due to a recessive allele, whereas peaches are produced from a dominant allele for fuzzy skin.

Black

Black is the darkest color, the result of the absence of or complete absorption of light. It is the opposite of white (the combined spectrum of color or light). It is an achromatic color, literally a color without color or hue. It is one of the four primary colors in the CMYK color model, along with cyan, yellow, and magenta, used in color printing to produce all the other colors.

Black was one of the first colors used by artists in neolithic cave paintings. In the 14th century, it began to be worn by royalty, the clergy, judges and government officials in much of Europe. It became the color worn by English romantic poets, businessmen and statesmen in the 19th century, and a high fashion color in the 20th century.

In the Roman Empire, it became the color of mourning, and over the centuries it was frequently associated with death, evil, witches and magic. According to surveys in Europe and North America, it is the color most commonly associated with mourning, the end, secrets, magic, force, violence, evil, and elegance.

Juice

Juice is a liquid (drink) that is naturally contained in fruit and vegetables. It can also refer to liquids that are flavored with these or other biological food sources such as meat and seafood. It is commonly consumed as a beverage or used as an ingredient or flavoring in foods. It is also a common practice to mix juices of different fruits/vegetables. Juice did not emerge as a popular beverage choice until the development of pasteurization methods allowed for the preservation of juice without fermentation. The Food and Agriculture Organization of the United Nations (FAO) estimated the total world production of citrus fruit juices to be 12,840,318 tonnes in 2012.

Preparation

Juice is prepared by mechanically squeezing or macerating (sometimes referred to as cold pressed) fruit or vegetable flesh without the application of heat or solvents. For example, orange juice is the liquid extract of the fruit of the orange tree, and tomato juice is the liquid that results from pressing the fruit of the tomato plant. Juice may be prepared in the home from fresh fruit and vegetables using a variety of hand or electric juicers.

Peanut butter

Peanut butter, popular in many countries, is a food paste made primarily from ground dry roasted peanuts. Some varieties contain added salt, seed oils, emulsifiers, and sugar, whereas "natural" types of peanut butter consist solely of ground peanuts. It is mainly used as a sandwich spread, sometimes in combination with other spreads such as jam, honey, chocolate (in various forms), vegetables or cheese. The United States is a leading exporter of peanut butter and consumes $800 million worth annually. Nuts are also prepared comparably as nut butters.

History

Peanut butter dates back to the Aztecs and the Incas.

Canadian Marcellus Gilmore Edson (February 7, 1849 – March 6, 1940) of Montreal, Quebec was the first to patent peanut butter, in 1884. Peanut flour already existed. His cooled product had "a consistency like that of butter, lard, or ointment" according to his patent application. He included the mixing of sugar into the paste so as to harden its consistency.

Edson, a chemist (pharmacist), developed the idea of peanut paste as a delicious and nutritious staple for people who could hardly chew on solid food, a not uncommon state back in those days. Peanut paste was initially sold for six cents per pound.

Peanut butter and jelly sandwich

The peanut butter and jelly sandwich, or PB&J, is a sandwich, popular in North America, that includes a layer of peanut butter and either jelly or jam on bread, commonly between two slices of bread, but sometimes eaten open-faced or with one slice folded over.

A 2002 survey showed the average American will have eaten 1,500 of these sandwiches before high school graduation.

History

Peanut butter was first paired with a diverse set of foods, such as pimento, nasturtium, cheese, celery, watercress, and on toasted crackers. In a Good Housekeeping article published in May 1896, a recipe "urged homemakers to use a meat grinder to make peanut butter and spread the result on bread." In June of that same year, the culinary magazine Table Talk published a "peanut butter sandwich recipe." The first reference of peanut butter paired with jelly on bread to be published in the United States was by Julia Davis Chandler in 1901 in the Boston Cooking-School Magazine of Culinary Science and Domestic Economics. In the early 1900s, this sandwich eventually moved down the class structure as the price of peanut butter dropped. It became popular with children. During World War II, it is said that both peanut butter and jelly were found on U.S. soldiers' military ration list, as claimed by the Peanut Board.
