Peanuts (Groundnuts)
From their origins in South America to their addition to a plate of Mole Poblano.
A Brief History of Peanuts
Peanuts originate in South America, in what is now the Bolivia and Argentina Border, near the Andes mountains.
People in South America made pottery in the shape of peanuts or decorated jars with peanuts as far back as 3,500 years ago.
After their initial domestication, peanuts quickly spread to the rest of South America and Central America through trade, they were grown as far north as Mexico.
The arrival of the Spanish and Portuguese and the Columbian Exchange brought peanuts to Spain and Portugal during the fifteenth and sixteenth century.
Traders spread them to the rest of Europe, Asia and Africa.
"The peanut is first noted in the writings of Bartolomé de las Casas, who came to the Caribbean island of Hispaniola in 1502. Called mani by Native Americans, the peanut was considered a healthy food by the Caribbean islanders, but the Spanish considered it beneath their station to make it part of their own diet." (Poplar Grove Plantation)
During the early seventeenth century, Spanish trade ships carried the peanut to the Pacific Islands, the Philippines, and Indonesia.
At around the same time, Portuguese sailors began taking peanuts to the coast of West Africa.
The crop was well received in Africa due to its similarities to the native Bambara groundnut.
During the eighteenth century, peanuts were brought to the United States through the Transatlantic Slave Trade.
"At this time, peanuts were regarded as a food for livestock and the poor and were considered difficult to grow and harvest." (National Peanut Board)
Production grew during the nineteenth century when peanuts became a prominent snack among Civil War soldiers.
Peanuts became a significant agricultural crop when the boll weevil (a beetle which feeds on cotton) threatened the South’s cotton crop and following suggestions by scientist Dr. George Washington Carver to use them as a rotation crop.
Peanuts were then commodified after research discovered its multiple uses and following acceptance by the general public.
The twentieth century turned peanuts into a billion dollar industry with the assistance of corporations.
Peanuts Today
Though there are many varieties of peanuts, there are four primary market types:
- Runners: 54% of the runners grown are used for peanut butter. In the US, they're grown mainly in Georgia, Alabama, Florida, Texas and Oklahoma.
- Virginia: they account for most roasted and processed shelled peanuts. They're grown mainly in southeastern Virginia and northeastern North Carolina.
- Spanish: they're used mainly in peanut candies. They also have a higher oil content than the other peanuts. They're primarily grown in Oklahoma and Texas.
- Valencia: they're sweet, usually roasted, and sold shelled. New Mexico is their primary producer.
Peanut Production
Peanuts are grown worldwide in the warm climates of Asia, Africa, Australia, and North and South America.
India and China together account for more than half of the world's production. The United States has about 3% of the world acreage of peanuts, but grows nearly 10% of the world's crop because of higher yields per acre.
During 2017 to 2018, a grand total of 46.58 million metric tons were produced worldwide.
The biggest producers worldwide during the 2017 to 2018 period were China, India, Nigeria, and the United States with 17.09, 6.65, 4.25, and 3.23 million metric tons respectively
"Peanuts are the 12th most valuable cash crop grown in the United States with a farm value of over one billion U.S. dollars" (The American Peanut Council)
Peanuts in the United States are grown primarily for consumption, though they have other uses.
Peanuts are usually sold as snacks either shelled or roasted. Otherwise they're used to make peanut butter and peanut candy.
Americans eat more than six pounds of peanut products each year.
Peanuts are grown commercially in the following states: Alabama, Arkansas, Florida, Georgia, Louisiana, Missouri, Mississippi, North Carolina, New Mexico, Oklahoma, South Carolina, Texas and Virginia.
Georgia grows the largest proportion of all peanuts (46%). It's followed by Florida (nearly 13%), Alabama (nearly 11%) and Texas (nearly 9%).
Planting and Harvesting
Peanut seeds are planted about two inches underneath the soil, about three to four inches apart when the soil temperature is warm (65-70 °F).
They require long, warm and moist growing season and a dry harvest season. Depending on the variety of peanut, 120 to 160 frost free days are required for a good crop.
When the soil is neither too wet or dry, a farmer will drive a digger along the peanut rows. The digger pulls up the peanut plant with the roots, flips it upside down and sets it back down.
When dug, peanuts contain 25-50% moisture, which must be dried to 10% or less for storage.
They're left to dry for about five to seven days.Then they're picked up by a shaker or a picker and the peanut pods are separated from the rest of the plant.

Processing and Packaging
Peanuts are taken to shelling companies, where inspectors take a sample and review the content, size of pods, kernel size, moisture content, damaged kernels and foreign material.
Shellers purchase the peanuts they deem good quality/high in value and place them in dry storage for eventual sale to processors and manufacturers.
At shelling and processing plants, peanuts are taken from storage and cleaned by removing dirt, rocks, bits of vines and other debris.
If they're to be sold in their shells, the peanuts pass through a machine that cuts off any remaining stems.
If the shells are to be removed, they're placed in the shelling machine containing screens of different sizes. Rotating peanuts rub against each other until the shells are opened and the kernels fall out.
The kernels then pass over perforated grading screens where they are sorted by size into market grades.
Blanching is achieved by putting peanuts in hot water for a couple of minutes and then rubbing the skin off.
Distribution
Shellers or processing plants then sell peanuts to a manufacturer or "end user."
The manufacturer converts the peanuts to consumer products by roasting them, coating them with additional flavors, applying pressure to create oil, processing them into peanut butter and peanut candies, etc.
The finished products are then taken to food distribution centers like the Walmart Distribution Center located in Los Lunas, New Mexico and then to the rest of the Walmart's in the state. The peanut products are finally ready to be purchased and consumed.
The picture shows the majority of the Walmart's located in the city of Albuquerque. The stared location is where my family typically purchases peanuts.
Other Uses
The shells, skins and kernels of peanuts are sometimes used to make a variety of non-food products.
The shells may be used in wallboard, fireplace logs, fiber for livestock feed and kitty litter. The skins may be used for paper making.
Peanuts are often used as an ingredient in other products such as medicine, bleach, shaving cream, face creams, soap, shampoo, cosmetics, rubber, paint, ink, explosives and much more.
Consumption
Mole Poblano
Cinco de Mayo, which commemorates the 1862 Battle of Puebla is celebrated with great passion in the state and city of Puebla. A grand parade is carried out every year. The parade is accompanied by numerous dishes.
The state of Puebla (along with Oaxaca) claim to be the origin sites of mole. Mole is now considered a national Mexican dish. This was achieved through an attempt to characterize mole poblano as a culinary symbol of Mexico's mestizaje (racial mixing) of the indigenous peoples and Europeans.
"Although the word mole comes from the Nahuatl mulli, meaning sauce or potage, it has been pointed out by culinary anthropologists that very few of the ingredients in mole poblano were indigenous to the New World. The native chiles and chocolate, as well as the turkey itself, were indispensable in creating the dish, but almost all the spices were Old World ingredients." (Hursh Graber)
Special Food Interview
I interviewed my mom (pictured to the right). One of the dishes she holds dear to her heart is mole poblano since she cooked it on the day my dad went to ask for her hand in marriage. In addition to mole, she mentioned other dishes like chile colorado and chiles rellenos during the interview. The dishes all hold memories of her hometown (Santa Barbara, Chihuahua, Mexico), the people she shared them with and how far she’s come.
Peanuts are one of the many ingredients that form part of the mole sauce. However, they've always been an integral part of her family's take on the dish. The recipe was passed down from her grandma who was part Apache.
