A nutcracker is a tool designed to open nuts by cracking their shells. There are many designs, including levers, screws, and ratchets. The lever version is also used for cracking lobster and crab shells.
The areca nut is the fruit of the areca palm, which grows in much of the tropical Pacific, South Asia, Southeast Asia, and parts of east Africa. It is commonly referred to as betel nut, not to be confused with betel leaves that are often used to wrap it. Consumption has many harmful effects on health and is carcinogenic to humans. Various compounds present in the nut, including arecoline, contribute to histologic changes in the oral mucosa. It is known to be a major risk factor for cancers of the mouth and esophagus. As with chewing tobacco, use is discouraged by preventive efforts. Consumption by hundreds of millions of people worldwide – mainly of South Asian or Southeast Asian origins – has been described as a "neglected global public health emergency".
The cashew tree is a tropical evergreen tree native to South America in the genus Anacardium that produces the cashew seed and the cashew apple accessory fruit. The tree can grow as tall as 14 metres, but the dwarf cultivars, growing up to 6 m (20 ft), prove more profitable, with earlier maturity and greater yields. The cashew seed is commonly considered a snack nut eaten on its own, used in recipes, or processed into cashew cheese or cashew butter. Like the tree, the nut is often simply called a cashew. Cashew allergies are triggered by the proteins found in tree nuts, and cooking often does not remove or change these proteins.
The kola nut is the seed of certain species of plant of the genus Cola, placed formerly in the cocoa family Sterculiaceae and now usually subsumed in the mallow family Malvaceae. These cola species are trees native to the tropical rainforests of Africa. Their caffeine-containing seeds are about 5 centimetres (2.0 in) across and are used as flavoring ingredients in beverages applied to various carbonated soft drinks, from which the name cola originates.
A nut is a fruit consisting of a hard or tough nutshell protecting a kernel which is usually edible. In general usage and in a culinary sense, a wide variety of dry seeds are called nuts, but in a botanical context "nut" implies that the shell does not open to release the seed (indehiscent).
The hazelnut is the fruit of the hazel tree and therefore includes any of the nuts deriving from species of the genus Corylus, especially the nuts of the species Corylus avellana. They are also known as cobnuts or filberts according to species.
The Brazil nut is a South American tree in the family Lecythidaceae, and it is also the name of the tree's commercially harvested edible seeds. It is one of the largest and longest-lived trees in the Amazon rainforest. The fruit and its nutshell – containing the edible Brazil nut – are relatively large, possibly weighing as much as 2 kg (4.4 lb) in total weight. As food, Brazil nuts are notable for diverse content of micronutrients, especially a high amount of selenium. The wood of the Brazil nut tree is prized for its quality in carpentry, flooring, and heavy construction.
Macadamia is a genus of four species of trees in the flowering plant family Proteaceae. They are indigenous to Australia, native to northeastern New South Wales and central and southeastern Queensland specifically. Two species of the genus are commercially important for their fruit, the macadamia nut. Global production in 2015 was 160,000 tonnes. Other names include Queensland nut, bush nut, maroochi nut, bauple nut and, in the USA, they are also known as Hawaii nut. In Australian Aboriginal languages, the fruit is known by names such as bauple, gyndl or jindilli and boombera. It was an important source of bushfood for the Aboriginal peoples who are the original inhabitants of the area.
Pine nuts, also called piñón, pinoli, pignoli, bondoq or chilgoza, are the edible seeds of pines. According to the Food and Agriculture Organization, only 29 species provide edible nuts, while 20 are traded locally or internationally owing to their seed size being large enough to be worth harvesting; in other pines, the seeds are also edible but are too small to be of notable value as human food.
In rock climbing, a nut is a metal wedge threaded on a wire that climbers use for protection by wedging it into a crack in the rock. Quickdraws are clipped to the nut wire by the ascending climber and the rope threads through the quickdraw. Nuts come in a variety of sizes and styles, and several different brands are made by competing manufacturers. Most nuts are made of aluminum. Larger nuts may be threaded on Dyneema cord instead of wire, but this has become unusual.
A nut butter is a spreadable foodstuff made by grinding nuts into a paste. The result has a high fat content and can be spread like true butter, but is otherwise unrelated. Nut butters include:
A lug nut or wheel nut is a fastener, specifically a nut, used to secure a wheel on a vehicle. Typically, lug nuts are found on automobiles, trucks (lorries), and other large vehicles using rubber tires.
A castellated nut, sometimes referred to as a castle nut, is a nut with slots (notches) cut into one end. The name comes from the nut's resemblance to the crenellated parapet of a medieval castle. Castellated nuts are sometimes referred to incorrectly as castigated nuts.
Crunchy Nut is a breakfast cereal made by Kellogg's with flakes of corn, honey, three types of sugar, and chopped peanuts. The product was created by Kellogg's employees at their Trafford Park factory in Greater Manchester and first introduced in 1980.
A locknut, also known as a lock nut, locking nut, self-locking nut, prevailing torque nut, stiff nut or elastic stop nut, is a nut that resists loosening under vibrations and torque. Prevailing torque nuts have some portion of the nut that deforms elastically to provide a locking action. Free-spinning locknuts exist which carry the advantage of not requiring extra torque until seated.
A nut is a type of fastener with a threaded hole. Nuts are almost always used in conjunction with a mating bolt to fasten multiple parts together. The two partners are kept together by a combination of their threads' friction, a slight stretching of the bolt, and compression of the parts to be held together.
Brazil nut cake is a cake prepared using Brazil nuts as a primary ingredient. Coffeecake, shortcake, pound cake, fruitcake, brownies and torte cake may be prepared using Brazil nuts as a main ingredient. Ground or chopped Brazil nuts may be used. Brazil nut cake is a dish in Brazilian cuisine, and it is a common and popular cake in the Amazon region of Bolivia, Brazil and Peru.
Kanuchi is a hickory nut soup eaten originally by the Cherokee people and which consists primarily of ground hickory nuts boiled in water. Hickory was the nut of choice, since it is a nut tree endemic to North America, and is known to grow plentifully in those forested areas settled by the Cherokee.
