A nutshell is the outer shell of a nut. Most nutshells are inedible and are removed before eating the nut meat inside. It covers and protects the kernel, which may be edible.

Most nutshells are useful to some extent, depending on the circumstances. Walnut shells can be used for cleaning and polishing, as a filler in dynamite, and as a paint thickening agent. [1] [ circular reference ] Shells from pecans, almonds, Brazil nuts, acorns, and most other nuts are useful in composting. [2] Their high porosity makes them also ideal in the production of activated carbon by pyrolysis. Shells can also be used as loose-fill packing material, to protect fragile items in shipping.
The expression "in a nutshell" (of a story, proof, etc.) means "in essence", metaphorically alluding to the fact that the essence of the nut - its edible part - is contained inside its shell. The expression further gave rise to the journalistic term nut graph , short for nutshell paragraph.
In Hamlet (Act 2, Scene 2) the title character exclaims: "O God, I could be bounded in a nutshell, and count myself a King of infinite space".
Pliny the Elder mentioned in the encyclopedic Naturalis historia a report by Cicero saying that a handwritten version of the Iliad by Homer would have fit in a nut[shell]: "in nuce inclusam Iliadem Homeri carmen in membrana scriptum tradit Cicero". [3]
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.
Cashew is the common name of a tropical evergreen tree Anacardium occidentale, in the family Anacardiaceae. It is native to South America and is the source of the cashew nut and the cashew apple, an 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 nut is edible and is eaten on its own as a snack, used in recipes, or processed into cashew cheese or cashew butter. The nut is often simply called a 'cashew'. Cashew can cause allergies triggered by the proteins found in the nuts.
Walnut trees are any species of tree in the plant genus Juglans, the type genus of the family Juglandaceae, the seeds of which are referred to as walnuts. All species are deciduous trees, 10–40 metres (33–131 ft) tall, with pinnate leaves 200–900 millimetres (7.9–35.4 in), with 5–25 leaflets; the shoots have chambered pith, a character shared with the wingnuts (Pterocarya), but not the hickories (Carya) in the same family.
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 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 and weigh as much as 2 kg (4.4 lb) in total. 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 US, they are also known as Hawaii nut. It was an important source of bushfood for the Aboriginal peoples.
Pine nuts, also called piñón, pinoli, or pignoli, 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. The biggest producers of pine nuts are China, Russia, North Korea, Pakistan and Afghanistan.
Corylus avellana, the common hazel, is a species of flowering plant in the birch family Betulaceae, native to Europe and Western Asia. It is an important component of the hedgerows that were, historically, used as property and field boundaries in lowland England. The wood was traditionally grown as coppice, with the poles cut being used for wattle-and-daub building, and agricultural fencing.
Juglans nigra, the eastern American black walnut, is a species of deciduous tree in the walnut family, Juglandaceae, native to North America. It grows mostly in riparian zones, from southern Ontario, west to southeast South Dakota, south to Georgia, northern Florida and southwest to central Texas. Wild trees in the upper Ottawa Valley may be an isolated native population or may have derived from planted trees.
Juglans regia, the Persian walnut, English walnut, Carpathian walnut, Madeira walnut, or, especially in Great Britain, common walnut, is an Old World walnut tree species native to the region stretching from the Caucasus eastward to the Kashmir region. It is widely cultivated across Asia, Northern America and Europe.
Canarium ovatum, the pili, is a species of tropical tree belonging to the genus Canarium. It is one of approximately 600 species in the family Burseraceae. C. ovatum are native to the Philippines. They are commercially cultivated in the Philippines for their edible nuts and is believed to be indigenous to that country. The fruit and tree are often vulgarized with the umbrella term of "Java almond" which mixes multiple species of the same genus, Canarium.
Juglans neotropica is a species of plant in the Juglandaceae family. It is found in Colombia, Ecuador, and Peru. It is threatened by habitat loss. Common names include Colombian walnut, Ecuadorian walnut, Andean walnut, nogal, cedro negro, cedro nogal, and nogal Bogotano.
A walnut is the edible seed of any tree of the genus Juglans, particularly the Persian or English walnut, Juglans regia. They are accessory fruit because the outer covering of the fruit is technically an involucre and thus not morphologically part of the carpel; this means it cannot be a drupe but is instead a drupe-like nut.
The pecan weevil, Curculio caryae is an obligate feeder on the nuts of North American hickories and pecans, most widely recognized as an economically important pest of the pecan, Carya illinoinensis. It has also been observed to infest one Juglans species, the Persian walnut, Juglans regia.
Plukenetia conophora, also called Nigerian walnut, and conophore, is a climbing shrub in the genus Plukenetia. It is not related to the walnut, being so named because its nuts bear a superficial resemblance to the walnut. It is native to tropical western and central Africa from Togo to Congo and in Sierra Leone. It is abundant in the Nigeria, Cameroon, Republic of the Congo and Democratic Republic of Congo. It prefers rain-forest hedge in half-shady places; low bush; secondary forest; plantations at elevations from 250–1,400 m (820–4,590 ft). Although it is well recorded in Sierra Leone, it is apparently not indigenous to Sierra Leone, since it is not recorded in Liberia and Ghana. Its presence in Sierra Leone is due to returning slaves for it is known to the Krio by its Yoruba (Nigerian) name. Plukenetia conophora is the only Plukenetia species native to West Africa or Central Africa. Other Plukenetia species are indigenous to other parts of Africa, the Indian Subcontinent, Southeast Asia, and America.
Husk in botany is the outer shell or coating of a seed. In the United States, the term husk often refers to the leafy outer covering of an ear of maize (corn) as it grows on the plant. Literally, a husk or hull includes the protective outer covering of a seed, fruit, or vegetable.
All in a Nutshell is a Donald Duck animated short film produced by Walt Disney Productions and originally released on 1949 by RKO Radio Pictures in Technicolor.
Canarium indicum, known as galip nut, is a mainly dioecious tree native in eastern Melanesia. It is usually found in rainforests, secondary forests, old garden areas, around villages and settlements. It is also used as a shade tree, as a windbreak and in agroforestry. Canarium is important in the world food system as it can be used as a food and timber source, in traditional medicine, intercropping and agroforestry.
