Hazelnut

The hazelnut is the nut of the hazel and therefore includes any of the nuts deriving from species of the genus Corylus, especially the nuts of the species Corylus avellana. It also is known as cobnut or filbert nut according to species. A cob is roughly spherical to oval, about 15–25 mm (0.59–0.98 in) long and 10–15 mm (0.39–0.59 in) in diameter, with an outer fibrous husk surrounding a smooth shell. A filbert is more elongated, being about twice as long as its diameter. The nut falls out of the husk when ripe, about 7 to 8 months after pollination. The kernel of the seed is edible and used raw or roasted, or ground into a paste. The seed has a thin, dark brown skin, which sometimes is removed before cooking.

Hazelnuts are used in confectionery to make praline, and also used in combination with chocolate for chocolate truffles and products such as Nutella and Frangelico liqueur. Hazelnut oil, pressed from hazelnuts, is strongly flavoured and used as a cooking oil. Turkey is the world’s largest producer of hazelnuts.

The many cultivars of the hazel include ‘Atababa’, ‘Barcelona’, ‘Butler’, ‘Casina’, ‘Clark’, ‘Cosford’, ‘Daviana’, ‘Delle Langhe’, ‘England’, ‘Ennis’, ‘Fillbert’, ‘Halls Giant’, ‘Jemtegaard’, ‘Kent Cob’, ‘Lewis’, ‘Tokolyi’, ‘Tonda Gentile’, ‘Tonda di Giffoni’, ‘Tonda Romana’, ‘Wanliss Pride’, and ‘Willamette’. Some of these are grown for specific qualities of the nut, including large nut size, or early or late fruiting, whereas others are grown as pollinators. The majority of commercial hazelnuts are propagated from root sprouts. Some cultivars are of hybrid origin between common hazel and filbert.

Hazelnuts are rich in protein, monounsaturated fat, vitamin E, manganese, and numerous other essential nutrients (nutrition table below).

History

In 1995, evidence of large-scale Mesolithic nut processing, some 9,000 years old, was found in a midden pit on the island of Colonsay in Scotland. The evidence consists of a large, shallow pit full of the remains of hundreds of thousands of burned hazelnut shells. Hazelnuts have been found on other Mesolithic sites, but rarely in such quantities or concentrated in one pit. The nuts were radiocarbon dated to 7720+/-110BP, which calibrates to circa 6000 BC. Similar sites in Britain are known only at Farnham in Surrey and Cass ny Hawin on the Isle of Man.

This discovery gives an insight into communal activity and planning in the period. The nuts were harvested in a single year, and pollen analysis suggests the hazel trees were all cut down at the same time. The scale of the activity and the lack of large game on the island, suggest the possibility that Colonsay contained a community with a largely vegetarian diet for the time they spent on the island. The pit was originally on a beach close to the shore, and was associated with two smaller, stone-lined pits whose function remains obscure, a hearth, and a second cluster of pits.

The traditional method to increase nut production is called ‘brutting’, which involves prompting more of the trees’ energy to go into flower bud production, by snapping, but not breaking off, the tips of the new year shoots’ six or seven leaf groups from where they join with the trunk or branch, at the end of the growing season. The traditional term for an area of cultivated hazelnuts is a plat.
