General info about Fruit
The English Walnut (Juglans regia), also known as Common Walnut or Persian Walnut, is a species of walnut that is native to the Balkans, in southeast Europe, east through southwest and central Asia and the Himalayas to southwest China. The largest forests are in Kyrgyzstan, where English Walnut trees occur in extensive, nearly pure walnut forests at 1 000–2 000 m altitude (Hemery 1998)—notably at Arslanbob in Jalal-Abad Province.
English Walnut is a large deciduous tree attaining heights of 25–35 m, and a trunk up to 2 m diameter, commonly with a short trunk and broad crown, though taller and narrower in dense forest competition. It is a light-demanding species, requiring full sun to grow well.
The bark is smooth silvery-grey, with scattered broad fissures with a rougher texture. Like all walnuts, the pith of the twigs contains air spaces. The leaves are spirally arranged, 25-40 cm long, odd-pinnate with 5–9 leaflets, the largest leaflets the three at the apex, 10–18 cm long and 6–8 cm broad; the basal pair of leaflets much smaller, 5–8 cm long. The male flowers are in drooping catkins 5–10 cm long, the female flowers terminal, in clusters of two to five, ripening in the autumn into a fruit with a green, semi-fleshy husk and a brown corrugated nut. The whole fruit, including the husk, falls in autumn; the seed is large, with a relatively thin shell, and edible, with a rich flavour.

Ways to prepare and serve the Fruit
Edible Parts: Sap; Seed.
Edible Uses: Oil; Sweetener; Tea.
Seed - eaten raw or used in confections, cakes, ice cream etc. A delicious flavour. The seed can also be ground into a meal and used as a flavouring in sweet and savoury dishes. The unripe fruits are pickled in vinegar. An edible oil is obtained from the seed, it should not be stored for any length of time since it tends to go rancid quickly. The oil has a pleasant flavour and is used in salads or for cooking. The sap is tapped in spring and used to make a sugar. The finely ground shells are used in the stuffing of ‘agnolotti’ pasta. They have also been used as adulterant of spices. The dried green husks contain 2.5 - 5% ascorbic acid (vitamin C) - this can be extracted and used as a vitamin supplement. The leaves are used as a tea.

Dye; Herbicide; Miscellany; Oil; Paint; Polish; Repellent; Tannin; Teeth; Wood.
A yellow dye is obtained from the green husks. It is green. The green nuts (is this the same as the green husks?) and the leaves are also used. The rind of unripe fruits is a good source of tannin. A brown dye is obtained from the leaves and mature husks. It does not require a mordant and turns black if prepared in an iron pot. The dye is often used as a colouring and tonic for dark hair. The leaves and the husks can be dried for later use. A golden-brown dye is obtained from the catkins in early summer. It does not require a mordant. A drying oil is obtained from the seed. It is used in soap making, paints, etc. It is not very stable and quickly goes rancid. The nuts can be used as a wood polish. Simply crack open the shell and rub the kernel into the wood to release the oils. Wipe off with a clean cloth. The dried fruit rind is used to paint doors, window frames etc (it probably protects the wood due to its tannin content). The shells may be used as anti-skid agents for tyres, blasting grit, and in the preparation of activated carbon. The leaves contain juglone, this has been shown to have pesticidal and herbicidal properties. The crushed leaves are an insect repellent. Juglone is also secreted from the roots of the tree, it has an inhibitory effect on the growth of many other plants. Bark of the tree and the fruit rind are dried and used as a tooth cleaner. They can also be used fresh. Wood - heavy, hard, durable, close grained, seasons and polishes well. A very valuable timber tree, it is used for furniture making, veneer etc.
