Walnuts are the large wrinkled edible seeds of a deciduous tree. It consists of two halves that are enclosed within a hard shell. The tall deciduous trees produce walnuts with compound leaves and valuable ornamental timber that is used chiefly in cabinet making and gun stocks.
A walnut is the edible seed of a drupe of any tree of the genus Juglans and family Juglandaceae, particularly the Persian or English walnut, Juglans regia.
Walnuts are rounded, single-seeded stone fruits of the walnut tree commonly used for food after fully ripening between September and November. Walnut trees are late to grow leaves, typically not leafing out until more than halfway through the spring. They emit chemicals into the soil to prevent competing vegetation from growing. Because of this, susceptible plants should not be planted close to them.

During the Byzantine era, the walnut was also known by the name "royal nut".
The two most common major species of walnuts are grown for their seeds: the Persian or English walnut and the black walnut. The English walnut (J. Regia) originated in Iran (Persia), and the black walnut (J. nigra) is native to eastern North America. The black walnut is of high flavor, but due to its hard shell and poor hulling characteristics, it is not commercially cultivated in orchards.
Numerous walnut cultivars have been developed commercially, which are nearly all hybrids of the English walnut.


How to eat walnut?

Walnut meats are available in two forms: in their shells or de-shelled. The meats may be whole, halved, or in smaller portions due to processing. All walnuts can be eaten on their own (raw, toasted, or pickled), or as part of a mix such as muesli, or as an ingredient of a dish: e.g. walnut soup, walnut pie, walnut coffee cake, banana cake, brownie, fudge. Walnuts are often candied or pickled. Pickled walnuts that are the whole fruit can be savory or sweet depending on the preserving solution.
Walnuts may be used as an ingredient in other foodstuffs. Walnut is an important ingredient in baklava, Circassian chicken, chicken in walnut sauce, and poultry or meatball stew from Iranian cuisine.
Walnuts are also popular as an ice cream topping, and walnut pieces are used as a garnish on some foods.
Nocino is a liqueur made from unripe green walnuts steeped in alcohol with syrup added.
Walnut oil is available commercially and is chiefly used as a food ingredient, particularly in salad dressings. It has a low smoke point, which limits its use for frying.
