History of chestnuts

Chestnut is a tree of the Beech family with the fruits of the same name. The thin woody-leathery shell of the fruit hides the nut, the edible part of the chestnut. Chestnuts were grown in Ancient Greece and Ancient Rome.

The Romans used them for food, and the Greeks used them as medicine. The Romans brought chestnuts to Britain. From Europe, chestnuts have spread throughout the world.

Chestnut trees have been growing on our planet since prehistoric times. The first mention of the plant dates back to 378 BC.

Other names for this plant are stomach or esculus.

In folk medicine, the juice squeezed from fresh flowers is used internally for vasodilation on the legs and for hemorrhoids.

But the edible sowing chestnut belongs to a completely different family. It grows mainly in the Mediterranean, the Black Sea region of Asia Minor and the Caucasus. In Ukraine, wild chestnut is found in the Crimea. True, the “civilized” European varieties that are grown in Italy, France or Spain are much larger – the size of a mandarin.

How does an edible chestnut look like?

It can be distinguished by its long, toothed leaves, which are attached to the handle not by an asterisk, but one by one. The trees reach 40 meters in height, and the flowers are ordinary-looking spikelets of yellowish color. The capsule of the fruit is covered with a large number of thin long thorns, and inside (unlike the single horse chestnut) there are 2-4 nuts in the shape of a bulb at once.

The edible nuts themselves are outwardly slightly similar to the fruits of horse chestnut. It is a large, flattened (sometimes almost flat) nut with a thin dark brown shell. The kernel of such a chestnut is white with a sweetish pulp – when fried, its taste resembles dry, crumbly potatoes.

 

Interesting fact: For chestnut trees, 500 years old is not a record. This plant has existed since prehistoric times. In the 4th century BC. the Romans actively cultivated chestnuts by grinding nuts into flour for baking bread.
