For many of us, the origin of black garlic is a mystery. In this article, you will learn: what is black garlic, how does black garlic differ from ordinary garlic, evaluate simple and healthy recipes with this exotic vegetable, and also learn how to prepare black garlic at home.

What is black garlic?

Black garlic is not a special variety, but a clove of regular fermented garlic. The final product does not have the usual garlic smell, is sweet in taste, and has a texture reminiscent of dried fruits. You can see black garlic in almost every menu around the world. It is so much popular nowadays.

However, black garlic is nothing new. It is being used in many Asian cuisines for more than hundred years. It is also used in ayurvedic treatment. People from other corners of the world do not know much about black garlic and for this reason they often ask or search on google: what is black garlic.

Black garlic is basically normal white garlic which is treated in a special way. You have to maintain proper temperature and humidity to prepare black garlic. We will tell about this in the following section.

How to get black garlic?

Black garlic is not a vegetable that is grown separately or differently. Rather it is basically the ordinary white garlic which has gone through prolonged heating. And of course the heating process was cautiously maintained. This process is basically a fermentation process that allows the garlic to release melanoidin naturally and becomes black in colour.

Black garlic is one of the rarest ingenious finds. It happened in Ancient Korea: people accidentally noticed that after lying for a long time in warm, slightly damp straw, garlic begins to turn black, but does not deteriorate, but acquires new properties. And if you grind it and add salt and a little vegetable oil, you get such a seasoning for the meat that it is impossible to forget the dish. This taste is now called fifth or umami.

So the Koreans began to keep garlic in clay pots, which are kept for 60 days in wet straw, self-heating up to + 60 ° C. Now everything is easier: the garlic heads, without peeling, are placed in a special electronic pan. In it, they languish for three weeks at a temperature of about 65-70 degrees with a high level of humidity (in an ordinary rice cooker for the same period, black garlic is also obtained in the “heating” mode).

This process is not even really fermentation. In fact, garlic is caramelized in this way, like onions when languishing: the amino acids and sugar contained in it are broken down, and melanoidin is formed, an almost black polymer substance, which gives the cloves a new taste and color. Garlic that has undergone such processing, as in baking, loses its pungency and pungent odor.
