Garlic is valued for its medicinal properties and it is also a major ingredient used to flavor our food. However, today, black garlic is becoming increasingly more important.
Black garlic is not as well-known as its white counterpart, but with its unique flavor, vibrant colour and smooth texture, it is gaining popularity. It is believed that it could have twice the antioxidants that are contained in the common white garlic.
What is black garlic?
It is Garlic that has gone through a fermentation process, hence the name "black" garlic. You can then buy bulbs and cloves after this process, which is gaining new devotees daily.
Black garlic is produced by fermentation of the bulbs at temperatures of 65-80°C in an atmosphere of controlled humidity for almost a month. After this, the garlic becomes black.
After fermentation, a process of oxidation for about 45 days takes place to acquire a sweet taste similar to a plum.
The black garlic can be eaten raw or cooked in the same way as fresh garlic. Although garlic is the only component of black garlic, it is likely that the flavor does not resemble anything you have tasted before. Black garlic is full of complex flavors: The initial bite is mild, followed by an explosion of caramel sweetness and a salty finish.
Black Garlic Nutrition
The good news is that it is not only useful for the kitchen, black garlic is also rich in vitamin C, sulfur compounds and other antioxidants and it is estimated that during the process of fermentation, garlic can triple the amount of antioxidants it contains.
Benefits of black garlic
Although more research on the benefits of black garlic is required, it is believed that the process of fermentation results in a "super" garlic, increasing its positive effects on human health.

The fermentation that produces black garlic reduces its strong aroma and flavor, making it more acceptable and attractive to some people. The flavor of black garlic has been compared with a smoky, sweet dried fruit with a touch of salt. Black garlic does not have the same smell as white garlic which is, to many people, considered unpleasant.
