Originated in Asia, black garlic has become an energizing superfood that gained a lot of attention worldwide. Not only does it taste good raw due to its sweet taste, but it also has a lot of health benefits.

Black Garlic

Black Garlic

Black garlic is an aged food made from regular white garlic. It has been aged in a controlled heat and humid condition, ideally at 70°C to 80°C, for about 11 days to 3 weeks time. As the garlics go through a steady heating process for a certain period of time, the color of the cloves will gradually turn darker and become inky black at the end of the process. This heating process causes a Maillard reaction on the garlics and changes the overall flavor. Maillard reaction causes food to char and turns brown. You can find an example of Maillard reaction on all kinds of food like roast meat, toast, beer, caramel, and others.

In Japan, black garlic was developed for the first time in Mie Prefecture in 2004. Later in 2006, Aomori Prefecture that produces about 70% of the total garlic production in Japan, started to develop black garlic as well and became one of Japan’s prefectures that is famous for black garlic production.


What Does It Taste Like?

Black Garlic Taste

Black garlic has a soft chewy texture and a sweet taste. The taste is said to be similar to dates or prunes with a slight hint of umami. That’s why black garlic is tastier to eat raw than the white counterpart. The sweet taste and soft texture of black garlic may come as a surprise for some people as some thought that black garlic is a natural variant of garlic, therefore thinking it has a similar taste to garlic. In reality, black garlic is not something you can grow, it’s an aged product of raw white garlic.

Different from raw garlic, black garlic doesn’t have that much of a pungent smell. Even though the garlics will release an unpleasant smell during the aging process, the finished product will have a more subtle aroma to it. You don’t have to worry about garlic breath after eating black garlic because the aging process will remove garlic odor by eliminating the sulfur compounds.

Eating a lot of regular garlic raw may cause discomfort in your stomach. This is probably caused by allicin, an antimicrobial component in garlic that has a sterilization effect on the guts.
