How to Grow Black Garlic at Home

Last updated on October 23rd, 2023 at 08:19 pm

Today I want to talk about black garlic. A new type of garlic, which is causing a furor in the kitchens lately. They are originally from Japan and widely consumed in Korea and the USA. In Spain it has been known for a few years, and already has multiple uses in our gastronomy. Besides it has very good health properties.

Black garlic, unlike what many people think, is not a new cultivar or variety of garlic; it is obtained through a long fermentation process with low temperature, from common garlic.

How to grow homemade black garlic

To obtain it you have to follow these steps:

It is necessary to start from one or several heads of common or purple garlic (depending on how many we want to obtain); which can be from your own garden or purchased, if you want to know how to grow garlic here we explain it. If you opt for this last option, the best thing is that the garlic is not excessively dry.
Next, the first layer of skin must be removed, taking care that the cloves are still attached.
Place the head of garlic in a completely airtight container with some humidity, such as a glass jar. Another option is to vacuum pack them.
Black garlic needs to ferment at more than 40 degrees Celsius, so to do it at home, as Nuria explained in the comments:

 You can use a yogurt maker, an electric rice cooker or any other appliance that can house garlic heads inside at a constant temperature of between 40 and 50 degrees. A higher temperature accelerates the process, but can dry out or burn them if the humidity is not well controlled.

Once this period has passed, it is taken out and left to dry or “ripen” for about 7 days.
Now you will have your black garlic ready to eat.

Characteristics of black garlic

The most outstanding physical or external characteristics (as can be seen in the photo) of black garlic are:

  • The smell, which is very pleasant fruity and similar to that of balsamic vinegar, which, despite having undergone a fermentation process, does not smell of putrefaction.
  • The texture is light, very tender and unctuous.
  • The flavor it has is intense, sweet and with a slight acid touch; to some people it reminds them of licorice. It can be said to have a somewhat balsamic flavor.
  • The color turns to a pale brown.
  • It decreases the volume of the black garlic clove quite a bit.
