What Is Black Garlic?

Black garlic is simply fresh garlic that has undergone a gradual aging process; it is not a distinct variety of garlic. In this procedure, whole garlic heads are subjected to high humidity and low heat for several weeks. With time, the garlic cloves develop a black color, a soft, chewy texture, and a flavor that is rich, sour, and sweet. It is frequently used as a pizza topping, in salad dressings, and in sauces.

How Black Garlic Is Made

Black garlic is produced primarily through the Maillard reaction, a non-enzymatic browning process. While sometimes referred to as 'fermented,' true microbial fermentation does not occur. Sugars and amino acids undergo a chemical reaction that modifies the flavor and color.

• Process Duration: Typically lasts three to six weeks.

• Required Conditions: A constant humidity of 70–90% and a temperature of 140–194°F.

• Not True Fermentation: Despite being referred to as fermented garlic, microorganisms are not involved.

• Tools Used: You can make homemade black garlic in a slow cooker or rice cooker.

• Changes Inside: The garlic inside becomes darker, with a sticky consistency and deep umami flavor.

How Black Garlic Is Different From Regular Garlic

The distinctions between black garlic and raw or roasted garlic are evident. It has more nuanced flavor nuances and is sweeter and gentler.

• Color: Deep brown to black.

• Taste: Like aged balsamic vinegar or balsamic vinegar, but with licorice and tamarind flavors.
