What is black garlic

introducing kuromaru

Black garlic is a type of caramelized garlic (a Maillard reaction, not fermentation) first used as a food ingredient in Asian cuisine. It is made by heating whole bulbs of garlic (Allium sativum) over the course of several weeks, a process that results in black cloves. The taste is sweet and syrupy with hints of balsamic vinegar[1] or tamarind.[2] Black garlic's popularity has spread to the United States as it has become a sought-after ingredient used in high-end cuisine.

The process of producing black garlic is sometimes incorrectly referred to as fermentation, but it does not in fact involve microbial action.[3]
