What is Black Garlic?

Black garlic is simply regular garlic that has been aged under certain humidity and warmth conditions. This “aging” process is what gives the black garlic its dark color.

This reaction not only browns the garlic but also gives it a new flavor: sweet and syrupy with hints of tamarind, balsamic vinegar, fried onions, and seared meat.

The most common way of making black garlic at home is by heating whole garlic bulbs over a span of three weeks.

These garlic bulbs are to be placed inside a rice cooker in a place where there is good ventilation (preferably by the window). You need to peel the garlic skin until the partitions of the cloves are revealed.

When this is done, the whole garlic bulbs must be placed in one layer inside the rice cooker. After closing the lid, you need to press the ‘Keep Warm’ button and leave it for 21 days.

It is essential to note that there are no other ingredients nor preservatives added when making black garlic. The color and flavor of the regular garlic are altered through the process of fermentation.
