# Black garlic

Black garlic is a type of aged garlic that is colored deep brownish-black. The process is of East Asian origin. It is made by placing garlic (Allium sativum) in a warm, moist, controlled environment over the course of several weeks, a process that produces black cloves. Black garlic is used in a wide variety of culinary applications.

## Production

Black garlic is produced when heads of garlic or separated cloves are aged in an environment of controlled humidity (80 to 90%) at temperatures ranging from 60 to 90 °C (140 to 190 °F) for 15 to 90 days (typically 85% humidity at 70 °C for 40 days). No additives or preservatives are used and there is no burning of the garlic, with the dark color arising from a long-term, low temperature Maillard reaction. The cloves turn black and develop a sticky date-like texture.
Bacterial endophytes capable of fermentation and with strong heat resistance have been identified in common garlic and black garlic. These may have relevance in black garlic production.
Black garlic is different from black garlic oil (māyu) which is raw garlic cooked in oil on a stove.

## Flavor profile

In black garlic, the distinct pungency of fresh garlic is softened such that it almost or entirely disappears, and the garlic develops notes of licorice, tamarind and molasses. Its flavor is dependent on that of the fresh garlic that was used to make it. Garlic with a higher sugar content produces a milder, more caramel-like flavor, whereas garlic with a low sugar content produces a sharper, somewhat more acidic flavor. Burnt flavors may also be present if the garlic was heated for too long at too high a temperature or not long enough: during heating, the garlic turns black in color well before the full extent of its sweetness is able to develop.

## Culinary uses

As a health and nutritional supplement, black garlic can be used alone, on bread, with cheese, red wine or dark chocolate, in soups or sauces, with meat or fish, crushed into mayonnaise as salad dressing, added to a vinaigrette, or with a vegetable dish. The cloves may also be crushed.

## In popular culture

It gained USA television attention when it was used in battle redfish on Iron Chef America, episode 11, season 7 (on Food Network), and in an episode of Top Chef New York (on Bravo), where it was added to a sauce accompanying monkfish, tilefish, risotto or chicken.
In the United Kingdom, where it made its TV debut on the BBC's Something for the Weekend cooking and lifestyle program in February 2009, farmer Mark Botwright, owner of the South West Garlic Farm, claimed to have developed a process for preserving garlic after finding a 4000-year-old Korean recipe for "black garlic".
In season 5, episode 5, of the animated television show Bob's Burgers ("Best Burger"), the main character, Bob, enters a cooking contest and plans to make a burger using black garlic as the special ingredient.
