Heuk-maneul — Black Garlic

Black garlic, heuk-maneul (흑마늘), is the whole bulb of common garlic aged until the cloves turn black, and it is produced in Korea and elsewhere in East Asia. It reached Western kitchens in the early 2000s, carried largely by Japanese and Korean food producers. The darkening comes from the Maillard reaction and enzymatic browning sustained over weeks at low heat, and it is not a fermentation, though it is often labelled as one.

Black garlic is the whole bulb of common garlic, Allium sativum, aged intact and in its skin until the cloves turn soft, glossy and black. The bulbs are held at roughly 60–70°C (140–158°F) and high humidity, about 80–90%, for some three to four weeks. The Maillard reaction and enzymatic browning change the raw, pungent cloves into a yielding, jam-like flesh. Its flavour sits between tamarind, molasses and aged balsamic vinegar, with none of the raw heat of fresh garlic.

Black garlic provides sweetness, depth, and complexity without any of the sharp heat of raw garlic. It dissolves into sauces, can be pureed into aioli, sliced onto pizza, or eaten as a condiment. Its flavour reads as something between tamarind and aged balsamic — it belongs in any context requiring sweet-savoury depth without sharpness.
