Black Garlic: Maillard Through Extended Low Heat

Black garlic originated in Korea (heukmaul) and has been produced in East Asia for centuries, though it entered the Western restaurant world in the early 2000s through Japanese and Korean food producers. Noma documented the production process precisely, demystifying what had previously been considered a proprietary transformation. The chemistry is Maillard reaction and enzymatic browning sustained over weeks at low temperature — not fermentation, despite frequent mislabelling.

Whole garlic heads held at 60–70°C and 80–90% humidity for 3–4 weeks, during which the Maillard reaction and enzymatic browning transform the raw pungent cloves into soft, black, intensely sweet and complex bulbs with flavours of tamarind, molasses, balsamic vinegar, and dark fruit — 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.
