At a glance
| Origin | India and across South Asia |
|---|---|
| Type | Specialty salt |
| How it's made | Raw salt is sealed in ceramic jars with charcoal and small amounts of seeds and bark (such as harad, amla and bahera) and fired in a kiln for about 24 hours. The heat turns some of the salt's sulphates into sulphur compounds. |
| Colour and texture | Brown-black lumps that grind to a powder ranging from pink to black-brown. |
| Best for | Chaat masala, chutneys, raita, fruit salads, and vegan dishes that need an “egg” flavour. |
| Swap with | Nothing quite matches its flavour. |
| Smell | Its eggy, sulphurous aroma is expected, not a sign it has gone bad. |

The story
The raw salt traditionally came from Himalayan mines and from the North Indian salt lakes of Sambhar and Didwana. It is used across South Asia, and its smell comes mostly from hydrogen sulphide created in the kiln.
