Black Salt vs. Rock Salt: What's the Difference?

By Janet White || Published on December 12, 2023
Black salt, typically from South Asia, has a pungent, sulfurous aroma and is used in Ayurveda, while rock salt, often pink or colorless, is a larger crystal salt used in cooking and de-icing.

Key Differences

Black salt, known as Kala Namak in South Asia, is a type of rock salt with a distinctive sulfurous smell and a tangy taste, often used in vegan cooking to mimic the flavor of eggs. Rock salt, on the other hand, refers to the large crystal salt that is mined from salt deposits, with a more neutral taste and is used in various culinary and industrial applications.
The color of black salt ranges from dark brown to black, and it is often used in small quantities due to its strong flavor. Rock salt typically appears in a more natural, unrefined form, ranging from colorless to pink, and is used both for cooking and as a de-icing agent during winter in many countries.
In traditional medicine like Ayurveda, black salt is prized for its perceived digestive and therapeutic benefits. Conversely, rock salt is valued for its pure, unprocessed state and mineral content, making it a popular choice in gourmet cooking and therapeutic practices like salt therapy.
The production process of black salt involves the heating of Himalayan pink salt, mixed with Indian spices and herbs, which contributes to its unique flavor and aroma. Rock salt is extracted directly from underground salt deposits or salt mines, retaining its natural crystal structure and mineral composition.
Black salt is a common ingredient in South Asian cuisine, particularly in snacks, chaats, and salads for its unique flavor. Rock salt finds its use in various culinary traditions worldwide, often as a finishing salt for its texture and as a seasoning in larger dishes.
