Difference Between Black Salt and Rock Salt

Black salt and rock salt are two different types of common salt that are found all over the world and have some distinct characteristics.

Consuming too much salt is never good for your health, but these salts do have some properties which might be beneficial for humans. Black salt and rock salt, both have their advantages as well as disadvantages.

Black Salt vs Rock Salt

The difference between black salt and rock salt is that the only purpose of black salt is for consumption, and sometimes other health benefits, whereas, rock salt is used for several different reasons. Even though there are a lot of similarities found between the two, some distinct traits always separate them.

Black salt also recognized as Himalayan black salt, kala namak, or Indian black salt, is a basaltic lava salt produced in the Himalayan range.

A black salt is a form of rock salt that is used in South Asia as a briny and pungent-smelling flavoring. It is a popular ingredient that is commonly recognized as bit laban in Bangladesh. It is used to enhance the flavor of food.

Sendha namak, or rock salt, is used in Ayurvedic medicine for centuries. While the study on most of these advantages is limited, rock salts provide essential minerals and may aid in the treatment of sinus infections and reduced salt levels.

You cannot use it as a flavoring agent unless it is labeled as edible. Rock salt contains contaminants, primarily minerals, that are eliminated from the salt we utilize in our daily cooking.

What is Black Salt?

The color of Indian black salt varies; some might even not be black at all. It comes in a variety of colors ranging from brownish pink to murky violet and is accessible in whole clumps or powdered shapes.

If you go to a culinary store, you will notice that there are several types of black salt. 

You should be aware of two other kinds of black salt: black ritual salt as well as black lava salt. Such black salts are not the same as the umami-rich, flavor-enhancing Himalayan black salt and can be used for entirely different reasons.

Black salt is utilized as a food additive in several Indian and Asian recipes. 

Indian kala namak is used in a variety of dishes, including pickles, side dishes, chutneys, raitas, as well as fruit appetizers. Black salt contains less sodium than regular table salt.

While sodium is an important component of a healthful diet and plays an important role in our cells, most Westerners consume far too much sodium via packaged foods, which leads to high pulse rates and other troubles. 

Black salt may play a minor role in tackling this issue.

Because black salt is not oxidized like regular table salt, you would then require iodine from fresh fish or other alternatives to avert goiters as well as other health problems associated with iodine inadequacies.

What is Rock Salt?

Rock salt, also recognized as halite, is a sort of salt that forms from the remains of primitive bodies of water in the bumpy strands of the Earth’s mantle.

The majority of the salt we utilize in preparing food, both table salt as well as Kosher salt, is produced by swamping buried salt deposits with surface water, retrieving the water, and then dissipating it to exit behind pure rock salt. 

Hydrolyzing the salt from seawater yields a smaller percentage known as sea salt. Rock salt, on the other hand, is extracted directly from the earth, retaining its cube-shaped crystalline phase.

Some types of food-grade rock salt could be used to make brines, as well as for other purposes. Creating ice cream is among the most prevalent culinary applications for rock salt. 

Ice cream is created by incorporating milk, cream, sweetener, and other flavoring additives, then chilling it using a rousing and cool technique.

Aside from culinary applications, you could also insert rock salt into the ice in your cooling system to help it stay solid longer by reducing the thermal properties. 

Another application is as a water stabilizer. Of course, rock salt is frequently used to dissolve ice on streets and sidewalks.

Rock salt can be purchased in cartons or bags varying from 4 pounds to 50 pounds at equipment stores and supermarket stores. As long as you maintain it dry, rock salt could be stashed endlessly.
