Two types of salts can be used in food for different purposes. These are sea salt and rock salt.

Both have a unique combination of essential minerals for the body.

Sea Salt vs Rock Salt

The difference between sea salt and rock salt is that sea salt is obtained through evaporation Of the ocean water. On the other hand, rock salt is collected from the ocean, it is already in a consumable form.

Sea Salt vs Rock Salt

Sea salt is obtained from various seas around the world. It is responsible for adding a pinch of saltiness to the food we eat.

Seawater is allowed to evaporate and leave tiny grains behind. These grains later form rock salt.

Rock salt is mainly found in different bodies of water. It is usually gathered from the world’s oceans.

Salt rocks are formed near the oceans due to a high concentration of minerals. It occurs in the form of solid rocks.

What is Sea Salt?

Sea salt is an important ingredient in the food we eat. It is found in tiny bottles on the dining table of every house.

It is made by evaporating seawater and allowing it to crystallize into tiny flakes. Earlier, the method used for obtaining sea salt was quite complicated.

Now, with improving technologies, the process has simpler.

A lot of people are shifting towards using sea salt instead of table salt. One of the major reasons for this outcome is the increased amount of minerals.

Table salt is heavily ground which causes a lot of minerals to wear out. The minerals obtained from sea salt are in adequate quantities and help in maintaining the overall health of the body.

It is often speculated that sea salt can help in maintaining normal blood pressure and hydration levels in the body. This is caused by the proper amounts of sodium which is responsible for maintaining ionic balance.

It can be sprinkled onto roasted foods for enhanced taste. Salt is also known to bring out the hidden flavours in desserts like cupcakes and cookies.

What is Rock Salt?

Rock salt or Halite is obtained by mining underground rocks. It has a higher concentration of sodium chloride and undetectable quantities of other minerals.

The crystal particles of the salt can we be a hassle to dissolve in food. It is found in less abundance as compared to sea salt because mines cannot be found everywhere.

It is generally found in the form of large crystals which are non-uniform in shape and size. It is said to have a large number of impurities and is therefore found in hues of grey.

Apart from using foods, it can also be used for industrial purposes. For instance, in countries where snowfall is a constant problem, rock salt comes as a saviour.

This is because it can effectively melt ice without wasting much time. It has a very strong flavor and is used in very small quantities.

It can out an enhanced flavor in various dishes. For instance, Himalayan rock salt is considered as one of the most healthy options for food.

  1. Sea Salt as the name suggests is octane from the sea by evaporating the water. Rock salt is obtained by solidified rocks form over the years due to mineral deposits.
  2. Sea salt has a combination of a variety of minerals while rocksalt mainly has sodium and chlorine. Different minerals can also be added to sea salt for enhanced quality.
  3. Sea salt is available in different colours ranging from pink to green. Rock salt appears grey in color.
