What Are Key Differences Between Kosher Salt and Sea Salt?

Differences between Kosher and Sea Salt

Aside from table salt, kosher and sea salt are two of the most popular ingredients used for cooking, baking, and other purposes. But what’s the difference?

While there are many similarities, there are a few differences between kosher and sea salt relevant to their shape, size, origins, and price. Keep reading to learn more about the similarities and differences between kosher and sea salt along with their unique benefits.

What is Kosher Salt?

Kosher salt has large, coarse grains that come from salt deposits. Kosher salt was originally used to get blood out of meat and make it kosher. 

Kosher salt is made of sodium chloride and does not contain additives or iodine like table salt. While iodine can be helpful for thyroid health, it can have a metallic kind of taste. Some people are turned off by table salt for this reason. Since it is not iodized, Kosher salt is pure and doesn’t include the bitter flavor of iodine.

Kosher salt is typically sold in either coarse or fine textures. There are two main brands that sell kosher salt: Mortons and Diamond Crystal.

Kosher salt is often used in the process of cooking. It can’t be directly substituted for table salt because it is lighter. However, you can use a conversion to determine what amount of kosher salt can be a substitute for table salt. Once this is done, kosher salt can be used while making dishes or as a finishing touch. Aside from cooking, kosher salt can also be used in cleaning or to keep food fresh.                 

What is Sea Salt?

Sea salt has more fine grains and comes from evaporating ocean water. It has uneven flakes and less consistency in shape, size, and color. For this reason, sea salt is available to buy in different sizes.

Like kosher salt, sea salt is not iodized. However, there is limited processing of sea salt so there can be small amounts of minerals found in this type of salt. For example, minerals like potassium can be found in sea salt.

Sea salt is commonly used as a finishing touch in cooking and baking. It is more expensive than kosher salt, so while you can use sea salt as an alternative to kosher in recipes, this is usually avoided because of the price. Sea salt is also used in body scrubs and bath products because it is said to relieve stress and relax your muscles.

What is the Difference Between Sea Salt and Kosher Salt?

There are a lot of similarities between sea salt and kosher salt. They’re both made up of sodium chloride with no iodine and limited additives. The main differences lie in their origins, prices, and personal preferences.

Sea salt is a result of evaporating ocean water while kosher salt is mined from salt deposits. Sea salt costs more than kosher salt, which can cause people to use it sparingly. For instance, sea salt can cost more than double what kosher salt costs. For this reason, in the context of cooking, sea salt is more likely to be used as a finishing touch or garnish rather than in recipes.

Conversion Ratios for Kosher and Sea Salt

Sea and kosher salt can also require different amounts by volume to get the same amount of sodium. The kosher and sea salt conversion ratio is about 1 teaspoon: ¾ teaspoon. In other words, if you were to use sea salt as a substitute for kosher salt, you would only need to use ¾ teaspoon of sea salt to get the same amount of sodium in 1 teaspoon of kosher salt. 

On the other hand, if you were to use kosher salt as an alternative to sea salt, you would need to use 1 teaspoon of kosher salt for every ¾ teaspoon of sea salt. For flaky sea salt, it is a 1:1 ratio. Thus, depending on the kind of sea salt you use, you get more sodium in a lesser amount of sea salt than kosher salt.

Different people may also prefer different kinds of salt. There are slightly different sizes and textures of each kind, leading consumers to prefer one over the other based on taste. Consumers may also have a preference based on what they need to use salt for. Kosher salt can be easier to control if it’s important that salt is distributed evenly across a dish. Meanwhile, sea salt has a light and elegant touch to bakery items and other meals.

Kosher vs Sea Salt: Which is Healthier?

Some people believe that sea salt is healthier than other kinds of salt. This often comes from the belief that the extra minerals in sea salt add to its health benefits. However, scientists say that there is no significant difference in healthiness between kosher salt, sea salt, and table salt. There is a similar amount of sodium in all three kinds of salt, so the kind of salt you use is mostly dependent on what you’re using the salt for and personal preference.

Which Salt is Your Favorite?

The bottom line is that the salt you choose to use is up to you. There are no significant differences in the impact of different kinds of salt on your health. As a general rule of thumb, try to consume salt in moderation

Also, keep these differences in mind:

  • Kosher salt has larger coarse grains, while sea salt is fine
  • Neither kosher nor sea salt contain additives or iodine, but sea salt can contain small amounts of minerals
  • Sea salt is usually more expensive than kosher salt
  • Sea salt is more often used as a finishing touch in cooking or baking, while kosher salt is more often used in recipes
  • There can be different sodium by volume between salts. Thus, if you are substituting one kind of salt for another, make sure that you make a conversion if necessary.
  • There are no major differences in the healthiness of each kind of salt.
