Can You Use Sea Salt to Make Ice Cream?

For father’s day this year, I received an ice cream maker. I bought all the necessary ingredients but then realized I had forgotten about salt. All I had in the house was sea salt, so I wondered if it would work in making ice cream. So, I did some research, tried it out, and this is what I learned.

Sea salt and any other type of salt can be used to make ice cream. However, the larger the salt grains, the better. Controlling the temperature and the freezing process is easier when the grains are large. Because of this, rock salt is known to be the best salt to make ice cream.

The rest of this article will go into greater detail about which salt works best to make ice cream. As a bonus, I’ll even talk about how sea salt can be used as a flavoring in your recipe, just in case you wondered.

The Best Salt for Making Ice Cream

Rock salt has generally been seen as the best salt to make ice cream. This is because it has large grains, which makes controlling the temperature and freezing process easier. Rock salt is also cheaper than other types of salt and is sold in bulk. However, ice cream can be made with any kind of salt.

Rock salt is a more economical option than sea salt. You use less rock salt in ice cream than sea salt because rock salt consists of larger grains. Hence, rock salt will take up more room in a cup than sea salt.

Finally, people choose to use rock salt because it adheres to the ice more evenly than other salt types. This means that the entire batch of ice cream will freeze at the same rate.

Why Salt Is Used to Make Ice Cream

It is harder to get ice cream to freeze than water because ice cream consists of sugar and fats. Sugar and fats hinder the ice-creams ability to form ice crystals, which means ice cream freezes at colder temperatures. Because of this, you cannot use ice alone to cool the cream base. The ice cubes would melt before the ice cream mixture gets cold enough.

Salt lowers the melting temperature of ice. So applying salt to ice creates a “salt slushy” that can be packed around the ice cream base. This slushy mess is much colder than solid ice cubes, allowing the ice cream base to cool down, thicken and freeze before the ice fully melts.

The Process of How the Different Salts Are Made

People can obtain salt through these three processes: seawater evaporation, mining, or salt brine creation.


Sea salt forms when bays and ponds evaporate. This evaporating process has been industrialized to yield more sea salt. Companies take ocean water to concentrate pools where the sun and wind act to dry up the pool leaving behind salt crystals.

This is usually done in communities with dry climates and little rainfall. These climates allow time for evaporation to occur.


Rock salt can be found below the earth. Through deep shaft mining, companies can extract rock salt to be crushed with the aid of dynamite. After the crushing process, the rock salt is ready to go out to consumers.

Salt Brine Creation

An artificial salt brine can be created through hydraulic mining. Hydraulic mining is a process where water is pumped below the earth’s surface to dissolve salt in order to make a salt brine. On the earth’s surface, the salt brine evaporates, leaving behind salt.

This process can be used to create table salt.

Making Sea Salt & Ice Cream

While we are on the subject of salt and ice cream, if you are looking for a cold treat with a bit more flavor, then you should try sea-salt ice cream. There are countless recipes online that can show you how to turn sea salt into a delicious frosty treat.

Even characters in the video game Kingdom Hearts can be seen enjoying this tasty treat. The addition of this treat to the virtual world was the brainchild of Kingdom Hearts II director Tetsuya Nomura. He enjoyed sea salt ice cream so much that he wanted to include a depiction of this treat in the game when he was at Disney in Tokyo.

The main ingredients for this sea salt concoction include sea salt, eggs, sugar, milk, heavy whipped cream, and vanilla.

The measurements of these ingredients change from recipe to recipe and depend on the amount of sea salt ice cream you are trying to make. Sometimes instead of regular sugar, people choose to add in light brown sugar. Brown sugar adds a taste of caramel to the recipe.

  1. Mix the eggs and the sugar.
  2. In a separate pot, you boil milk.
  3. Slowly add the milk to the bowl with sugar and egg inside.
  4. The whole mixture returns to the stove and sits on medium heat to form a custard.
  5. Take the mixture comes off the stove. This is when you add the sea salt. Please taste the result to make sure you have enough sea salt.
  6. When finished, you pop the bowl into the fridge.
  7. When cool, mix in your heavy whipped cream and vanilla. You can even add food coloring to give your tasty mixture a unique color.
  8. The mixture can be frozen by following the two-bowl method. In a larger bowl, put ice cubes and sea salt. In the smaller bowl, the ice cream base. Place the smaller bowl in the larger bowl to keep the ice-cream mix cold while using a mixer to stir in the whipped cream and vanilla (mix for 10-15 minutes).
  9. Finally, place your ice cream in a container in the freezer.

If using an ice cream machine make, you can follow their instructions on freezing.

Final Thoughts

There is nothing better than homemade ice cream on a hot day. So, stock up on some rock salt so that you are ready to go when the mood strikes you and your family.
