What is the difference between rock salt and ice cream salt?

By Sara Iranidoost, On 2nd March 2021, Under Food and Drink
Now that that nerdy background information is out of my system, I can actually answer the question: "ice cream salt" (usually called "rock salt") is exactly the same chemical as table salt, but its crystals are large and coarse instead of small and fine.

Thereof, can you use regular salt instead of rock salt for ice cream?

Both rock and canning salts can be substituted with table salt. When table salt is used in place of rock salt be careful of the amount as too much table salt can cause the ice cream to freeze to fast and become "crusty".

Also, can you eat rock salt for ice cream?

Rock Salt For Making Ice Cream.
This will result in more rapid cooling at lower temperatures than what's possible with ice alone. *Morton Ice Cream Salt is NOT intended for consumption.

Is rock salt the same as kosher salt?

Kosher salt or koshering salt (outside the US called kitchen salt, cooking salt, flake salt, rock salt or kashering salt) is coarse edible salt without common additives such as iodine. Used in cooking and not at the table, it consists mainly of sodium chloride and may include anti-caking agents.

Is Rock Salt OK to eat?

Ice-melting chemicals commonly contain sodium chloride or rock salt, calcium chloride, potassium chloride, magnesium chloride, and/or urea, also known as carbonyl diamide. If swallowed, they can be irritating and cause stomach distress. On the skin or paws, they can cause irritation and dryness.
Fill the large ziploc halfway with ice cubes and add 1/4-1/2 cup of salt. You can use rock salt (works best) or table salt (still works well). In the small bag, put 1.5 cups of your favorite milk, reduced fat milk, or heavy cream. Add two tablespoons of sugar for every 1.5 cups of milk (or to taste).
Dangers to Humans
Just as it is the case with pets, rock salt causes burns when it comes into contact with the skin. It similarly causes respiratory tract irritation when inhaled. Repeated exposure may be fatal since it corrodes major components of the respiratory tract, but this is extremely rare.
Rock salt dust can irritate your mouth, throat, stomach, and intestines if accidentally inhaled, and it can lead to severe vomiting/diarrhea.
Adding salt lowers the freezing temperature of the water and for wintery roads, it means that the water won't freeze as easily. For our ice cream, it allows the temperature of the mixture around the ice cream to get colder. Rock salt isn't processed as much as table salt, and is much chunkier.

Rock salt is used to remove ice and snow from concrete surfaces during winter. Many American households use it to melt ice. Rock salt can pose hazards to human beings, pets, and even property. The risk is even greater when the compound is used in large quantities.
Unlike most table salt, sendha namak is not fortified with iodine. Thus, completely replacing table salt with sendha namak may raise your risk of iodine deficiency. You should likewise be sure to consume rock salt in moderation.
Salt doesn't contain water, so it doesn't support microbial growth, meaning it won't spoil. It's not because of the salt, though. It's because of the additives. Iodine and anti-caking agents degrade over time, reducing the shelf life of the salt to about five years.
To answer your question Morton® Ice Cream Salt is not intended for food use. Other trace residues could be present from the blasting material used to mine the salt. It is not necessary to use food grade rock salt for making ice cream as the salt and/or brine should not come in direct contact with the ice cream.
Halite ( /ˈhæla?t/ or /ˈhe?la?t/), commonly known as rock salt, is a type of salt, the mineral (natural) form of sodium chloride (Na Cl). Halite forms isometric crystals.
Ice-melting chemicals commonly contain sodium chloride or rock salt, calcium chloride, potassium chloride, magnesium chloride, and/or urea, also known as carbonyl diamide. If swallowed, they can be irritating and cause stomach distress. On the skin or paws, they can cause irritation and dryness.
Your best bet: Kosher salt
Kosher salt has the clean flavor of salt without the bitterness that some people associate with iodized salt. It also has larger crystals than table salt, which is the characteristic that makes it an excellent rock salt substitute.
Adding salt lowers the freezing temperature of the water and for wintery roads, it means that the water won't freeze as easily. For our ice cream, it allows the temperature of the mixture around the ice cream to get colder. Rock salt isn't processed as much as table salt, and is much chunkier.
If you've decided that using an alternative to rock salt is the best thing for you, these are your 5 best options:
  1. Sand.
  2. Stone Grits.
  3. Calcium Chloride.
  4. Magnesium Chloride.
  5. Calcium Magnesium Acetate.

Grow Rock Salt Crystals
  1. Heat the water to a rolling boil. Very hot tap water is not hot enough because salt solubility depends on temperature.
  2. Stir in salt until no more will dissolve.
  3. If desired, add a couple of drops of food coloring.
  4. Pour the solution into a clean container.
  5. Let the salt crystals grow.
Rock salt is used to cause the freezing point of ice to drop which draws the heat out of ice cream causing it to freeze and the ice on roads to melt. Canning salt is used mostly as a preservative especially when pickling and to add flavor.
Rock Salt - Halite more commonly known as Rock salt is a mineral formed from sodium chloride. Epsom Salt - Epsom salt, named for a bitter saline spring at Epsom in Surrey, England, is not actually salt but a naturally occurring pure mineral compound of magnesium and sulfate.
The salt lowers the temperature at which water freezes, so with salt ice will melt even when the temperature is below the normal freezing point of water. Technically, the temperature that the salt lowers is called the freezing point.
It is the same chemical composition as table salt. Sodium Chloride. But the salt you purchase for making ice cream or melting the ice on your driveway or sidewalk should not be eaten. It may have several impurities and is not intended for human consumption.
