How much rock salt is needed for homemade ice cream?

To make and pack up to 4 quarts of ice cream, you will need about 15 pounds of crushed ice and either 4 cups of table salt or 6 cups of rock salt. Refer to the table below for more information. Wash the beater (often referred to as the "dasher"), top and cream can well before using.
A.

Is there a difference between rock salt and water softener salt?

Sidewalk salt is also known as rock salt. It's unprocessed sodium chloride taken directly from the ground. Softener salt doesn't melt ice any faster than sidewalk salt. But using sidewalk salt in a water softener will cause big problems.
  • Can I use a salt block in my water softener?

    No, to soften water, you need a water softener. The salt used in the brine tank of a water softener does not directly soften the water, but is used to regenerate the resin beads in your water softener. These actually soften the water from your well by removing the hard water ions, calcium, magnesium and iron.
  • Can you mix salt and potassium in a water softener?

    Note: No harm will be done to the softener should the consumer mix salt and potassium chloride. The water softener does not know if there is salt or potassium in the brine tank. So the amount of brine that the softener makes with either salt or potassium is the same for any given regeneration cycle.
  • Can you drink potassium softened water?

    An additional benefit of potassium chloride is the impact on sodium in drinking water. Studies have found that softening water with potassium chloride does not add sodium to drinking water, and will also remove up to 90 percent of the existing sodium from the water.
B.

Why do you put rock salt in an ice cream maker?

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.
  • What will happen if you put salt on ice?

    The ice cube without salt melts because the air around it is warmer than 32 degrees F. The salted cube melts faster. When you add salt it dissolves into the water of the ice cube. Salt water freezes at a lower temperature than the 32 degrees F at which freshwater freezes. This makes the ice with salt on it melt faster.
  • How long do you have to shake your homemade ice cream?

    Shake and massage the bag for about 5 minutes or until mixture thickens into ice cream. Add more salt and ice to the outer bag if ice cream hasn't formed after 10 minutes of continuous motion.
  • Why do you get thirsty when you eat ice cream?

    Eating ice cream, in a sense, makes your body think it is dehydrated, and in a sense, I suppose it is. This is one of the reasons that diabetics are thirsty all the time. Diabetes causes high blood glucose, and that increased concentration of blood solutes makes the diabetic feel thirsty. In short: It's the salt.
