Rock salt

  • 5

I need to find rock salt for making ice cream. My 6 year old girl has one of those kiddy ice cream maker and she'd love to make some. I'm not sure exactly what rock salt looks like or where to buy it. Could it be called something else?

Where in Toronto would I find rock salt?

Thanks.

  1. Here in the US, I get it at a hardware store- it's the same stuff you'd use on ice.

    1. You definitely do NOT want to use the winter-grade stuff. I've picked it up at bigger GTA Loblaws and Highland Farms.

        is there any reason why not? or will it damage the machine?

        it's not like the salt is touching the food

          Why is that? If it is pure salt, and chunky, it will make ice cream.

        2. You should be able to use corse salt. Check Bulk Barn,

          1. The most likely source is a hardware store or, possibly, a Crappy Tire. However, coarse or kosher salt should work. The stuff they sell as "rock salt", if pure, typically has bigger crystals. It's easier to use and possibly more efficient. However, the crystals might not even fit into a "kiddy" machine.

            Remember that you are using salt to lower the temperature of your ice. Some industrial ice melters will turn your ice into hot water in a few minutes.

            Be careful about what you find at places like Crappy Tire. They may have pure salt, but much of what they sell contains substances that you don't want anywhere near food.
