Just curious to see if anyone in the group has been able to find the Salt NaCl for class?

I can buy salt in the grocery store that doesn't have iodine. Can I use Kosher or canning salt?

I imagine a non food grade might be less expensive, where would you find it?

Thanks.

Mary

 

P.S. What's several pounds? 7, 10, 20?

I got a large (25#) bag of plain salt at Costco for $3.95.  I had heard that canning or pickling salt is fine.  Kosher too, and I would expect that Karren will have us measure by weight, but if you have a need to measure by quantity, the pburch site gives a simple conversion for a couple different brands of kosher salt:

DancingFish -

Is that without iodine? What section of Costco did you locate this? Thanks.

Yes, it's plain salt, no iodine.  It was one row over from the 2 gallon combo pack of vinegar that I also picked up ;).  Near the baking stuff where all the flours and sugars are.

Here's what it looks like at Sam's:

Morton calls their uniodized salt "plain salt" or just "table salt".  But they also do produce the 25 lb bags in iodized salt (which is marked as such), so make sure you get the right one.   I only saw the plain (table) salt at my Costco.

Here's how the bag is marked if it's iodized:

All those sources sound fine, including the ebay one Mary sent me .  My email program won't send Mary emails today, stange.  Just read the labels- no additives in either salt or soda ash.
