My wife had about a 25 year old box of Sour Salt. It is now finished and we can not find a new box or bottle. We tried Superstore in NE Calgary and Safeway in Red Deer.
I have done a Google Search and Sour Salt is also known as Citric Salt. It is used in pickling and what my wife uses it for is to preserve the color when cooking beets. With an excellent crop this year I can see us using it for sure?
We did see Kosher Salt but neither Sour nor Citric Salt.
Any guesses where we can get it?
