Pickle crisp is CaCl2
Pickle crisp is CaCl, it is a replacement for pickling lime.http://www.culinate.com/author/Linda_Ziedrich/blog/the_scoop_on_pickle_crispNow that I know that, I'm adding some to my pickle recipes. Thanks for the dosage info Denny.
The calcium chloride really did the trick. My pickles still have a few days to go because they are not sour enough but these are the most firm and crisp pickles I have ever had.
