@chromedomeI do use coarse salt in my brining, in fact it's the only thing I use. I was just worried about mixing it with a nitrite powder. When we first moved down here, I was delighted to find a coarse salt in a package in the grocery store. I came home and set up a batch of dill pickles, which we couldn't get down here either. Within 2 days I had the most vile mess that you've ever smelled. I read the label on the package that I had bought and it was called Sal Inglaterra (English salt). When I was finally smart enough to read the dictionary I found out that I had bought Epsom salts. Not recommended for dill pickles!
BYT, it is supposed to reach 85 degrees here this afternoon.
