Oh I want to try it out but I'm kind of scare by any salt recipe from the new world. It seems that USA' and Canada's standard size of cristal salt is very diffdrent from the french one, living many of my dishes from there way over salted. I guess if we're talking about melted salt and brine saturation it could be fine but I'm still scared.
Can I use any potatoes or do I need something starchy/tender/...?
