Does anyone have opnion/ experience on buying using Himlayan pink (or black) salt? Is it worth buying, does it make a difference to the taste of your food? My reason for asking is I am looking for a pepper grinder/mill for some coarse sea salt I have but came across an offer of 1 or 2 grinders with 1kg of either or both salts. Nearly bought it but then thought, would I use it?
