Why didn’t they salt it instead?
Salt was a scarce and treasured commodity, virtually a luxury, in many primitive societies. Battles were fought. Salt mines are unequally distributed around the world. I do not know of any in Scandinavia (land of my ancestors), although there could be some. I “think” native salt deposits are unlikely to be found in igneous bedrocks. Could be mistaken.
