There is an intermittent conversation between the various branches of our family about what constitutes enough/too much salt – there is a balance to be struck somewhere, I suppose, but the unspoken assumption is that we do need some salt in our daily diet. This past winter we’ve needed rather more than average for frosty roads and paths. (Apparently an added ingredient, used by some councils and agencies, is molasses to make sure it doesn’t get washed or blown away too quickly). Time was when people were paid their salary in salt because it was both a useful and a valuable commodity. You don’t hear much about a salt standard these days – not sure if salt would work as an alternative to dollars, euros and pounds.
