After conventional table salt is mined, it’s bleached and combined with anti-caking agents. This process destroys most of the trace minerals salt normally contains, like calcium, magnesium, phosphate and zinc. And stripped away with those nutritive minerals go a whole panorama of subtle flavors — the kind that add exceptional character to food. Fortunately, full-bodied finishing salts, like these from Artisan Salt Company, maintain their full range of colorful personality and potential. About $15 at natural markets or www.artisansalt.com.
