One glass was empty (except for air, of course). Salt is hygroscopic and draws moisture out of the herbs at the same time some of the salt will dissolve. Our hope is to provide a resource where you can find all things Sensory Dough in one place. The salt molecules from higher concentration areas move to the side of lower concentration, drawing out water and thus dehydrating the meat. So how does salt preserve food?
