Coarse salt
Salt in large crystals — a basic, preserving substance that the food cannot do without.
Coarse salt in a dream is the dream's image of a basic substance that the food, and the body, cannot do without. Salt is not flavour added on top; salt is what makes the existing flavour available. The dream brings coarse salt when something in your life — a friendship, a routine, a discipline — is the simple, unromantic input that is making the rest of the life taste like itself. Salt used in the right measure is the dream telling you the basic is being honoured. Salt used too heavily, ruining the dish, is the dream noting that the basic has been over-applied, and what is essential in small quantities has become destructive in large ones.
