We are told that too much salt in the diet is unhealthy.
Today’s invention is to provide salt pre-dissolved in vinegar for use on the dining table. A water spray, of the kind used on plant leaves, would be filled with vinegar and a small amount of salt added in the factory so as to form a solution of known concentration.
This would allow foods, such as fish and chips, to have only limited quantities of salt applied to them (and in a more uniform way than sprinkling separately).
