A method of producing a salt composition comprises comminuting a first particulate fraction comprised of sodium chloride crystals having a mean particle size by volume of at least 500 μm, in the presence of a second particulate fraction which is a salt product comprised of particles which contain (a) sodium chloride and (b) an organic material that is a solid at ambient temperature. The particles of the second particulate fraction have a structure comprised of individual crystallites of sodium chloride attached together in the particles of the product wherein at least 95% by volume of the particles of the salt product have a size less than 100 μm and wherein particles of the product comprise hollow particles formed of an outer shell of said crystallites.
