One of the rarest and most precious of salts, this blue is produced from a single seam running through an ancient salt lake bed in Iran. Its colour is due to an optical illusion, due to the movement of tectonic plates which results in the salt taking on the colour of sylvin, another mineral. In flavour, it has a strong initial saltiness to a subtle lingering aftertaste. Its lovely appearance makes it excellent for a ‘bespoke’ dining table, but bear in mind the colour will fade the more finely it is grated. One excellent and decadent way to use Persian Blue is to use it to coat the glass rim when making a Margarita. Persian Blue is the perfect solution whenever a truly luxury salt is needed!
