Just as the Himalayan salt has a color scale that goes in pink / orange tones due to its content of iron and manganese, so the Persian blue salt gets its unique color from potassium, among other things. In addition to the effect of potassium, the color tone is also created by natural compression of the salt’s structure over time. The beautiful effect can be compared to blue glacier ice where the molecules have been compressed to a level where the light begins to be reflected in a different way.
Persian blue salt is one of the most unusual salts in the world. It is a fossilized salt found in the mines of the ancient Persian Empire, now Iran, in the northern part of the country. The salt was already there millions of years ago, during the same era as the dinosaurs
The salt is described with a rich salty taste, but the connoisseurs also say they taste a ton of citrus. The whole salt stone is most easily used with the help of a grater. Persian blue salt goes well with most dishes, but is perhaps especially appreciated for seafood or fresh vegetables.
In addition to seasoning, the salt stone is decorative with its sapphire blue color.
