Frost salt, known as Givre de Sel, is a rare salt from the White Desert region of Egypt, particularly between the Bahariya Oasis and the city of Qasr el Farafra. Its fine, airy crystals visually resemble frost or snowflakes. This unique salt is formed by the evaporation of water in underground salt deposits that were created by a primeval sea approximately 70 million years ago.
The salt is traditionally harvested by Bedouins who know the exact location of the deposits. They remove the sand, expose the salt layers, and collect the delicate crystals by hand. This elaborate method and its rarity make frost salt a true delicacy.
