About Persian Blue Salt
Persian blue salt is one of the rarest salts on earth. It is found only in a few salt mountains in Iran's Semnan province. The blue coloration occurs when the halite crystal lattice is compressed under extreme geological pressure over millions of years, causing a structural change called sylvinite that refracts light to appear blue. Annual production is only a few tons.
Best for: Finishing seafood, Foie gras, Truffle dishes, Desserts, Specialty cocktails.

Salt production in Taiwan dates back to 1665 when Zheng Chenggong (Koxinga) established salt fields in the Tainan area to supply his military forces and civilian population. The industry expanded through Dutch and Qing dynasty periods. At its peak in the 20th century, Taiwan had over 4,000 hectares of salt fields. Today, most commercial salt production has ended but traditional methods are maintained in cultural heritage areas like the Jingzaijiao Tile-Paved Salt Fields, where salt is still harvested using ancient wooden tools on tile-paved pans.
