Sea salt powder is made by evaporating seawater to remove the water and leaving behind the salt crystals. The crystals can be ground into a fine powder and used as a seasoning. Pink Himalayan salt is a specific type of sea salt that is mined in the Khewra Salt Mine in Pakistan. It is said to be purer than regular table salt and contains trace amounts of minerals such as calcium, iron, and zinc, which give it a pink color. It is commonly used as a food seasoning and in various health and beauty products. It is also used in curing meats and preventing the production of botulinum toxin in meat.
