Peruvian pale pink salt has been used for 6 centuries by villagers of Maras and is now used by local Peruvian chefs because of its flavor & it has some unique health benefits. It contains magnesium, iron, calcium & zinc to help with stress, anemia & osteoporosis. In the Sacred Valley, evaporation ponds that locals refer to the salt mines have been used since the Inca period, if you put your hand in the stream, some minutes later your hand will be dry with a thorough dusting of salt on it.
