Campos Santos Flor de Sal from Castro Marim is a type of artisanal sea salt that is harvested from the salt marshes of the Guadiana River estuary in Portugal. It is known for its delicate salt crystals and high mineral content, which is derived from pure Atlantic Ocean water. The salt is produced using traditional methods and is not processed or treated with any additives. It is commonly used as a seasoning for fish, meat, barbecue dishes, and salads. Additionally, it comes with a hand-made and hand-painted terracotta vessel, to hold the salt.
