The coarse La Baleine Sea salt is used when you like the crunch in your dishes; as the salt crystals are large.
The French La Baleine Company has excelled in using nature and salt marches and salt tables doing most of the work in creating their Mediterranean sea salt. Salt marches are a large collection of shallow lands through which the sea water is collected and moved up to the salt tables where the water is evaporated by wind and sun leaving the flavorful salt behind. This process takes place from March until September under the watchful eyes of the 'saliniers', the salt farmers. They maintain the marches and salt tables, so every year the process can be repeated and salt can be collected.
La Baleine also makes a fine sea salt that is perfect for every day use.
