What is Læsø Salt?
Læsø is well-known for its local seething salt, which is extracted from the very saline groundwater on the island. The large sea around the island contains approx. 2% salt, the groundwater on Rønnerne, on the other hand, can contain up to 14% salt. This level of salt makes it possible to build up a production and evaporate the water. In addition to the salt, the groundwater from the rønnerne contains a number of other minerals. The minerals help to give the salt its unique taste.
The working method of salt seethering has been known since the Middle Ages. The local seethering on Læsø stopped in the 17th century due to a royal ban. The ban was due to the large consumption of wood when seethering, which had cleared Læsø of forest areas. Around the 20th century, replanting of forest areas was started, which has made it possible to start the salt production again in 1991.
