Baking rye bread in the boiling ground has a long tradition in the village of Laugarvatn. As you probably know, Iceland can be very cold, and this place is no exception. At Laugarvatn, we have exceptional heat underground. We bake our special rye bread in the sand close to one of the main hot springs. Under the sand are small cracks where the boiling water is able to get through, with a temperature of around 100 degrees Celsius. Our guests are often curious about how to make it at home, so we wanted to share the baking method and process for home baking. If you have a hot spring somewhere nearby, we encourage you to try our method, but be very careful about the boiling water.
