These Icelandic Bakers Use Hot Springs to Make Their Delicious Bread

It might sound crazy but Icelandic bakers are tapping into the geothermal power of the land to bake their bread.

The technique, dating back over 200 years, has been passed down between generations of bakers and is still practised today.

Iceland lies on the fault line between the North American and Eurasian tectonic plates and has a particularly active topography.

Sigurður Rafn Hilmarsson in action

Each week Sigurður Rafn Hilmarsson, the owner of Laugarvatn Fontana geothermal baths produces around 70 loaves by baking the mixture inside the ground, keeping some for his family and selling the rest.

Digging just 30 centimetres below the black volcanic sand reveals a bubbling pool of water -which can reach temperatures of 95 degrees celsius – into which the pot is placed and left for 24 hours.

The results are a thick, sweet bread that is often compared in appearance and texture to cake. According to locals it’s best served with simple, salty meats like pickled fish.

It’s estimated that about 70% of Iceland is heated by geothermal energy from springs, however this renewable source comes at a price.
New springs have been known to pop up in unexpected places following seismic activity, destroying roads and even homes.

2 years.


It's the personal contact, the personal experiences. I love meeting people from all over the world... I really like getting to know everyone and feeling like I'm traveling with a group of friends.


I have so many places on my list, but I would really lobe to go to Africa. I consider myself an “adventure girl” and Africa feels like the ULTIMATE adventure!
