In the hot spring town of Laugarvatn, Iceland, the most pristine rye bread is baked in volcanic, muddy ground. Siggi Rafn Hilmarsson from Laugarvatn Fontana takes us through the making process step by step and welcomes us into his bakery, aka the hot springs of the lake in Laugarvatn. The sand by the lake can host from 10 to 15 tins of bread.
