Ever since a special "hotel" for yeast culture opened in Stockholm, it's more or less been official: Swedish foodies love sourdough. The Parisian born baker, Sébastien Boudet, has been living here for 11 years and is known as one of Sweden's biggest proponents of sourdough. For Boudet, baking is about philosophy. He founded the Petite France bakery in Stockholm, which won best café from Dagens Nyheter newspaper for three years in a row. I caught up with him this summer when Swedish Radio had a big do for their summer speakers. He was one of those picked to lead his own show for a day on the airwaves.
