Sourdough breadmaking has had a real renaissance in recent years, with specialist artisan bakeries rolling out across Europe and the US, and more and more people cultivating their own batches at home. In Sweden the craze has been particularly intense and Stockholm is now home to the, let's face it, somewhat gimmicky "sourdough hotel". Located in the Urban Deli in the painfully hip Sofo district, the "hotel" charges 300 Swedish Crowns (£27) a week (a week!) to keep sourdoughs thriving while their owners go on holiday.
According to Jesper Konstantinov, part-owner of the Urban Deli, sourdough baking is popular among what he calls the socially conscious. And, he adds, "it's huge among stay-at-home-dads. They have really been a driving force in the Swedish sourdough craze. They are the same dads who come to us for tips on how to make their own sausages because they don't want to give their kids the commercially produced stuff. They don't trust it."
