Blåbärssoppa
Swedes have drunk blåbärssoppa for generations, warm on a winter morning and cold from a cup after the Vasaloppet ski race, where skiers are handed it at every station. It is a thin, deep purple soup of bilberries or blueberries, sweetened and thickened just enough with potato starch to coat the tongue. The common mistake is boiling the soup after adding the starch: it turns stringy and then thins out again, so take it off the heat as soon as it thickens. Chef's tip: wild bilberries give a far deeper colour and flavour than cultivated blueberries, and frozen ones work perfectly.
