Blåbärssoppa (warm bilberry drink)
Every first Sunday of March, the 90-kilometre Vasaloppet ski race from Sälen to Mora is fuelled by blåbärssoppa: volunteers at the feeding stations hand thousands of skiers paper cups of the warm purple drink, and Swedes drink it from thermoses on winter hikes, after skating and on the ski slopes. It is made from wild bilberries, the small dark forest berries with purple flesh, cooked with sugar and thickened with potato starch so it is just thick enough to coat the cup. It is sweet, softly tart and tastes intensely of berries, with a silky, almost glossy body. The common mistake is stirring the starch straight into the hot pot: it forms jelly lumps at once. Always mix potato starch with cold water first, take the pot off the boil, then stir it in and bring back just to a bubble; long boiling thins it again. It is ready when it turns glossy and coats a spoon in a thin film. Bilberries are sold frozen in Nordic shops; cultivated blueberries work too, with a squeeze of lemon for sharpness. Chef's tip: it is just as good cold the next day, or served as a soup with whipped cream and almond biscuits.
