Lingonberries (Vaccinium vitis-idaea) are to Scandinavians what blackberries are to Americans – an abundant wild fruit free for the taking by anyone with a basket, a harvesting fork, and the patience to pick through and clean their harvest. Produced by low, evergreen shrubs throughout Scandinavia’s forests, the tart red berries are much smaller and juicier than their distant cousin, the cranberry. Bursting with natural preservatives and pectin, lingonberries were invaluable to earlier generations of Scandinavians, for they could be kept for months at room temperature simply by placing them in jars of water (vattlingon) or by stirring the raw berries with a small amount of sugar to make rårörda lingon, an easy lingonberry jam (no cooking required).

Lingonberry jam (lingonsylt) always been very popular with traditional Swedish dishes. Fine lingonberry jam is prepared only with berries, sugar and, optionally, a small amount of water. Cheaper varieties are diluted with apples and/or pectin. The finest lingonberry “jam” is prepared fresh by just mixing berries and sugar, without boiling; this is called rårörda lingon or rørte tyttebær (raw-stirred lingonberries). Before the use of refined sugar became common in Sweden, lingonberry jam was prepared with lingonberries as the only ingredient. Because of the benzoic acid, which is found in high amounts in lingonberries, the berries keep well without any sugar or other preservatives. (Wikipedia)
