Lingonberry jam (Swedish: lingonsylt, Norwegian: tyttebærsyltetøy, Danish: tyttebærsyltetøj, Estonian: pohlamoos, Finnish: puolukkahillo, German: Preiselbeermarmelade, Latvian: brūkleņu ievārījums, Lithuanian: bruknių uogienė) is a staple food in Northern European cuisine and otherwise highly popular in Central and Eastern Europe. Lingonberries (Vaccinium vitis-idaea) grow on a short evergreen shrub in the Arctic tundra throughout the Northern Hemisphere from Eurasia to North America.  
In Sweden lingonberries are often sold as jam and juice, and as a key ingredient in dishes. Addition of preservatives or thickeners is not necessary since lingonberries naturally contain benzoic acid which has a preservative effect and pectin which makes the jam gel. Lingonberry jam is often served with meat courses such as meatballs, beef stew or liver dishes; regionally, they are even served with fried herring. Traditional dishes such as kroppkakor, pitepalt, potato cake, kåldolmar, mustamakkara and black pudding are also commonly combined with lingonberries. The jam can be paired even with mashed potatoes and the traditional oatmeal porridge, sometimes together with cinnamon. 
Fine lingonberry jam is prepared with berries, sugar and, optionally, a small amount of water. Cheaper varieties can be diluted with apples. Sweeten lingonberries (rårörda lingon) or (rørte tyttebær) is prepared fresh by just mixing berries and sugar, without boiling. Because of the benzoic acid, which is found in high amounts in lingonberries, the berries keep well without any preservatives.
