Lingonberry jam[a] is a staple of 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.

[1][2] In Sweden, lingonberries may be sold as jam and juice, and as a key ingredient in dishes and desserts.

[3] Fine lingonberry jam is prepared with berries, sugar and, optionally, a small amount of water.

Sweetened lingonberries (rårörda lingon) or (rørte tyttebær) is prepared fresh by just mixing berries and sugar, without boiling.
