The quintessential unprocessed Swedish condiment: fresh wild lingonberries gently stirred with granulated sugar until the crystals dissolve into a glossy, natural sweet-tart syrup.
Ensure berries are clean and dry. Place in a medium glass or ceramic bowl.
Pour granulated sugar over the berries. Stir gently with a spoon to coat every berry.
Stir occasionally over the course of 30-45 minutes. The sugar will draw out natural juices from the berries and dissolve completely without cooking.
Transfer glossy stirred berries to a jar. The natural benzoic acid preserves the berries in the fridge for weeks. Serve cold.
