Lingonberries contain a lot of naturally occurring benzoic acid, something that industry adds to many preserves and jams to help them keep. The levels are so high that lingonberries just don’t go bad.
You can use fresh or frozen berries. It makes no difference to the end result. Especially in northern Scandinavia and Finland, we eat sugared lingonberries on so many things, sweet and savoury and they all seem to benefit from a good scoop of sweet and astringent ruby loveliness.
