Curd and fermented milk
Filmjölk
Swedish soured milk, mild and spoonable, eaten from a bowl with cereal or muesli at breakfast.
Filmjölk is a Swedish cultured milk made with mesophilic bacteria, those that work at room temperature rather than the warmth needed for yoghurt. It is mild, slightly sour and thicker than milk but thinner than yoghurt. Swedes eat it from a bowl at breakfast with cereal, muesli or lingonberry jam, and use it in baking.

Made step by step
Each drawing shows the operation for that step. Quantities and timings differ from house to house and herd to herd; this is one traditional way, in outline.
Step 1: Ferment Pour milk into a clean jar and stir in a spoonful of filmjölk. Step 2: Set Leave it covered at room temperature for about a day. Step 3: Set Chill once it has thickened. Step 4: Serve Serve in a bowl with cereal, muesli or jam. Finished Filmjölk, by share.
Room-temperature souring
Before cooling, milk in Scandinavian farmhouses soured on its own in the cool of a larder. Filmjölk comes from that tradition: a mild culture is added to milk, which is left at room temperature for about a day. A spoon of the last batch could start the next. Stretchy långfil, from northern Sweden, is a related soured milk with a ropy texture.
Mountain cows
The Fjäll, a small white polled cow of the Swedish mountains, was the cow of the summer farms, the fäbodar, where women took the herd for the season and made butter, cheese and soured milks. Several old Swedish breeds, including the Fjäll and the Swedish Red Polled, are now kept by enthusiasts.
