Milk, cream, or for my non-dairy friends: non-milk alternatives such as coconut, soy, rice, or almond milk*
Filmjölk yogurt starter
Follow the directions that come with your yogurt starter to activate your culture.
Pour your milk or cream (The instructions for FILMJÖLK recommends cream over milk for a thick, Greek-style yogurt. Otherwise, use milk.) into a jar and stir in 1 tbsp of yogurt starter for every cup of milk/cream.
Cover with a cloth and let sit at room temperature until your yogurt has the consistency of custard, approximately 12 to 48 hours. It may take longer if your room temperature is cooler than 20 C.Screw on a tight-fitting lid and refrigerate until ready to serve.
*Note: To activate your yogurt starter, you will need to use pure cow or goat's milk. After that, you can use any alternative milk. If it doesn't thicken enough to your liking, you can strain it.
