Cover the jar with a piece of cheesecloth or a clean breathable kitchen towel secured with a rubber band. This allows the mixture to breathe while keeping out dust.
Place the jar in a warm spot, roughly 20°C
Place the jar in a warm spot, roughly 20°C (68°F) to 22°C (72°F), away from direct sunlight. Let it sit undisturbed for 12 to 24 hours.
1 dayCheck the consistency
Check the consistency. Once it has thickened slightly and developed a tangy aroma, remove the cloth and stir or whisk the mixture until perfectly smooth.
Seal the jar with a tight lid and refrigerate
Seal the jar with a tight lid and refrigerate for at least 4 hours before serving. Cold temperature improves the texture and flavor.

A little kitchen wisdom
Ensure all equipment is thoroughly cleaned to prevent unwanted bacteria. The final consistency should be slightly thicker than regular milk but still pourable. In the Netherlands, it is often enjoyed cold with a sandwich for lunch.
