Yogurt Preparation

 There are 4 basic steps:
1. “Scald” the milk, which means heat it up to a specific heat and hold it there for long enough to kill the unwanted bacteria.
2. Let the milk cool down to just above body temperature.
3. Add the bacteria, either in the form of a yogurt starter package or in a small amount of yogurt from a previous batch.
4. Keep at a warm temperature for long enough for the bacteria to do its job. This can take anywhere from 4 to 18 hours depending on the amount, the temperature and the strain of bacteria used.
