Yogurt is a healthy food that can be made at home. One way to make it is to first buy some yogurt from a store or purchase dry yogurt culture. Add two small spoonfuls of the yogurt to two cups of milk. This will be the starter for your own yogurt. A cup in the United States is two hundred forty milliliters.

When making yogurt, it is very important to have clean equipment, clean hands and good temperature control.
Pour eight cups of milk into a large cooking pot. Heat the milk to eighty-five degrees Celsius. Then cool the milk quickly to forty-three degrees. To do this, you can put the cooking pot in cool water.
