I make yogurt at home regularly. I am not sure if I will be saving any money by making yogurt at home instead of buying in stores. But I like the taste of the homemade better than the store bought.
It’s really quite easy to make. First, bring the milk to a boil, reduce the heat and simmer it for few minutes till a layer of cream forms on top of the milk. Turn off the heat and let the milk cool down to lukewarm level. Now add one tablespoon of live active culture of yogurt to this milk, stir it once and cover the vessel with a lid. Keep the container in an oven or in a microwave (they act like incubators) undisturbed for about 8 to 12 hours. After this period, milk in liquid state will become semisolid - like yogurt. This is how you will know that the process of making yogurt is complete.
How much milk you need depends on how much yogurt you want to make. Small or large quantity, all it takes is adding one tablespoon of live active culture of yogurt. It’s that simple.
