Step 1
In ½ cup of cool water, dissolve the citric acid. Transfer the milk to a thick-bottomed vessel, and add the dissolved citric acid to it. Heat the milk stirring continuously, and when it starts boiling, add the liquid rennet mixed with ¼ cup of water. Lower the flame and let the milk simmer for a couple of minutes, stirring in between, before removing it from the heat. Do not disturb the milk for 15 minutes or till the yogurt is formed.
