Sour milk
Milk acidified through natural or controlled fermentation, consumed as a drink or used in cooking.

About Sour milk
Sour milk is milk whose acidity has increased through fermentation or deliberate acidification. It may be made from different types of milk and by natural or controlled processes, resulting in variation in thickness, aroma and degree of tang.
It is consumed as a drink or used in cooking and baking. Some forms remain pourable, while others thicken or separate; the name does not indicate whether the milk was cultured with selected microorganisms or soured by another method. It is distinct from a specific cultured dairy product unless the product is identified.
