What is
Feta cheese, a type of Greek cheese, is made from milk that is brined or pickled. The process of brining gives a tangy, salty and a crumbly consistency to feta cheese.
Soured milk is a food product, distinguished from spoiled milk, and is a general term for milk that has acquired a tart taste, either through the addition of an acid, such as lemon juice or vinegar, or through bacterial fermentation.
