Answer 1

Sour cream, cheese, yogurt, etc. are ***NOT*** produced from ‘old rotten milk’ you take fresh milk, add different kinds of yeasts while strictly controlling temperatures and get the result we want. Making those products is very similar to making bread. If you used ‘old rotten milk’ to make those aforementioned products, you would be left with a very disgusting and unhealthy result.
