Boiling milk to check its freshnessEnter Your Question Title Here
I use skimmed milk and I have half a container dated 18th September (today is the 21st) and I seem to remember my mother telling me that if it would boil it would not be "off". It does not really smell off as I would know it by smell without having to check it and I have just had some in a cup of tea which did not taste peculiar. I am going to make custard with it before it has definitely turned sour. It is right now that I am not sure and remember my mother's advice.
