I don't want to know much about chemistry (at least for the above topic )and even you won't care after reading what I have to say. I am from India and Ayurveda has the answer to many questions which in some cases modern medicine is still looking for.
So if it were harmful then some of our ancestors would have easily pointed it out. But i don't want this to be a debate, on a lighter note if somebody stops eating that skin,thinking its harmful then that person can be one of the biggest losers provided if he/she is born in Kolkata (Calcutta) India or may be if he/she is aware of Kolkata.
In case you are unaware then a short intro might help. Kolkata is located in West Bengal a state in India and the local people (Bengali people) speak a language called Bengali (Its the sweetest language of the world ).
As I said the sweetest language, it also reflects on their food habits. These people are crazy for sweets which are mostly made out of milk and the milk skin is the most important ingredient in this case. These people make some killer deserts which are world renowned. So let's come back to the point ,that is if you have tasted or still crave for Bengali deserts and the doctor comes to you and say that over boiling the milk can cause cancer , you will turn a deaf ear for sure.
So let's wrap it up.I myself being a Bengali can any day discard or don't give a shit about the scientific reason or the dangers if any if it comes in between us and our sweets.
Any way to the reader if you are unaware of Bengali sweet meats or deserts then at least once in you lifetime pay a visit to Kolkata (India) and btw we also cook killer food (fish meat anything you say).
Let me know if you want me to write a blog post about Bengali food and deserts. Thanks everbody and @timsaid.
Thanks for your answer! This was only a myth and milk/the skin on heated milk doesn't harm you. You can eat it without any problems.
I want to try some Bengali food now!
Yeah!! that was my main motive for the comment to introduce others to Bengali food. Cheers!!!
I had always liked the skin on the milk... when I was kid I used to compete with my cousin who would get more, but my grandma will always part it equally... absolutely nothing wrong with it whatsoever.
