Why can't i heat up milk in the kettle?!


Question: Why can't i heat up milk in the kettle?
I just poured milk into the kettle, thinking it would heat up and boil like water, and I could drink warm milk. Unfortunately, that's not what happened. It overflowed the kettle and went all over the counter. Why did this happen? Why couldn't it just boil and make that whistling sound that it's ready?

Afterwards, I went to pour the boiling milk in a glass cup. I held the glass cup while pouring the milk and it shattered. I don't understand, why did this happen?

Is it possible to heat up milk safely? If so, how?

Answers:

1) When milk warms up it forms a skin over it's surface
that holds the heat in .. causing it to 'erupt' when it
comes up to the boil. It is therefore much safer to heat
up milk in something where you can see it and switch
off the heat as soon as it starts to bubble and rise up.
2) Pouring a hot liquid into a cold glass will shatter the
glass because the heat of the liquid will try to make the
glass expand (glass can't and so it breaks).
Always put a metal spoon in a glass before you pour a
hot liquid in .. the metal will take the heat first and the
glass won't break.



You can heat milk in a kettle, but you can't heat milk to the boil or it will do exactly what you experienced: make a big mess all over the place.

Heat milk in a saucepan on low on the stovetop. Low and slow is the way to go. Heat it just until bubbles barely begin to form around the perimeter.



since you do not have an asbestos mouth you can't possibly drink it at boiling anyway so why heat it that hot??
And why it behaves differently than water?
Milk contains protein and will foam when it boils, just like beans do.



Try heating it up in the microwave
