Why milk foam is used in Cappuccino if it is being left in a cup after finish and people don't drink that foam?

People eat the foam.

Also its just what a cappucino is.

And there is probably a scientific answer as well, how foam increases surface area of the milk and thusly increases how much you taste the milk. Maybe the milk even works as isolation layer keeping the cappucino warm for longer...

I don't know, I don't like to drink foam on my coffee even if I want some milk in it 😬 weird invention for sure

@SomeRandomFrenchGirl Thanks for opinion... yup, instead of something different can be done for visual effects in coffee
