as a person who never knew how to make a cup of cocoa, I already die just from accidentally throwing the cocoa away. This is fine, and also, how do you actually make a cup of cocoa?
But I can't teach you how to make a cup of cocoa, it's something you will figure out yourself which is just a fancy way of saying "It's a matter of taste really, I personally just boil water, add milk, add cocoa, and call it a day" lol.
