How to make cherry coke?
Very easy! If you want the Signiture Coca-Cola flavour, just add 1/3 a can of cherry-juice concentrate to a liter of Coke. If not, use any off-brand Cola and do the same thing. You can also make your own cola: that is my preference!
You can't. Coke has a secret ingredient so you will never be able to make it at home.
