Unfortunately you CANNOT copyright the recipe, they are pretty much public domain. You CAN copyright/patent the process of making it though. Coke's secret formula is a secret because they can't copyright it, so once the secret gets out everyone can make Coke.
You cannot trademark ingredients, because they are not "unique". You may remember that Bill Gates and Microsoft tried to copyright windows and a judge said that it was too common a word, i.e. lacking uniqueness.
