How do I add an existing cocktail to my Cocktail Book?
- Visit the cocktail's detail page.
- Below the cocktail, under the heading "Author tools", click Add.
The cocktail will be added to your Cocktail Book. If you wish to edit the Cocktail Book entry (to enter a rating, perhaps), click Edit. (The Edit list will be where the Add link was.)
Since you didn't enter this cocktail (i.e. it isn't your cocktail), you can't edit the cocktail recipe itself.
