Book Ciphers...Help Needed

[retro]

if you have a recipe sounds like you have numbers. maybe they lead to page, line, word or page line character.

each ingredient numbers might lead to a line or character in that heading.

If you're talking about Rumrunners, I doubt it's a book cipher. 

More generally, if the ingredient amounts aren't helpful in solving a book cipher you can try the number equivalents of the letters of the ingredients, in various combinations.

EXAMPLE: 0.5 oz pineapple juice

First-second letters (pi=16-9)
First-second-third letters (pin=16-9-14)
First-last letters (pe=16-5)
Etc...
