Do you have the book already written? If not, you need to get several categories completed. Once that is done, you must locate publishers that publish recipe books. It is easiest for me to look at a updated Writer's Market book, sometimes available at the library, but very often checked out. I found their website: http://www.writersmarket.com/ Looks like you can join their newsletter for free.
You must follow the publisher's guidelines specifically or they won't even look at your work. Research the guidelines of several publishers and do not be discouraged if they send you a rejection letter, just mark them off your list and keep going. Make sure you understand the copyright laws and the possibility of you losing those rights once a publisher buys the book from you, which is not normally the practice.
Dont expect to get rich. Writers are arts and must struggle most of the time.
If you are interested in self publishing, for family and friends let me know and I'll give you the info on that, talk you through it, or I can do it for you. As a self publisher, you will have to probably settle on less than perfect binding, (no hardback), but you can get the ring binders, or use stabling as an option.
