Hello, One way to publish that wasn't available a few year ago is to publish the book on line through a service provided by Amazon where the book is sold digitally for their Kindle product. Here is the link https://dtp.amazon.com/mn/signin/188-6642795-0199227
The other option is to print the book your self and higher a printer just to print the cover, you can even publish the cover if you print it in paperback, You would use a comb type binding popular with many cookbooks. The new publishing programs with your computer will let you self publish a quality product. The $400 wanted by the printed is hard to evaluate without knowing the quantity.
