Dana, if it's something you want to do, do it. These days there are a lot of different options.
When I decided to write my first book (over ten years ago, so a lot has changed since then) I started the work on it and when I had about 40 recipes tested and written out, I got a copy of Writer's Market and using it as a guide, put together a submission and then found about 100 publishers through the book that accepted unsolicited submissions and sent them out. There were many rejections, but there were also a few offers to publish and I ended up with both a Canadian publisher and an American publisher buying the US rights. The first run of 10,000 copies sold out and a few years ago a second edition was put out by my publisher.
The second book I did had a much narrower focus and wasn't a good fit with my publisher, so I decided to self-publish it. The book-writing was very similar in both books, but self-publishing the second came with a lot more work when it was time to sell the books (I printed over 6000 copies and still have stacks). I was lucky that sellers knew who I was from the first book, so took a chance on the second. As a first time writer, it would be more difficult to get your book into stores.
But these days, there are great options. One I'm looking into for my next book is a program Amazon runs. Basically your book goes up on their site as an e-book, but they also print on demand. So if somebody wants to order a hard copy of the book, they order it from Amazon and then it gets printed. There are other companies that are POD, but for my purposes, I think the Amazon program makes the most sense. (https://www.createspace.com/)
Lots of options, even if you are an unknown. But if it's something you really want to do, start working on it.
