The Vegetarian Flavor Bible is an awesome book. End of review, go buy it.
Actually I'm only half kidding, because for what it is, it is just that awesome. It is not a traditional recipe book, but more, the best book you could have if you want to create your own recipes. It is essentially a list of ingredients that go well with other ingredients. So, you could decide, I am making a pear pie today, what spice would take the pie to a next level? The Vegetarian Flavor Bible will tell you.
Easily the most referenced book I have, and it worked as a great tool, when I was working in a restaurant, trying to figure out what to do with an ingredient that had to be used at tomorrows lunch serving.
