If you are interested in learning more about where your food comes from or eating more locally, there are two books that I know of that should be on your summer "must read" list.
The first is Animal, Vegetable, Mineral by Barbara Kingsolver. She chronicals the journey of her family as they take a challenge to eat food that they produce themselves or purchase from farmers within 100 miles from their house. It is informative, and filled with lots of good stories as you'd expect from Kingsolver. Some of the recipes and tips are on her website and one of these days I am really hoping to try my hand at making cheese http://www.animalvegetablemiracle.com/
The other is Omnivore's Dilemma: A Natural History of Four Meals by Michael Pollan. This books is also combination information and personal experience. The author dives into the origin of our food from the politics of corn to the hidden secrets of mass-produced organic food, to the question of whether or not to eat meat and finishes with foraging for mushrooms.
I'd love to see comments of any other suggestions of books that you've read on this month's food topic.
