I'm currently reading Harold McGee's
On Food & Cooking. I normally have two books going at once, or a book and a magazine, particularly if one is cumbersome and difficult to lug around for lunchtime reading.
Others recently read:
I'm Just Here for the Food, Alton Brown (now signed

)
The Art of Cooking, MFK Fisher (loved all of it)
It Must Have Been Something I Ate, Jeffrey Steingarten
Cookwise, Shirley Corriher, though I had to return it to the library before I finished
Up next:
How to Bake, Nick Malgieri (my textbook for pastry school)
Cookwise, gonna buy it AND finish it!
I'm Just Here for More Food, Alton Brown's baking book
I've also recently been perusing
Baking Illustrated,
Baking with Julia, and, of course,
Mastering the Art of French Cooking.I spied
The Tummy Trilogies at Borders last week (picking up
How to Cook Everything for a non-foodie, non-cook friend). Since I loved
Tepper Isn't Going Out, I should have just picked it up. Instead, it will probably go into the same Amazon order with my other stuff after labor day.
Non-cooking books - Is there such a thing? Actually, I just started
Eats, Shoots & Leaves, by Lynne Truss, subtitled as "The Zero Tolerance Approach to Punctuation," as my lunchtime tome.
Yes, I'm a geek.
Sorry, don't know how to make the Amazon link to enrich the coffers of eGullet.
