I bought these purely for my children, but I admit I love looking at these silly guys first thing in the morning. These are a bargain on Amazon right now (a set of 4 for $5.39).
Cecilia Hae-Jin Lee: Eating Korean
I would place this cookbook in my top 10 of all time. The recipes are delicious and each section is packed with the best of Korean home cooking. The stories are wonderful, too. Highly recommend.
Angelo M. Pellegrini: The Unprejudiced Palate
My favorite food-writer by far. A big thanks to childbearinghipster for turning me on to his writing. So inspiring. Start a garden and eat from it!
Irma S. Rombauer: The Joy of Cooking
(not the "All New", the old school one) I don't so much like this for main dish and salad recipes as for baked goods, sauces, and jams. I have my mother's copy, and when I was about 12, my favorite thing to do was to make tea sandwiches from this cookbook. Every weekend I'd make a couple of different kinds until I worked my way through all the spreads and fillings. A good basic cookbook.
Jacques Pepin: Jacques Pepin's Complete Techniques
This man has been teaching me to cook (on TV) since I was 9 years old. My Saturday mornings forever have been spent watching him on Public Television. I love him like he was one of my family.
Peter Berley: The Modern Vegetarian Kitchen
My most favorite veggie cookbook, and definitely in my Top 20 cookbooks list.
Anthony Bourdain: Les Halles Cookbook
O how I love this man.
Michael Ruhlman: The Making of a Chef
Not a cookbook, but still a must-read for anyone interested in cooking, chefs, and restaurants like I am.
Jamie Oliver: Jamie's Kitchen
The best of the Naked Chef bunch, IMO.
