I have an encyclopedia of cooking as well, and I absolutely love it!! Unfortunately it's not the Better Homes and Garden's version. My aunt got me mine at Willams-Sonoma, and it's only one book! But, I love how I can look anything up when I need to know a technique or type of food.
I am also a sucker for easy and delicious meals, so my favorite book would have to be The Best of 30-Minute Recipes from Around the World. All the recipes are super-easy and don't require much work, but are also delicious. My favorite recipe is a Hearty Minestrone that I have featured on my blog!
Another fav. is The Sopranos cookbook... but I still have yet to tackle the more difficult recipes!
