Smitten Kitchen - This is one of my favorite sites. I've had a lot of luck with recipes I've tried (even if a few of them seem a little labor intensive), and the pictures that accompany the recipes are food porn in the best sense. Besides the beautiful food photography and the great recipes, it features The. Cutest. Baby. EVER! I'm not the kind of person who falls over at the sight of a baby, but this kid is adorable.
Kitchen Window: NPR - I'm an NPR junkie, and the Kitchen Window feature is always a fascinating read. While the recipes are good, my favorite thing about this site is the food writing that accompanies the recipes. I'm a sucker for a good essay on food, and Kitchen Window always deliver.
Roadfood.com - This site makes me miss having a car. Jane and Michael Stern, as well as others, write about food finds that are sometimes off the beaten path but are always worth the trip and effort.
The Crepes of Wrath - The motto of this site is that "great food doesn't have to be expensive or time consuming, and the recipes definitely live up to the motto. The recipes are usually fairly simple, and there's a wonderful selection of recipes to choose from (just check out the index if you don't believe me). This Mandarin chicken recipe is one of my favorites.
