101 Cookbooks is a wonderful food blog. Each week Heidi Swanson, food photographer and cookbook collector posts a recipe and short essay about one of the things she has made that week. It's a very clean and attractive blog with lists of her favorite cookbooks, a nice portfolio of her food photographs and good links.
Another fun cooking site which I've come across in the bloggies nominations is ismyblogburning this site holds a monthly virtual group recipe event where a theme is chosen and recipes are submitted from all over the web.
