One of my absolute favorite food blogs is Heidi Swanson's 101 Cookbooks. Heidi is a talented writer, designer, photographer, cook and cookbook author in addition to being a very sweet person. Her blog is an exploration of recipes from her vast cookbook collection.
She is one of the first bloggers to publish a cookbook, Cook 1.0.
If you are in San Francisco today, though it's rotten weather, Heidi will be at the Ferry Plaza Farmer's Market from 10:30-11:30 doing a cooking demonstration and signing books.
