'Cook-through' blogs, a blog where an entire cookbook is gone through page by page, recipe by recipe and, of course, written about, are becoming more popular as amateur chefs look for arduous tasks to complete. Several holy grails of the cooking world are at the heart of these 'cook-through' blogs including Thomas Keller's 'French Laundry Cookbook,' the British cookbook 'The Whole Beast' which has a cult-like following, 'Gourmet' magazine's 2004 edition of 'The Gourmet Cookbook' which boasts an impressive 1,300 recipes, and Dorie Greenspan's 'Baking,' whose author is one of the most popular baking writers in the United States. The writers of these blogs are not making money off their pursuits and in fact are spending thousands of dollars in ingredients (groceries for 'The Gourmet Cookbook' are estimated at $30,000). Most do their blogging in their free time while holding down professional jobs in such areas as public-relations, computer-graphics, mathematics, and neuroscience. Few have any great sense or desire that their projects will amount to anything more than their blogs, although Carole Blymire, whose blog 'French Laundry at Home' attracts 5,000 visitors a day, has filmed a Food Network pilot and has been approached about writing a cookbook. The first blog (Julie/Julia Project) that tackled an entire cookbook was done so in 2002 by Julie Powell who systematically went through Julia Child's 'Mastering the Art of French Cooking.'
