Cooking site Digital Chef announced an agreement with cookbook publishers Random House, Crown/Clarkson Potter, HarperCollins, and others that allows consumers to try recipes before buying cookbooks by browsing a weekly selection or searching by type of food, region, or author. Other interactive features then allow users to adjust recipes for any number of servings, get nutrition information, and prepare a shopping list. The site will offer a link to Amazon.com so users can easily purchase the cookbooks.
