I'm interested in doing some analysis of recipes for fun. Ideally, I would like to obtain open recipe database(s) behind {foodily, allrecipes, recipes, bigoven, cooking, cooks}.com or something like that.
I am interested in databases which have many variations of recipes, such as hundreds of slightly different chocolate chip cookie recipes (in statistical talk, I'm interested in doing a principal components analysis on chocolate cookie recipes).
APIs would be okay if there aren't any databases available for download. I saw this related recipe API: https://webapps.stackexchange.com/questions/19453/does-allrecipes-com-site-have-an-api (I'm not interested in pay APIs like yummly or food2fork)
Finally, (please correct me if I'm wrong), recipes aren't copyrightable in the basic format of: ingredients plus preparation directions (Publications International v Meredith Corp). I'm interested in these types of recipes.
