A surprising find
In the process of doing some searches relating to bread this past week, I encountered several recipes from a site named www.igaalliance.com. In refining my search somewhat, I learned that the site would not display any information if I tried to visit the site by directly entering the address (or subaddresses). However, if I used the search term "bread" and told Google to limit the search to the domain www.igaalliance.com, it would return a number of pdf links. Each pdf is a separate recipe, presumably for use by IGA member stores. None of the documents I viewed had any statements about copyright or proprietary information.
Whether there are recipes for things other than breads, I don't know. I haven't looked into that.
