Hi Don. I don't recall the documentation team producing a document like the one you describe, but I will do some more investigation to see if there's anything I've missed.
In terms of producing a cookbook, for the next release of Visual COBOL/Enterprise Developer we will be adding some "Where do I start?" topics that direct you to relevant sections of the product documentation depending on your particular point of interest. It's not a cookbook, but it is hopefully a quick way of navigating to the information that you will find most useful.
I will let you know if we find a document like the one you describe.
