I did try Ginsberg's Danish rye bread recipe, mainly because there was a BBGA forum thread on it that piqued my interest, but I had several problems with it that I attribute to things I did incorrectly. (I also ran short on a couple of ingredients.) I'll try it again before I write a formal review of it here.
I do want to get back into testing Ginsberg recipes more frequently. Hopefully this will re-start the project.
