I remember a product called Beef Fry, which was basically bacon for the kosher crowd. I ate it once, a lifetime ago, and I remember thinking it was quite awful, although I don't remember why. Probably has more to do the particular product and cooking method than with "beef bacon" in general, which I have no doubt can be great, because why not? I also look forward to following this.
When I entered "beef fry" into Google many (very many) hits came back with "Kerala style beef fry," which seems to be a big thing. So perhaps @Kerala can weigh in on that?
