This book was written in the same year as 'Dining with Sherlock Holmes'. The similarity between these two publications is striking.
But, which came first?
It is hard to say. Although, 'Dining with Sherlock Holmes' can be traced back to the 1973 Sherlokian repast in New York; so, may have better provenance.

Fanny Cradock's book has a number of charming pen and ink sketches at the start of each chapter, whereas Julia Carlson Rosenblatt's book is text only.
Both books contain almost exactly the same amount of pages.

At the end of the day judgment should be left to the success of the recipes - none of which I have yet attempted.
Although it should be noted that Fanny Cradock's Welsh Rarebit contains Worcestershire sauce, whereas Rosenblatt swaps this ingredient for cayenne pepper (possibly a substitute for the harder to source UK ingredient in the US?).

I would guess that Fanny Cradock's book may therefore have the edge on authenticity. But if so, it is by a whisker.

I would say that both books have merit. And, I do not believe that it would be too ostentatious to own both, as I do. ( )
