I actually have that book, authored by Patrick O'Brian fans rabid enough to ransack 18th century cookbooks, apply some guesswork, and come up with recipes for all the stuff that Capt. Aubrey and Dr. Maturin eat.

(It's a work of mighty enthusiasm and misplaced scholarship, equivalent to the Klingonese Macbeth, or the scribblings of the Baker Street Irregulars.)

But, obviously, I haven't read it all the way through, or I'd have recalled the camel thing.
