There is one recipe from Captain Marryat that is never going to make my Cooking with the Captain series, and that's Marryat's instructions for "geo-graffy", which Admiral Smyth defined in his Sailor's Word-Book as "a beverage made by seamen of burnt biscuit boiled in water." In Marryat's description, it sounds more like a means of making bad water more palatable:
Take a tin-pot, go to the scuttle-butt (having obtained permission from the quarter-deck), and draw off about half a pint of very offensive smelling water. To this add a gill of vinegar and a ship's biscuit broke up into small pieces. Stir it well up with the fore-finger; and then with the fore-finger and thumb you may pull out the pieces of biscuit, and eat them as fast as you please, drinking the liquor to wash all down.
Now this would be the very composition to hand round to the Geographical Society. It is not christened geography without a reason; the vinegar and water representing the green sea, and the pieces of biscuit floating in it, the continents and islands which are washed by it.
