Anyone for some Worm Castles?!

It's getting just about lunch time, so my mind is turning to munchies! And what better tidbit to munch on but the ever-famous Hard Track, or sea biscuit, or as it is sometimes known as Worm Castle. Basically, made of flour and water and perhaps a little salt (unless sea water used). Actually the recipe goes back to ancient Roman times, carried with on their conquering journeys to far-away lands, these biscuits last a very long time.

Salt helps bind the gluten, and the shape, generally a 2" round, sometimes a small square, allowed for efficient travel. They would turn extremely hard, as they dried out, so they could be dipped in coffee, or water, or grog to soften. But invariably, as any food decays, worms or maggots made their way into these "delicacies", creating a very happy home or Castle, for themselves, eating their way in to stay, hence the term Worm Castle. Bon Appetit!
