Travel Pies!

I found an interesting little monograph on how pies were used in medieval times to preserve meats for extensive periods of times, especially for traveling. the pies in Pyes de Pares aren't all that much like modern pies: the crust is designed to protect the food inside, and so is thick and rough, and salty to the point of being inedible.

The interesting thing is this method of preservation seems to work quite well for periods of several weeks, and the paper actually has tests by a microbiology lab to demonstrate this.  So this might be something to think about the next time people want to save on food costs at a convention.
