" The problem with cooking meat this way [open fire] is that even if it does not burn, the valuable and tasty juices drip away and the meat dries and shrinks. Other cooks at other times got around this problem by wrapping the meat up to protect it - in leaves, for example. Or clay. Clay that, to another cook in perhaps, another time and place, felt just like dough. This last inspired step created the primitive meat pie - something medieval cooks called a 'bake-mete'. "
