Melton Mowbray Pork Pie
Unlike the standard British pork pie, the Melton Mowbray variant is made with uncured pork, so the meat should be grey rather than pink. Also, they are traditionally cooked free-standing, so the sides should bow outwards.
In 2008 the EU granted Melton Mowbray Pork Pies "protected geographical indication" (PGI) status. This means that pies calling themselves Melton Mowbray must be made in the local area to the traditional recipe.
