A pie is a baked dish which is usually made of a pastry dough casing that covers or completely contains a filling of various sweet or savoury ingredients.
In the USA "pie" almost always refers to the sweet type and one has to specify "meat pie" or pasty if you wish to have the savoury kind. In UK and most commonwealth countries, "pie" refers to savoury types.
