A pie is a baked dish which is usually made of a pastry dough casing that contains a filling of various sweet or savoury ingredients. Sweet pies may be filled with fruit, nuts, fruit preserves, brown sugar, sweetened vegetables, or with thicker fillings based on eggs and dairy. Savoury pies may be filled with meat, eggs and cheese or a mixture of meat and vegetables.
