A pie is a baked dish typically consisting of a pastry dough casing that encloses a sweet or savory filling. Sweet pies often feature fruits, nuts, preserves, brown sugar, sweetened vegetables, or fillings made with eggs and dairy. Savory pies, on the other hand, may contain meat, eggs, cheese, or a combination of meat and vegetables.
