Enclosure makes a meal movable
A pasty is not merely filling wrapped in crust. The dough creates a carrier, boundary, portion, and pocket of retained heat. Its robust bake and crimp must resist knocks, damp, cooling, and the pressure of a filling that still contains enough moisture to remain edible. Cut and proportion matter because free liquid can migrate into the pastry and weaken it after steam stops escaping. The filling therefore has to cooperate with the shell rather than behave like a bowl stew trapped by accident. Enclosure makes a complete meal movable, allowing structure to replace the absent plate without making the food illegible when opened or divided.
