Pie
The crust is a proof.
A pie is a circle you are allowed to cut.
Everything about it is measured before it is baked: the flour, the fat, the heat, the time. The oven is the only argument that convinces a room.
A pie that waits for the knife is a theorem with a crust. π never ends. Pie ends when it is shared.
A 10-inch tin holds 1.23 times what a 9-inch tin holds. Multiply the filling by 1.23.
