To roast a pie, it must be made with a thick crust, and the filling must be quite moist. The pie should be placed in a hot oven, and as soon as it begins to brown, the heat should be reduced. If the crust is not thick enough to prevent the filling from soaking through, it will be ruined. A pie that is to be roasted should be baked in a pan, and the pan should be large enough to hold the pie and any juices that may escape.
