Reducing the oven temperature from 425 degrees F to 375 degrees F after the initial 15 minutes prevents the pastry from burning before the fruit cooks through. All-purpose flour functions as the primary thickener here, binding the juices released by four cups of fresh blackberries during baking. Precise measurement of this starch is critical; too much flour creates a pasty consistency, while too little leaves the filling too runny to hold a slice. Pastry flour or arrowroot can replace all-purpose flour, though starches like arrowroot require lower heat thresholds and yield a glossier appearance in the finished gel. Bakers working with frozen berries must thaw and drain them thoroughly first, as excess moisture will overwhelm the flour ratio and prevent proper setting. Brushing the upper crust with milk before applying the remaining white sugar creates a granular, golden exterior crust texture. Cool the finished pie completely on a wire rack to allow the internal starches to finish retrograding and stabilize the slice structure.
