This pie combines fresh plums and blueberries with sugar, cornstarch, lemon juice, vanilla, cinnamon, and nutmeg in a homemade butter crust. The filling strikes a perfect balance between sweet blueberries and tart plums, while the flaky crust is made using cold butter.
Learn how to cook Plum Blueberry Pie by making a buttery crust with cold butter and flour, then filling it with fresh plums and blueberries tossed with sugar, cornstarch and spices. Create a lattice top, bake at 190°C for 20 minutes, reduce to 175°C for 35-40 minutes until golden and bubbling, then cool completely before slicing.
Runny fillings typically result from insufficient thickener or cooling time. Use 3 tablespoons of cornstarch for juicy fruits like plums and blueberries, and allow the pie to cool completely (at least 3 hours) before slicing. Pre-cooking some of the fruit can also help release and thicken juices.
The secrets to flaky crust are using very cold butter, handling the dough minimally, and chilling it before rolling. The cold butter pieces create steam pockets during baking, forming flaky layers. Don't overwork the dough, and ensure it rests in the refrigerator for at least an hour.
Yes, frozen fruits work well in pie fillings, but don't thaw them first as this releases excess moisture. Add an extra tablespoon of cornstarch to account for additional liquid, and extend the baking time by about 10-15 minutes. The lattice top helps release the extra steam from frozen fruits.
