Query: Why do I need starch in a pie?
Context: Starch is needed in a pie to help the fruit juices thicken! The heat of your oven causes the starch to bond with the water and sugar to create a network of starch that transforms the blueberries mixture into a thickened, cohesive filling. If you don’t use starch in a pie, the filling will be watery and unable to be sliced properly!
