What each ingredient does

Blueberries
Provide the main fruit flavor and the juice that becomes the filling.
Sugar
Adds sweetness and balances the tartness of the berries.
Cornstarch
Thickens the released berry juices into a sliceable filling when heated.
Vinegar
Adds acidity that brightens the blueberry flavor.
Pie crust
Holds the filling in shape and browns during baking.

The step that matters

Adding the cornstarch mixture. Cornstarch thickens only when the hot berry liquid reaches a simmer and holds it there briefly. If the cornstarch is added to a mixture that is not hot enough, or is not cooked long enough, the filling stays thin and runs out when the pie is cut.
