Fresh Blueberry Pie is an easy blueberry pie recipe using fresh blueberries over a creamy layer of sweet buttermilk custard filling. Simply fill a pie crust shell with a five minute cream filling, bake, and top with an easy homemade blueberry sauce."
One way to check if the custard filling is set is the top will look slightly puffed out and dry. Around the edges the custard may start to crack slightly.
