Notes

**Please read through this whole recipe before making; there are several steps with making and baking the crust ahead, filling and baking with the blueberries and custard filling, and finally baking with the crumb topping. Plus cooling to let the custard set. Plan accordingly. You can even prepare the day before and enjoy its deliciousness the next day - if you can wait.
