Somewhere, in some kitchen, someone with unused custard they didn't want to waste, decided that sugar, apples and cinnamon buried in a crust - called a coffin in merry old England - made too plain a dessert for a forward looking nation. So, they took the custard and poured it over the apples only to discover they had created another problem. The crust used to cover the apples made no sense with a custard filling. Fortunately, American ingenuity surfaced and deduced that a crumbly streusel with a gazillion calories would be a perfect topper for the pie. That's my take on how apple custard pie with streusel topping came to be. I hope you'll take it with a grain of salt.
