2. Deep Apple Pie with Butterscotch and Oaty Crumble**

This pie is the antithesis of those simple plate apple pies well-loved in Scottish homes. This one is deep and bulging with apples and topped with a crunchy oaty topping. It is hearty and extravagant, a contrast to the humbler yet still delicious plate apple pie of yore!

If you want to make this the day before, I recommend removing the outer ring of the tin when the pie is completely cold, then reheating it on its base in a medium oven until warm.
