I think a key to a good pie is the crust, so getting the temp right for the crust is important.
I did a rustic apple tart on the pizza stone of my BGE and it was fantastic. There was just a hint of smoke but the crust was amazing.
I cooked a pumpkin pie in a stone pie dish in my gas grill one year we did not have power. No smoke flavor but the crust and the pie was perfect.
I'll share a secret ingredient for the crust of an apple pie: use applejack brandy instead of water. Put it in the freezer and it will be ice cold but not frozen. And, the alcohol cooks off faster than water leaving a flakey crust.
I have a bottle of Laird's smooth blend 80 proof I use.
And a shot for the cook and its all good.
