I followed the crust recipe from Vermont Cheddar Apple Pie on KingArthurFlour.com. I just used Gruyere instead of Cheddar and all butter rather than with shortening. My apartment smells very cheesy for two days after baking it.
The crust came out a little tough after it cooled down. Maybe the cheese hardened up. Or maybe I over process the dough. I like it regardless. It's like eating apple pie with cheese sticks. Two birds with one stone.
