I have been following the “roast apple slices before putting into pie crust” approach from Bon Appétit when making apple pies. The Thanksgiving pie this year was about five pounds of sliced apples, mixed with about a cup of maple syrup, and roasted at 350 F for 25 minutes. They should be tender but not dehydrated (a big *no* on the convection oven). The roasted apples are mixed with 2-3 tablespoons of flour and drizzled with more maple syrup. They are then added to a walnut pie crust and baked for another 20-30 minutes.
