Can I use frozen pie crusts for this recipe?
Yes, frozen (9-inch) pie crusts work perfectly. Thaw according to package directions before filling and baking.
How thick should the raisin filling be?
The flour thickens the filling as it cooks on the stovetop and in the oven. It should be thick enough to coat a spoon but still spreadable when it cools slightly before adding to the crust.
Should I soak the raisins before using them?
No soaking needed. The raisins soften as they cook in the 2 cups of water during the filling preparation, absorbing moisture and plumping naturally.
How do I prevent a soggy bottom crust?
Bake on a lower oven rack to expose the bottom crust to direct heat. You can also pre-bake the bottom crust for 5 minutes before adding the filling.
Can I make the filling ahead of time?
Yes, prepare and cool the raisin filling up to 1 day in advance. Refrigerate in an airtight container, then bring to room temperature before filling the crust.
