I found a recipe by Brave Tart (Stella Parks) for pie crust that's blind baked at 350F. I'm using it for one pie but I have a Cook's Illustrated Dutch Apple Pie recipe that uses a different recipe for the crust and bakes it at 425F. The recipe calls for using white sugar to weight the crust when blind baking, which is really awesome because I don't have any pie weights and I've been really concerned about using dirty pennies.
I'm worried that the sugar will melt at this temperature. Will I need to find different pie weights or can I bake the pie crust for longer at the lower temperature and have it come out nicely?
