Homemade pie crust weight: If you do not have a pie crust weight, here's how to make one using sugar. After you have placed your dough into your pie plate, press a sheet of foil paper onto the pie dough. Fill the center completely with granulate sugar and spread it out. The sugar acts as a weight so that the pie crust will not bubble up as it bakes. The sugar will NOT be affected in the oven and can be used afterwards.
