A term for baking a pastry shell (pie crust) before it is filled. There are two methods used. 1. The unbaked shell is first pricked all over with a fork to prevent it from blistering and rising and then baked. 2. The unbaked shell is lined with foil or parchment paper, then filled with dried beans or rice, clean pebbles (a French practice) or specialty pie weights made of metal or ceramic. The weights and foil or parchment paper should be removed a few minutes before the baking time is over to allow the crust to brown evenly.
