*Blind Baking:
When blind baking (prebaking the pastry shell) for the Lemon Velvet Cream Pie, Alan uses a disposable 8-3/4 inch foil pie pan to help the pastry keep its shape. Snip the rim of the foil pie tin every 2 inches or so and fold the rim upwards. After fitting the dough in the pie plate and crimping the edge, place the foil pie tin on top of the dough. Fill the tin with dried beans or pie weights and bake as specified in the recipe.
