You can roll and bake the scraps from the trimmed tart shell to make little cookies for garnishing the finished tart. Sprinkle them with sanding sugar and bake them at the same time you blind bake the crust; watch to make sure they don't over-bake. You can also pop them in the oven at 325 degrees F for 10 minutes while the baked tart cools. If the filling curdles during the pie-making process, don't worry. It will come out fine.
