Key Lime Custard Tart

Fully baking or partially baking a crust (also known as blind baking) before adding the filling can prevent a soggy crust. Use heavy-duty aluminum foil to line it, or fold regular aluminum foil to create a double thickness. For the weights, use small ceramic or metal weights, dried beans or rice. The crust may be cooled, covered and stored at room temperature or up to overnight.
