MAKES 1 (9-3/8-INCH) TART CRUST Be sure to use sweet rice flour, not regular white rice flour, for this crust. If you can’t find it, try a sweet rice flour–based all-purpose flour, such as Bob’s Red Mill 1 to 1. The crust, which pairs beautifully with fillings featuring pumpkin puree, chocolate, apples, or pears, can be shaped, tightly wrapped, and frozen for up to 1 week.
