If making a pie, roll out each round to a size that is big enough for your pie pan. If making mini tarts, roll out smaller circles. Top crust can either cover pie(s) or you can make cutouts.
To make the filling:
Position rack in center of the oven and preheat to 375°F.
Combine pear wedges, maple syrup, sugar, tapioca flour, lemon juice, crystalized ginger, vanilla extract, and lemon zest in large bowl to coat.
Place filling ingredients into pastry shell(s).
Top with pastry top crust or pastry cut outs such as leaves. If using a solid top crust make sure to cut slits or cut a center hole in the crust to allow steam to escape.
Brush top crust or cut outs with milk and sprinkle with sugar.
Place pie(or tarts) on a baking sheet so that the bottom of the pie crust will brown. Cover all of the edges of the pie crust so that they don’t over brown.
Place pie (or tarts) on the center rack of the oven. Bake until crust is golden brown and juices bubble, about 1 hour.
Transfer to rack and cool.
Makes one 9 inch pie that serves 6-8 or one dozen mini tarts.
