This is a lovely buttermilk pie recipe. The crust has a bit of cinnamon for extra flavor. The filling is rich with creamy buttermilk, with added flavor from lemon and vanilla.
For the crust, mix the flour, salt, cinnamon and sugar in a medium size bowl. Cut in the shortening using a pastry blender or 2 knives, until all the flour is blended in and the mixture consists of pea-size bits. Sprinkle the mixture with water, 1 tablespoon at a time. Toss lightly with a fork until the dough forms a ball.
Work the dough, pressing between your hands to form a 5-6 inch pancake. If the dough seems too sticky, wrap in plastic and refrigerate for 20-30 minutes. Dust the dough lightly with 1-2 extra tablespoons of flour.
Roll the dough in a circle between 2 sheets of waxed paper on a slightly dampened countertop. Peel off the top sheet of waxed paper, then trim the dough so that it has 1 inch lapping over the edges of a 9 inch pie plate. Turn the dough over onto the pie plate, pull the waxed paper away. And press the pastry to fit the pan. Fold the edge of the pastry under and flute the edges or press with fork tines.
For the pie, preheat the oven to 350°F.
In a bowl, combine the sugar and cornmeal. Add the eggs and buttermilk, mixing well. Add the butter, vanilla, lemon rind and lemon juice. Mix until blended. Pour into the pie shell and bake for 45 minutes. Or just until beginning to brown on top.
