Combine 1 1/2 cups sugar, 1/2 cup melted butter, 1 tablespoon plus 1 teaspoon cornmeal, 1 tablespoon white vinegar, 1 teaspoon vanilla, and 3 well-beaten eggs. Mix thoroughly. Pour into pie shell. Bake at 350 degrees for about 45 to 50 minutes, or until a knife inserted in the center comes out clean. (I use aluminum foil to protect the outer edge of the pie crust from getting too brown, since the cooking time is so long.) Remove the pie from the oven, and let it cool. You may cut it into slices while it is slightly warm. That's when it tastes the best! Otherwise, cool it completely, cover it, and let it sit on the counter until ready to use. If you are keeping it longer than 12 hours or so, store it in your refrigerator or freezer. This pie is beautiful and luscious! I hope you like it!
