Preheat oven to 300 degrees F. Lightly grease bottom and sides of a 2-quart square baking dish; set aside. Peel and coarsely shred sweet potatoes (about 4 cups). In a large bowl combine eggs, half-and-half, sugar, corn syrup, cornmeal, butter, vanilla, nutmeg, and salt. Stir in sweet potatoes, and 1/2 cup each of the coconut and the pecans. Transfer sweet potato mixture to prepared baking dish. (If desired, cover and refrigerate up to 24 hours.)

Bake, uncovered, for 1 hour. Sprinkle with remaining coconut and pecans. Bake, uncovered, 30 minutes more or until a knife inserted near center comes out clean. Cool about 30 minutes on wire rack. Serve warm. Makes 9 servings.
