Preheat oven to 190ºC . Heat 2 T. maple syrup and 1 tsp. butter in a heavy 25 cm ovenproof skillet over medium-high heat. Add apples and saute for about 5 minutes, or until slightly softened. Remove from heat. Using two spoons, arrange the slices, fanning them out from the center of the skillet. In a medium-sized mixing bowl, stir together cornmeal, flour, baking powder, salt and baking soda. In a small mixing bowl, beat together buttermilk, egg, remaining 1//4 cup maple syrup, remaining 1 T. melted butter and oil. Make a well in the center of the dry ingredients and pour in the buttermilk mixture. Stir with a wooden spoon until just combined. Spread the batter evenly over the apples and bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean. Invert onto a platter, cut into wedges and serve immediately, topped with more syrup.
