Heat oven to 375°. Grease an 8- or 9-inch skillet; place over medium heat while preparing cornbread batter. Combine cornmeal, salt, and baking soda; blend well. Stir in melted shortening; add sour cream, corn, and eggs, blending well. Spoon half of the batter into the greased hot skillet. Sprinkle batter with the cheese and chile peppers; cover with remaining batter. Bake Mexican Cornbread at 375° for 35 to 40 minutes, until nicely browned
