Preheat oven to 400°F.
8-inch square baking pan, lightly greased.
In food processor, combine cornmeal, flour, sugar, baking powder, baking soda and salt. Pulse to blend. Add butter and pulse until mixture resembles coarse crumbs. In a measuring cup, combine buttermilk, egg yolks and jalapeno pepper and beat well. Pour over cornmeal mixture and pulse just until blended.
In a mixer on high speed, beat egg whites with ¼ teaspoons baking soda, dissolved in 1 tablespoons water until stiff peaks form.
Fold in cheese. Fold in cornmeal mixture and spoon into prepared pan. Bake in preheated oven until top is golden and springs back, about 25 minutes. Let cool in pan on a wire rack for 5 minutes. Serve warm. Makes 8 servings.
VARIATION: Cheesy Chipotle Cornbread: Substitute 1 minced chipotle pepper in adobo sauce for the jalapeno.
TIP: Not only does pulsing blend the dry ingredients, it also aerates them slightly, contributing to a lighter result.
