1 1/2 cups cornmeal
1/2 cup all-purpose flour

1 teaspoon salt
1/2 teaspoon baking soda
2 eggs
1 cup buttermilk

In a bowl, combine the first six ingredients. In another bowl, whisk the eggs, buttermilk and oil. Add to the dry ingredients and stir just until moistened. Stir in jalapenos. Pour into a greased 9-in. square baking pan. Bake at 400 degrees F for 20-22 minutes or until a toothpick inserted near the center comes out clean. Cut into squares or wedges. Serve warm.
