This mix - made with freshly ground flour, cornmeal, oats, buttermilk powder, baking soda and a touch of sugar - yields a Southern-style cornbread with a great crumb and rich corn flavor. Making the batter is as easy as adding an egg, hot water and oil or melted butter. The batter takes well to both sweet and savory additions. Fold in raisins, dates and walnuts for a sweet breakfast muffin. Or spice things up and add fresh corn kernels and chopped jalapeno. For a southern snack, crumble plain cornbread into a bowl and top it with a hearty pour of milk.
