Cornmeal works magic in waffles: It sweetens and lends whatever it's blended with a warm, golden glow. It also delivers the kind of crisp and crunch that won't wilt under fire. This batter, sweetened with maple syrup and tenderized with buttermilk, is wonderful made with coarse-grained, stone-ground cornmeal. Serious lovers of crisp should try making these in a waffle iron with shallow grids. Top the waffles with fresh orange segments, a simple mixture of sweetened oranges moistened with their own juice. Prepare them before you start the waffles and set aside or refrigerate until ready to serve.
