Cornmeal Biscuits

Preheat oven to 425 degrees. In a food processor or large bowl, combine 1 1/2 C. of the cornmeal with the flour, salt, sugar, cayenne pepper, baking powder and baking soda. Cut the butter into dry ingredients until the mixture is about the texture of cornmeal. Separately mix the egg with the buttermilk, and stir all but 2 Tbs. of this liquid into the dry mixture. Mix just enough to make a uniformly moistened dough. Dust a clean board with half the remaining cornmeal, and place on dough. Sprinkle the top with the remaining cornmeal, and with floured hands, gently push the dough into a circle about a 1/2" thick. Cut with a 2 inch biscuit cutter, and place biscuits close together on a greased baking sheet. Brush top of the biscuits with reserved buttermilk mixture. Bake in the preheated oven until puffed and brown, about 12 minutes. Serve warm.
