Adapted from the Barefoot Contessa Family Style Cookbook, 2002. At the intro of this recipe Ina Garten says that there were days that her specialty food shop would bake 2,000 of these muffins on a Saturday morning and by 9:30AM, they would all be gone! I changed the recipe just a bit, instead of using 2 1/2 cups all-purpose white flour, I split the flour between all-purpose white flour and wheat flour. You don't have to do this, if you don't want to. I always try to incorporate wheat flour into recipes that call for flour.
