" Preheat oven to 325 degrees. Butter a 9-inch round cake pan. Line bottom with parchment cut to fit, and butter parchment. Dust with flour, and tap out excess. Combine sour cream, vanilla, zest, and juice. In a separate bowl, whisk flour, baking powder, baking soda, and salt. Beat butter and sugar with a mixer on medium-high speed until pale and fluffy. Add eggs and whites, 1 at a time, beating well after each addition. Beat in sour cream mixture. Reduce speed to low, and beat in flour mixture until just combined. Transfer to pan, and smooth top. Bake until a toothpick comes out clean, 40 to 45 minutes. Let cool in pan on a wire rack for 5 minutes, then turn out cake onto rack to cool completely. (Cake can be stored in an airtight container at room temperature overnight.) Before serving, dust with confectioners&amp;#039; sugar, and arrange flowers on top."^^<http://www.w3.org/2001/XMLSchema#string>
