Soak cherries in warm water. Let stand until softened, 1 hour. Drain and discard liquid. Preheat oven to 375 F. In a medium bowl, mix together all-purpose flour, wheat flour, sugar, baking powder, baking soda, salt, and nutmeg. Using a pastry blender cut butter into flour mixture until coarse crumbs form. Mix together egg yolk and buttermilk. Make a well in the center of flour mixture. Add egg mixture and cherries all at once to well, tossing with a fork until a soft dough forms. On a floured surface, knead dough 10 times. Using a floured rolling pin, roll dough to a 1 in. thickness. Using a floured 3 in. heart-shaped cookie cutter, cut out scones. Gather trimmings, roll dough to a 1 in. thickness, and cut out more scones. Place scones, 1 in. apart, on an ungreased baking sheet. Bake until golden, 18 to 20 min. Transfer to a wire rack to cool. Dust with confectioners' sugar.
