1/3 c dried cherries 
1/4 tsp cream of tartar
1/2 c boiling water 
1/4 c butter, room temp
1 1/2 c flour 
1 egg, separated
1 1/2 Tbs sugar 
1/4 c sour cream
1/2 Tbs baking powder 
1/4 tsp salt
1/3 c + 1 Tbsp half-and-half cream
3/4 tsp almond extract

Soak cherries in hot water for 10 minutes and then drain and set aside. Combine the dry ingredients in a mixing bowl. Using a pastry blender, cut in the butter until mixture resembles coarse crumbs. Set aside. In a small bowl, mix together the egg yolk, sour cream, cream and extract. Add this to the flour mixture and stir until a soft dough forms. Mix in the cherries and then knead the dough lightly on a floured surface (just until dough can be handled). Shape dough into a ball and pat into a 6-inch circle on a greased baking sheet. Cut into six wedges and brush with beaten egg white and then sprinkle with sugar.Bake at 400 degrees F. for 15 to 20 minutes. Makes 6 scones.
