Preheat oven to 400°. In a large bowl, combine flour, sugar, baking powder and baking soda. Cut in butter until the mixture resembles coarse crumbs. Combine yogurt and 1/4 cup milk; stir into crumb mixture just until moistened. Knead in cherries and chips.
On a greased baking sheet, pat dough into a 9-in. circle. Cut into 8 wedges; separate wedges. Brush with remaining milk. If desired, sprinkle with sugar. Bake until golden brown, 20-25 minutes. Serve warm. Freeze option: Freeze cooled scones in freezer containers. To use, thaw at room temperature. Or, microwave each scone on high until heated through, 20-30 seconds.
Cranberry Chip Scones: Substitute dried cranberries for the cherries. Use white or semisweet chips. Blueberry Chip Scones: Substitute dried blueberries for the cherries.
