Preheat oven to 400 degrees and place rack in middle position.
Line a baking sheet with parchment paper or spray with cooking spray.
In a medium bowl, thoroughly whisk together flour, sugar, baking powder and salt.
Stir in the fruit until evenly distributed.
Make a well in the center of the dry ingredients and pour in the cream.
Stir until everything is moistened and a soft dough is formed.
Scrape the dough onto a lightly floured counter and knead a few times, shaping it into a fat log about 8 inches long.
Cut in two, then gently shape each half into a smooth disk about 1 inch thick.
With a sharp knife, cut each disk into 4 pieces.
Arrange the 8 scones on the baking sheet, leaving as much room as possible between them.
Brush with milk, then sprinkle with sugar.
Bake for 7 minutes, then reduce heat to 350 degrees and bake 15 minutes longer.
Let cool on wire rack, then serve.
