Toss fruit with sugar, stir in yolks and turn into a buttered 8x8" pan.
Sprinkle with cinnamon. In a bowl, combine flour, baking powder, sugar
and salt and toss lightly to mix. With a pastry blender, cut butter into
dry ingredients until crumbly. Add milk, stirring until smooth, then
lightly fold in egg whites. Spoon over fruit. Bake at 350 for 25 to 30
minutes, or until brown and crusty.
