Preheat oven to 425 degrees Fahrenheit.

In a large bowl, measure and combine flour, sugar, baking powder, baking soda, and salt.

Cut in cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs.

Add shredded apple and milk to the bowl.

Stir until a soft dough forms.

Turn the dough out onto a lightly floured surface.

Gently knead the dough 8 to 10 times.

Pat the dough into two 6-inch circles.

Place the circles on a greased baking sheet.

Brush the tops of the scones with milk.

Sprinkle the tops with sugar and cinnamon.

Score each circle into six pie-shaped wedges.

Bake for 15 minutes, or until golden brown and risen.

Serve warm with butter and marmalade.
