Place rack above centre of oven. Preheat oven to 450F (230C). Grease a baking sheet.
Using a fork, stir flour with baking powder, salt and pepper in a large bowl. Work in cold butter until mixture is crumbly. Stir in cheese.
Make a well in centre. Pour in milk and stir just until moistened. Turn out onto a floured cutting board. Divide in half and pat each portion into a 6 inch (15 cm) circle about 3/4 inch (2 cm) thick.
Cut each into 6 wedges. Lift wedges onto greased baking sheet, placing about 1 inch (2.5 cm) apart for crusty-sided scones or 1/2 inch (1 cm) apart for soft-sided scones. Bake above oven centre until golden, from 10 to 12 minutes.
