Preheat the oven to 220°C/200°C Fan. Line a baking tray or baking sheet with baking paper or parchment paper.
Grate the cheeses, keeping aside 40 grams of the cheddar to place on top of the scones before baking.
50 grams parmesan, 100 grams cheddar
In a large bowl whisk together the flour, baking powder, salt, mustard, cayenne pepper, and paprika. Grate the butter or cut it into small blocks. Rub the butter into the dry ingredients until it resembles fine breadcrumbs with some small pieces of butter scattered throughout the flour (or work the butter into the flour using a pastry cutter). Add the grated cheese into the flour, and mix through with your fingers until well distributed.
310 grams plain flour, 3 teaspoons baking powder, 60 grams butter, 50 grams parmesan, ½ teaspoon mustard powder, ½ teaspoon cayenne pepper, 1 teaspoon paprika, ¼ - ½ teaspoon of table salt, 100 grams cheddar
Pour the milk into the flour mixture, using a fork, stir to make a rough dough.
200 mL milk
Place the cheese scone dough onto a lightly floured surface. Press the dough into a rectangle. Then using a sharp knife or a bench scraper, cut the dough into thirds and fold the outer edges onto the middle section. Press down using your hands or a rolling pin until the dough is about an inch or 3 cm thick. Repeat this twice.
Either using a cookie cutter or knife cut 6 to 8 large scones. If using a round cookie cutter, bring together the left-over dough, by kneading the dough together and forming a disk or square to cut out additional scones. Try to work with the dough as little as possible.
Place the cut scones on the lined baking sheet. Using a pastry brush, brush the tops of the scones with the milk and sprinkle the leftover cheddar over the tops of the scones.
3 tablespoons milk
Bake for approximately 15 minutes. The scones would have risen, and be golden brown in colour. Remove from the oven and place on a wire cooling rack to cool down slightly before serving warm with butter.
