Making cheese scones is a straightforward process, but attention to detail is key. Follow these steps to achieve the ultimate fluffy texture and rich flavor.

Step 1: Preheat the Oven

1. Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.

Step 2: Prepare the Dry Ingredients

2. In a large mixing bowl, combine the flour, baking powder, salt, black pepper, and mustard powder. Mix well to ensure even distribution.

Step 3: Incorporate the Butter

3. Add the chilled, cubed butter to the flour mixture. Use a pastry cutter or your fingers to rub the butter into the flour until the mixture resembles coarse breadcrumbs.

Step 4: Add Cheese and Chives

4. Stir in the grated cheddar cheese and chopped chives, ensuring they are evenly distributed throughout the mixture.

Step 5: Form the Dough

5. Gradually add the milk to the dry ingredients, mixing gently with a fork or spatula until the dough begins to come together. Be careful not to overwork the dough.

Step 6: Shape the Scones

6. Turn the dough out onto a floured surface and gently knead it a few times to bring it together. Roll out the dough to about 1-inch thickness.
7. Use a round cutter to shape the scones and place them on the prepared baking sheet.

Step 7: Optional Egg Wash

8. For a golden finish, beat the egg and brush it lightly over the tops of the scones.

Step 8: Bake

9. Bake the scones in the preheated oven for 15-20 minutes, or until they are golden brown and cooked through.

Step 9: Cool and Serve

10. Allow the scones to cool on a wire rack for a few minutes before serving.
