Step 1

Preheat oven to 190 C/ 170 C fan.

Step 2

Using your fingertips, rub the butter into the flour until it resembles coarse bread crumbs.

Step 3

Add the baking powder, bicarbonate of soda, salt, pepper and 100 grams of the grated mature cheddar and stir well.

Step 4

Add the milk, mustard and the Worcestershire sauce and stir with a wooden spoon until it forms a soft dough.

Step 5

Knead briefly and roll out to a 1.5 - 2 cm thickness on a floured board. Cut into rounds using a circular cutter and place onto the baking tray.

Step 6

Sprinkle with the remaining grated cheddar cheese and bake in the centre of the oven for 12-15 minutes, until the cheese on top is golden and bubbly.

Step 7

Transfer to a wire rack to cool completely and store in an airtight container.
