Put the flour and cold, cubed butter in a bowl and rub together until you have an even crumb.
Stir in the cheese and pepper.
Add 1 tbsp of cold water and cut through with a cutlery knife. Give a little bit of the mixture a squeeze. If it comes together, it’s ready. If it’s dry and sandy, cut in up to another 1 tbsp water.
Gather up the pieces and knead together only as much as it takes to get a smooth ball of dough.
Roll the dough into a cylinder with a length of 24cm (9.5 inches) and a diameter of 4cm (1.5 inches). Wrap in greaseproof paper or plastic wrap and place in the fridge to rest and chill for 15 minutes.
While the dough chills, preheat the oven to 170C (150C fan / 340F).
Slice the dough into 1cm (½ inch) cookies.
Place them on a lined baking tray and prick each one a few times with a fork.
Bake for 20-25 minutes until they've taken on just a golden colour.
Allow to cool for 5 minutes. Transfer to a wire rack to cool completely.
