Use a mature, well-flavoured Cheddar, or a mixture of Cheddar and Parmesan, for these flaky cheese biscuits. Watch them carefully as they cook, since they turn very quickly from golden- to burned-brown!
Rub the butter into the flour in a bowl until it resembles fine breadcrumbs. Add the grated cheese and seasonings. Add the cold water to form a soft dough. Chill for 30 minutes. Roll out on a lightly floured surface to 6mm/¼
