Crumbly, or New Lancashire is a mass-produced, very young Lancashire made from a single day’s curd, with a firm texture and acidic flavour. Creamy Lancashire is aged for four to 12 weeks; Tasty Lancashire is 12 to 24 weeks old, and thus stronger in flavour. One producer, Singletons Dairy, has obtained a Protected Designation of Origin mark for its Beacon Fell Traditional Lancashire.
