Cheshire is an English cow's milk cheese produced in Cheshire, Flintshire, Staffordshire, Shropshire, and Denbighshire. This cheese has been produced for so long that it is even mentioned in the 11th-century Domesday Book. The texture of Cheshire cheese is crumbly and dense because the cattle were grazed on salt marshes, so the salt caused the cheese to ripen slowly, developing a crumbly texture in the process.
