Cheddar Cheese produced since at least the 12th century in the village of Cheddar in Somerset, England. It is a relatively hard cheese. It is today the most popular cheese in the UK, and among the most appreciated cheeses in United States, Australia and Canada. Since 2003, the West Country farmhouse Cheddar has the Protected Designation of Origin appellation. Unless artificially coloured, as it often is, Cheddar cheese color ranges from off-white to pale yellow.
Fun fact: during the Second World War period, as part of war rationing, most milk in Britain was used to make one single kind of cheese, “government cheddar”: this almost resulted in wiping out all other cheese production.
