Cheese, did you know?.. When milk turns sour or curdles, it separates into a thin, runny liquid and white, fatty lumps. The liquid is called whey and the lumps are called curds. The curds are used to make cheese. It takes approximately ten litres of milk to make one litre of cheese. Cheddar, one of England’s oldest cheeses, is made from cow’s milk. The cheese originates from the village of Cheddar in Somerset, southwest England. Cheddar has been produced since at least the 12th century. Cheddar was actually considered a luxury product until the 19th century when Joseph Harding, a Somerset dairyman, invented a cheese mill capable of mass production. Cheddar is ripened for up to two years. The French cheese, brie, on the other hand, takes only a month to ripen. Swiss cheese is full of holes. Bacteria in the cheese give off bubbles of gas, which make the holes. Thanks to cartoons, many children think the holes are made by mice! Cheese-makers often combine cheeses to make new ones.
