Camembert (ˈkæməmbɛər, also UK-mɒmbɛər, kamɑ̃bɛʁ) is a moist, soft, creamy, surface-ripened cow's milk cheese. It was first made in the late 18th century in Camembert, Normandy, in northwest France. It is sometimes compared in look and taste to brie cheese, albeit with a slightly lower butterfat content than brie's typical 60% and 75% by weight. The first camembert was made from unpasteurized milk, and the AOC variety "Camembert de Normandie" (approximately 10% of the production) is required by law to be made only with unpasteurized milk. Many modern cheesemakers outside of Normandy, France, however, use pasteurized milk for reasons of safety, compliance with regulations, or convenience. The cheese is made by inoculating warmed cow milk with mesophilic bacteria, then adding rennet and allowing the mixture to coagulate. The curd is then cut into roughly 1 cm (1/2 inch) cubes, salted, and transferred to low cylindrical camembert molds. The molds are turned every six to twelve hours to allow the whey to drain evenly from the cut curds; after 48 hours, each mold contains a flat, cylindrical, solid cheese mass weighing generally 250 grams (about 9 oz). At this point the fresh cheese is hard, crumbly, and bland. The surface of each cheese is then sprayed with an aqueous suspension of the mold Penicillium camemberti, and the cheeses are left to ripen for a legally required minimum of three weeks. This affinage produces the distinctive bloomy, edible rind and creamy interior texture characteristic of the cheese. Once the cheeses are sufficiently ripe, they are wrapped in paper and may be placed in wooden boxes for transport. Camembert was reputedly first made in 1791 by Marie Harel, a farmer from Normandy, following advice from a priest who came from Brie. She is credited with having refined a previously existing cheese recipe from the Pays d'Auge region and having launched it into the wider world. She passed her secrets on to her daughter, whose husband, Victor Paynel, presented one of his wife's best cheeses to Napoleon III, who gave to it his royal seal of approval.
