Gamalost

Gamalost is a traditional Norwegian cheese. Gamalost, which translates as old cheese, was once a staple of the Norwegian diet. The name might be due to the texture of the surface, or the fact that it is an old tradition, not the ripening which may take as little as two weeks. Like many traditional Norwegian foods, such as flat bread, dry salted meats and stockfish, Gamalost could be stored for long periods without refrigeration. The brownish-yellow cheese is firm, moist, coarse and often granular. Gamalost is rich in protein with low fat content, measuring 1% fat and 50% protein. To make Gamalost, lactic starter is added to skimmed cow's milk, causing it to sour. After several days of souring, the milk is slowly heated, before the curds are separated and pressed into forms. After removal from the forms, mold is introduced onto the surface of the cheese, either by exposure to the wooden walls of the form that is only used for Gamalost, or rubbed on by hand in the traditional method. The cheese is then allowed to cure for four to five weeks. The ripening happens from outside inwards, so the center might be lighter than the parts near the exterior.
