Of all products made from milk, cheeses, in all their varied forms, are probably the source of the most outstanding textures. Cheeses can be hard and firm, moist, soft, creamy, crumbly, grainy, crunchy, sticky, or chewy. Their texture depends on a whole range of factors, especially the type of milk from which they are made, their fat content, and how they are produced. In addition, as a cheese undergoes change as it ripens, one that has been aged will be quite different from its newly made counterpart.
