Once cooled, it is separated by passing the liquid through a fine cloth, leaving the curd behind. Ricotta curds are creamy white in appearance, and slightly sweet in taste. The fat content changes depending on the brand and the type of milk used. However, ricotta also is made in aged varieties which are preservable for much longer. In the second millennium BC, ceramic vessels called milk boilers started to appear frequently and were apparently unique to the peninsula. These were designed to boil milk at high temperatures and prevent the milk from boiling over.

The fresh acid-coagulated cheeses produced with these boilers were probably made with whole milk. However, the production of rennet-coagulated cheese overtook the production of fresh whole-milk cheeses during the first millennium BC. Unlike the fresh acid-coagulated cheese, aged rennet-coagulated cheese could be preserved for much longer. The increased production of rennet-coagulated cheese led to a large supply of sweet whey as a byproduct. Cheesemakers then started using a new recipe, which used a mixture of whey and milk to make the traditional ricotta as it is known today. They described the production of rennet-coagulated cheese but did not write about milk boilers or acid-coagulated cheese. A likely reason is that ricotta was not profitable because its very short shelf life did not allow distribution to urban markets.

Ricotta was most likely consumed by the shepherds who made it. Even so, evidence from paintings and literature indicates that ricotta was known and likely eaten by Roman aristocrats, as well. Today, metal milk boilers are used, but production methods have changed little since ancient times. This means ricotta production is a low-yield process, considering the amount of whey required to produce it. The whey is heated to a near-boiling temperature, much hotter than during the production of the original cheese, of which the whey is a remnant.

The original ricotta is made of whey with the addition of a small amount of milk, but more recently ricotta has been made of whole milk, as well. It is milky-white and firm and used for grating or shaving. Salt is added as well. It is smeared on bread, mixed with tomato sauces for pasta, or added to vegetable dishes. Himalayan areas, notably in Bhutan, Sikkim, Darjeeling and parts of Nepal. However, paneer is mostly casein protein, similar to cottage cheese, while ricotta is made of all whey protein. While Italian ricotta is typically made from the whey of sheep, cow, goat, or Italian water buffalo milk, the American product is almost always made of cow’s milk whey.

While both types are low in fat and sodium, the Italian version is naturally sweet, while the American is a little saltier and more moist. It can be salted or sweetened for cooking purposes.

European culture, it having gone unwashed and containing all of the necessary bacteria to facilitate the ecology of cheese. The job of the cheesemaker is to control the spoiling of milk into cheese. This is not to say, of course, there is no room for variety or innovation, but a particular cheese needs to be made a particular way. The end product is very predictable.
