Cream cheese is a fresh, rich cow's-milk cheese set with acid. It was developed in the United States in the late nineteenth century, and it is made to spread.
It has no rind and it is not aged. American Neufchâtel is a lower-fat relative under US rules. French Neufchâtel is a different cheese, a bloomy round from Normandy.
History
The usual origin story places cream cheese with a dairyman named William Lawrence, in the town of Neufchâtel in New York, in the 1870s. He set a rich fresh cheese in the image of French Neufchâtel, and the American product took its own path. It became smoother, richer, and a thing to spread rather than a small ripened cheese.
The brand name Philadelphia, which many people treat as the cheese itself, was a marketing name. It pointed at the city's reputation for good food. It did not mean the cheese was invented in Philadelphia. Factories in New York state made the early product. In the twentieth century, cream cheese became part of American eating: the bagel with a thick layer of it, the New York cheesecake, and the frosted cake.
How it is made
Cream cheese starts with milk enriched with cream. Acid, rather than a long ripening, sets the curd. The curd is separated from the whey, smoothed, and salted. There is no cheddaring, no wash of the rind, and no months in a cellar. The goal is a tight, spreadable paste that stays in a foil block or a tub.
Small changes in moisture and fat change the feel. A firmer block holds a slice on a cold bagel. A whipped tub spreads with a knife straight from the refrigerator. American Neufchâtel, in the grocery sense, is the leaner relative of this same fresh cheese. It is not the French Neufchâtel of Normandy, which grows a white rind and is eaten as a ripened cheese. The shared name is a historical echo, not a shared product.
Taste
Plain cream cheese tastes of sweet milk, cream, and a light tang. It should not taste sour, cheesy in a cellar way, or bitter. The texture is the other half of the flavor. It should feel smooth, not grainy, and not watery.
Flavorings are common: chives, garlic, berries, smoked salmon mixed in at the table. Those are additions. The cheese underneath should still taste clean. A sharp acidic smell, or a watery puddle in the package, means it is past its life. Fresh cream cheese does not improve with age.
In the kitchen
Spread it cold, or let it soften before it is beaten. The classic uses are a bagel, a slice of dark bread with smoked salmon, a cheesecake, and a frosting. It also makes a quick herb spread, and it enriches a dip. Heat it gently. A hard boil will split it into grainy curds and fat.
Do not ask it to melt across a pizza or to grate over pasta. It is not mozzarella, and it is not Parmesan. In a baked cheesecake it sets again as it cools, which is why that cake works. In a savory sauce, add it off the boil and keep the heat low. Mascarpone is richer and sweeter. Quark is tangier and leaner. Neither is a straight swap in a New York cheesecake.
Around the world
Cream cheese is now made in many countries, because the bagel and the cheesecake traveled with it. The United States remains the reference. A New York bagel shop, a diner cheesecake, and a supermarket block are the three faces of the same cheese. Britain, Canada, and other places sell their own blocks for the same jobs.
The name is not a place name, and it is not protected. What matters is the style: a fresh, acid-set, spreadable cow's-milk cheese with no rind. A garlic-and-herb fresh cheese such as Boursin is a seasoned cousin, already flavored. Plain cream cheese is the blank one, which is why bakers depend on it.
