Cream is a thick, rich part of milk that forms when milk sits still, rises to the top, and makes foods thicker and tastier.
Cream is the fattier layer that forms when milk sits still; tiny drops of fat gather and rise to the top because fat is lighter than the watery part of milk.
Cream comes from whole milk, and in big dairies machines called separators or centrifuges spin milk fast to pull the fat out more quickly.
Cream adds richness and a smooth texture to foods. It makes ice cream creamy, helps sauces and soups taste full, makes puddings and cakes softer, and can be whipped into a light topping for pies and fruit.
Countries set rules about what to call cream and how much fat it must have. For example, Australia and New Zealand say plain cream should have at least 35% fat; in the United States, creams range from about 12% to 36% or more, with whipping cream usually 33–36% and heavy cream at least 36%.
Some creams have tiny amounts of thickeners or stabilizers like alginate, carrageenan, or gelatin to keep cream smooth, stop water from separating, and help whipped cream hold its shape longer.
Butter is made by churning cream until the fat clumps together and the watery part (buttermilk) separates.
