Sour cream comes from cream, a milk by-product that rises to the top of pasteurized milk before it goes through homogenization. To make sour cream, the milk cream goes through fermentation by bacteria that produce lactic acid, giving it a distinctly sour taste. The lactic acid also thickens the cream. Many manufacturers add certain ingredients to enhance the taste and texture of sour cream, such as carrageenan or modified food starches. Most sour creams contain between 14-18% milk fat as well. Sour cream is a well-loved ingredient in European, American and Tex-Mex cuisines; recipes that use sour cream include baked potatoes, beef stroganoff, and tacos and nachos. It is also useful as a dip for snacks such as crackers and potato chips.

Cream cheese starts out as a blend of milk and cream. Lactic acid is added to the mixture to start the thickening and fermentation process, giving cream cheese a mild, tangy taste. Once the mixture reaches a certain texture and thickness, low heat (126–145 °F) is applied to stop the fermentation. Manufacturers add other ingredients, such as guar or carob gums, to maintain the texture of the cheese and to extend its shelf life. Because of its cream content, cream cheese has a higher proportion of milk fat compared to other cheeses at 33%. It is popular as a spread on bread and pastries, and is the main ingredient in cheesecake. Aside from these uses, it could be used as a substitute for butter in dishes such as mashed potatoes and cakes.
