Sour Cream
What it is
Sour cream is a dairy product made by fermenting regular cream with certain kinds of lactic acid bacteria. This fermentation process causes the lactose to be converted into lactic acid, which gives the cream a tart flavor and a thicker consistency. It is a common ingredient in many cuisines, valued for its rich texture and tangy taste. It is typically sold in refrigerated sections of grocery stores.
How people cook with it
Sour cream is a versatile ingredient that can be used in both sweet and savory dishes. It adds richness and a subtle tang.
- Topping for baked potatoes
- Ingredient in dips and sauces

Sour cream can be stirred into soups and stews just before serving to add creaminess and a slight tang. It is excellent as a base for dips, mixed with herbs, spices, or other flavorings. In baking, it can contribute moisture and tenderness to cakes, muffins, and quick breads. It can also be used as a topping for chili, tacos, and other savory dishes, providing a cool contrast to spicy flavors. For a simple dessert topping, it pairs well with fruit or pie.
How it differs from similar foods
Compared to regular cream, sour cream has a much thicker texture and a distinct sour, tangy flavor due to the fermentation process. It is also less likely to curdle when heated than unfermented cream, making it more stable in cooked dishes.
Who it is for
Home cooks and professional chefs use sour cream to enhance the flavor and texture of a wide variety of dishes.
How to keep the rest
After opening, store any unused sour cream in its original container in the refrigerator. Ensure the lid is tightly sealed to prevent it from absorbing odors from other foods. It should be consumed within the recommended timeframe indicated on the packaging for best quality.
