Heavy cream, also known as heavy whipping cream or crème fraîche in some contexts, is the high-fat layer that rises to the top of whole milk when left undisturbed. This dairy product typically contains between 36-40% milk fat by weight, distinguishing it from lighter cream products such as light cream (18-30% fat) or half-and-half (10-18% fat). Heavy cream is an emulsion of fat globules suspended in water, with milk proteins and lactose as secondary components. The rich, smooth texture and slightly sweet dairy flavor make it a fundamental ingredient across Western and international cuisines.

Heavy cream can be sourced from grass-fed or grain-fed dairy cattle, and regional variations exist in fat content and processing methods. Pasteurized heavy cream is the most common form in retail settings, though ultra-pasteurized versions have extended shelf life. The ingredient's versatility stems from its ability to be whipped into peaks, heated without breaking, and used as both a finishing element and structural component in cooking and baking.

Heavy cream serves multiple functions in culinary applications, from enriching sauces and soups to creating whipped toppings and dessert bases. In European cuisine, it is essential for making beurre blanc, hollandaise variations, and classic French sauces. Heavy cream is whipped to stiff or soft peaks for use as a dessert topping, incorporated into mousses, panna cottas, and ice cream bases, and used as a binding agent in custards and cream fillings. In coffee preparation, heavy cream or half-and-half provides richness without the acidity of milk. It can be reduced over heat to concentrate flavor and create silky textures in both savory dishes (cream reductions with pan drippings) and sweet applications (caramel sauce, chocolate ganache). Heavy cream also stabilizes emulsions and adds fat-soluble flavor compounds to dishes.
