Cream or creme is a dairy product that is composed of the higher-butterfat layer skimmed from the top of raw milk before homogenization.
In the raw milk, over time, the lighter fat rises to the top. In the
industrial production of cream this process is accelerated by using centrifuges
called "separators". In many countries, cream is sold in several grades
depending on total butterfat content. Cream can be dried to a powder
for shipment to distant markets.
Cream produced by cows (particularly Jersey cattle) grazing on natural pasture often contains some natural carotenoid pigments derived from the plants they eat; this gives the cream a slight yellow tone, hence the name of the yellowish-white colour cream. Cream from cows fed indoors, on grain or grain-based pellets, is white.
In the United States, cream is usually sold as:
- Half and half (10.5–18% fat)
- Light, coffee, or table cream (18–30% fat)
- Medium cream (25% fat)
- Whipping or light whipping cream (30–36% fat)
- Heavy whipping cream (36% or more)
- Extra-heavy or manufacturer's cream (38–40% or more), generally not available at retail.
In the United Kingdom, cream is usually sold as:
- Half cream (12%)
- Single cream or light cream (18%)
- Whipping cream (35%)
- Double cream (48%)
Other cream products
Sour cream in the U.S. is cream (18% or more milk fat) that has been subjected to a bacterial culture that produces lactic acid (0.5%+), which sours and thickens it.
Creme fraiche is a heavy cream slightly soured with bacterial culture, but not as sour or as thick as American sour cream. Mexican crema (or cream espesa) is similar to creme fraiche. Smetana is a Central and Eastern European sour cream.
In the UK, clotted cream (similar to Indian malai) is a very high-fat (55%) product processed with heat.
Butter is made by churning cream.
Whipped cream
Cream with 30% or more of fat can be turned into whipped cream
by mixing it with air. This roughly doubles the cream's volume as air
bubbles are captured in a network of fat droplets. (Whipped cream is
said to have been invented in 1671 by Francois Vatel for a banquet in honour of Louis XIV,
though it is likely that it was actually known long before this.) If
the whipping is continued, the fat droplets stick together and form butter; the remaining liquid is buttermilk.
Whipped cream is sold ready-to-use in pressurized containers, and is colloquially called squirty cream. Nitrous oxide is used as a propellant, and when the cream leaves the nozzle, it produces four times
the volume of whipped cream, i.e., twice the volume produced by
whipping air into it. Using this technique, it may also be prepared in
reusable dispensers, similar to a seltzer siphon bottle, using inexpensive disposable nitrous oxide cartridges.
Chantilly cream (French: creme Chantilly)
Chantilly cream is whipped cream with sugar and vanilla.
Creme as an ingredient
Cream is used as an ingredient in many foods, including ice cream, many sauces, soups, and some custard bases, and also uses for cakes.
In the United States of America, cream (usually light cream or half-and-half) is often added to coffee.
