Cream is a dairy product that is composed of the higher-butterfat layer skimmed from the top of milk before homogenization. In un-homogenized milk, the fat, which is less dense, will eventually rise 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 the total butterfat content. Cream can be dried to a powder for shipment to distant markets.
Cream skimmed from milk may be called "sweet cream" to distinguish it from whey cream skimmed from whey, a by-product of cheese-making. Whey cream has a lower fat content and tastes more salty, tangy and "cheesy".[1] They are also used in variety of food product.
Cream produced by cattle (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 color, cream. Cream from goat's milk, or from cows fed indoors on grain or grain-based pellets, is white.
Types
)
Different grades of cream are distinguished by their fat content, whether they have been heat-treated, whipped, and so on. In many jurisdictions, there are regulations for each type.
USA
In the United States, cream is usually sold as:
- Half and half (10.5–18% fat)
- Light cream (18–30% fat)
- Light Whipping cream (30–36% fat)
- Heavy cream (36% or more)
Not all grades are defined by all jurisdictions, and the exact fat content ranges vary. The above figures are based on the Code of Federal Regulations, Title 21, Part 131[2][3]
Australia
In Australia, the levels of fat in cream are not regulated, therefore labels are only under the control of the manufacturers. A general guideline is as follows:
Extra light (or 'lite'): 12–12.5% fat.
Light (or 'lite'): 18–20% fat.
Pure cream: 35–56% fat, without artificial thickeners.
Thickened cream: 35–36.5% fat, with added gelatine and/or other thickeners to give the cream a creamier texture, also possibly with stabilisers to aid the consistency of whipped cream (this would be the cream to use for whipped cream, not necessarily for cooking)
Single cream: Recipes calling for 'single cream' are referring to pure or thickened cream with about 35% fat.
Double cream: 48–60% fat.[4]
UK
In the United Kingdom, the types of cream are legally defined[5] as followed:
| Name | Minimum milk fat | Additional definition | Main uses |
|---|---|---|---|
| Clotted cream | 55% | is heat treated | Served as it is. A traditional part of a Cream tea. |
| Extra-Thick Double cream | 48% | is heat treated then quickly cooled | Thickest available fresh cream, spooned onto pies, puddings, and desserts (cannot be poured due to its consistency) |
| Double cream | 48% | Whips easily and thickest for puddings and desserts, can be piped once whipped | |
| Whipping cream | 35% | Whips well but lighter, can be piped once whipped | |
| Whipped cream | 35% | has been whipped | Decorations on cakes, topping for ice cream, fruit and so on. |
| Sterilised cream | 23% | is sterilised | |
| Cream or single cream | 18% | is not sterilised | Poured over puddings, used in sauces |
| Sterilised half cream | 12% | is sterilised | |
| Half cream | 12% | is not sterilised | Uncommon, some cocktails |
)
Canada
Canadian cream definitions are similar to those used in the United States, except for that of "light cream". In Canada, "light cream" is low-fat cream, with 5% or 6% fat. Another form of cream available in Canada is "cereal cream", which is approximately mid-way between 5% cream and coffee cream in fat content.
| Name | Minimum milk fat | Additional definition | Main uses |
|---|---|---|---|
| Whipping cream | 35% | Whips well but lighter, can be piped | |
| Whipped cream | 35% | has been whipped | Decorations on cakes, topping for ice cream, strawberries and so on. |
| Cream or single cream | 18% | Poured over puddings, used in sauces | |
| Half cream (half and half) | 12% (can be 10%) | Added to coffee |
Japan
In Japan, cream sold in supermarkets is usually between 35% and 48% butterfat.
Switzerland
In Switzerland, the types of cream are legally defined[6] as follows:
| English[7] | German | French | Italian | Typical milk fat wt% | Minimum milk fat wt% |
|---|---|---|---|---|---|
| Double cream | Doppelrahm | double-crème | doppia panna | 45% | 45% |
| Full cream Whipping cream Cream | Vollrahm Schlagrahm Rahm Sahne | crème entière crème à fouetter crème | panna intera panna da montare panna | 35% | 35% |
| Half cream | Halbrahm | demi-crème | mezza panna | 25% | 15% |
| Coffee cream | Kaffeerahm | crème à café | panna da caffè | 15% | 15% |
Sour cream and crème fraîche (German: Sauerrahm, Crème fraîche; French: crème acidulée, crème fraîche; Italian: panna acidula, crème fraîche) are defined as cream soured by bacterial cultures.
Thick cream (German: verdickter Rahm; French: crème épaissie; Italian: panna addensata) is defined as cream thickened using thickening agents.
Processing and additives
Cream may have thickening agents and stabilisers added. Thickeners include sodium alginate, carrageenan, gelatine, sodium bicarbonate, tetrasodium pyrophosphate, and alginic acid[8]:296.[9]
Other processing may be carried out. For example, cream has a tendency to produce oily globules (called "feathering") when added to coffee. The stability of the cream may be increased by increasing the non-fat solids content, which can be done by partial demineralisation and addition of sodium caseinate, although this is expensive.[8]:297
Other cream products
)
Butter is made by churning cream to separate the butterfat and buttermilk. This can be done by hand or by machine.
Whipped cream is made by whisking or mixing air into cream with more than 30% fat, to turn the liquid cream into a soft solid. Nitrous oxide may also be used to make whipped cream.
Sour cream, common in many countries including the U.S., Canada and Australia, is cream (12 to 16% or more milk fat) that has been subjected to a bacterial culture that produces lactic acid (0.5%+), which sours and thickens it.
Crème fraîche (28% milk fat) is slightly soured with bacterial culture, but not as sour or as thick as sour cream. Mexican crema (or cream espesa) is similar to crème fraîche.
Smetana is a heavy cream product (15-40% milk fat) Central and Eastern European sweet or sour cream.
Rjome or rømme is Norwegian sour cream containing 35% milk fat, similar to Icelandic sýrður rjómi.
Clotted cream, common in the United Kingdom, is made through a process that starts by slowly heating whole milk to produce a very high-fat (55%) product. This is similar to Indian malai.
Ingredient
Cream is used as an ingredient in many foods, including ice cream, many sauces, soups, stews, puddings, and some custard bases, and is also used for cakes. Irish cream is an alcoholic liqueur which blends cream with whiskey, and often honey, wine, or coffee. Cream is also used in curries such as masala dishes.
Cream (usually light/single cream or half and half) is often added to coffee in the USA.
For cooking purposes, both single and double cream can be used in cooking, although the former can separate when heated, usually if there is a high acid content. Most UK chefs always use double cream or full-fat crème fraîche when cream is added to a hot sauce, to prevent any problem with it separating or "splitting". In sweet and savoury custards such as those found in flan fillings, crème brûlées and crème caramels, both types of cream are called for in different recipes depending on how rich a result is called for. It is useful to note that double cream can also be thinned down with water to make an approximation of single cream if necessary.
Other items called "cream"
Many non-edible substances are called creams due merely to their consistency: shoe cream is runny, unlike waxy shoe polish; face cream is a cosmetic. There is generally no restriction on describing non-edible products as creams.
Regulations in many jurisdictions restrict the use of the word cream for foods. Words such as creme, kreme, creame, or whipped topping are often used for products which cannot legally be called cream. In some cases foods can be described as cream although they do not contain predominantly milk fats; for example in Britain "ice cream" does not have to be a dairy product (although it must be labelled "contains non-milk fat"), and salad cream is the customary name for a condiment that has been produced since the 1920s[10] and need contain no cream.
