Cream
From Wikibooks, the
open-content textbooks collection
Cream
is a dairy product that is composed of the higher-fat
layer skimmed from the top of raw milk before
homogenization. In the raw milk, over time, the lighter
fat rises to the top. In many countries cream is sold in
several grades depending on total fat content.
Cream produced by cows
grazing on natural pasture often contains some natural
pigments; this gives the cream a slight yellow tone. Cream
from cows fed on grain or grain-based pellets, is white.
In the US, cream is
usually sold as:
- Half-and-half (12%
fat)
- Whipping cream and
whipped cream (30%)
- Heavy cream, or heavy
whipping cream (36%)
- Manufacturer's cream
(40%), mostly available from food-services supply
wholesalers rather than grocery stores
Also common in the US is
sour cream, which is cream that has been fermented with
lactic acid bacteria. This produces a sour taste and
thickens the cream.
In the UK, cream is
usually sold as:
- Half cream (12%)
- Single cream or Light
cream (18%)
- Whipping cream (35%)
- Double cream (48%)
In the UK, clotted
cream is a very high fat (55%) product processed with
heat.
Crème fraîche (a
product with a French name and widely available elsewhere)
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.
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. If the
whipping is continued, the fat droplets stick together and
form butter;
the remaining liquid is buttermilk.
Cream is the principal
constituent of butter.
Ice cream is made with
milk, milk proteins, cream and flavorings, frozen while
stirring to limit the size of the ice crystals. Premium
ice creams usually contain more milk fat.
The term cream or crème
is also used to refer to a variety of substances of a
consistency similar to or thicker than that of cream, such
as chocolate cream or coconut cream.
