Chocolate is
made from
cocoa beans. It is the skill of the chocolate maker that creates the
fine chocolate from the cocoa beans that arrive from countries which
grow cocoa. Production techniques have undergone a lot of changes, as
the technology has advanced. But the process of making chocolates
remains the same. It involves roasting, grinding, refining, conching and
tempering. The secret of good chocolate lies in the expertise of the
maker, who should follow the process with care.
Roasting: The ultimate quality of
chocolate depends on the process of roasting and cocoa seed
fermentation. There are several roasting processes.
Pre - roasting: The beans are heated in infra red
radiant heaters to separate the nibs from the shells. They are roasted
at temperature from 100 degree C to 140 degree C (212 degree F to 300
degree F) for twenty to forty minutes.
Direct roasting: As an alternative the beans are
roasted and then shells are removed. This traditional method allows
retaining the flavour. The temperature for this process is maintained at
between 150 degree C and 160 degree C (300 degree F and 320 degree F)
for 40 to 50 minutes.
Even though both the methods are followed today, the
pre -roasting is more productive, but the problem is that some varieties
of beans get damaged when removed from shells due to severe temperature
fluctuations. The roasting is very important in the process of chocolate
making. The cocoa gets dried and become brown and develop the flavour,
thus completing the first stage of manufacturing.
The fermentation which is to be carried out earlier
enhances the flavour. It reduces the sugar, glucose, fructose and amino
acids. In fact it is the fermentation that brings the flavour and the
roasting process only augment the results of good fermentation. Proper
care should be taken to carry out fermentation. The possibilities of
beans getting spoiled are very high if the process is not carried out
carefully.
The quality of the chocolate will be superior if the
shells are removed thoroughly after or during the roasting. The process
of shelling includes milling, sifting, and winnowing. Each of the
process is important. When shelling completes the grains should be
uniform in size and there should not be any residual shells.
The roasted and crushed beans are milled to fine
flour. During the milling process, care should be taken to maintain the
required temperature to avoid smoky or burnt off flavours. The refining
converts the milled cocoa into a thick
liquid form
as cocoa butter.
Conching with powerful machines to stir the chocolate
to make it a homogeneous mixture must follow. This is done in two
stages. One is dry conching that is, stirring the chocolate at a
temperature of around 80 degree C (175 degree F) to get rid of any
residual moisture and to add viscosity.
Liquid conching is followed immediately after the dry
conching. It is done the same conch as a continuous process, to maintain
the texture and viscosity. Add
cocoa
butter if necessary. Tempering is a very delicate process of making
chocolate from the liquid or semi liquid to a solid form. The
chocolate
is then heated until the cocoa butter crystals have melted completely.
The product is then cooled to an appropriate temperature. The tempered
chocolate when perfected is a smooth, glossy and brittle product with
good flavour and tempting aroma.
The tasting chocolate involves skill. Those who enjoy
different flavours of chocolates can identify the origin of the beans
that are used in its making. Like coffee or wine, different people enjoy
chocolate according to their tastes. Chocolates should be kept at a
temperature of 66 degree F to 76 degree F to retain its taste and
flavour.
There are different types of chocolates, depending on
it filling. Some may be bitter or salty. Chocolates are made with the
following flavours. In plain chocolates there are flavours of cocoa,
pineapple, banana, passion fruit, vanilla, cinnamon or a blend of these.
In filled chocolates, all, the above aromas coupled
with the flavours of almond, pistachio, hazel nut, wall nut, honey and
fresh fruit are used. A tint of salt highlights the above flavours.
As for the texture, the chocolate should not leave
any grain on the tongue, when you taste it. The ingredients should be
grounded and blended to 12 to 20 microns. Plain and dark chocolate
tasting technique involves keeping it in you mouth for a few seconds, to
taste the base and primary flavours. Wait for a few seconds and chew it
for 5 to 10 times to enjoy the secondary flavours.
Keep the filled chocolate in your mouth until it
melts to release the base and primary flavours. Then chew for 4 to 5
times to blend the filling and coating and enjoy it. Finally, note how
long the flavour lingers on the tongue.
