Temperature
Control
Time and temperature control is the key to successful baking. Before starting
with any baking process the baker checks the temperature of his/her working
conditions (room temperature), calibrates the oven and refrigerator and keeps
constant watch on the batter or dough. The temperature of the ingredients,
when added, affects the mix speed and time. Cold ingredients increase the
mix time, while warm ingredients reduce it. Further, dough or batter at high
temperature leads to large holes in the finished product. A kitchen thermometer
and a timer are great tools to control temperature and regulate time.
Measuring
The first step in baking is accurately measuring the ingredients. Double-check
the recipe for measurement interpretation. e.g. whether teaspoon is heaped
or level. Convert the units from pounds to kilograms or vice versa, depending
on which you are using (1 kg = 2.2 lbs). Similarly convert gallons to liters
or vice-versa (1 liter = 0.265 gal.). Do not work with approximations, use
the tools for measuring: weighing scale (digital or manual), cups (metal or
plastic) and spoons (metal or plastic). When measuring dry ingredients ensure
that the container is dry. When using a scale weigh the ingredients separately
or return the display to zero before taking the next ingredient.
Mixing
The process of uniform blending of the individual ingredients that make up
the dough or the batter. Mixing can be done manually or with tools and gadgets.
Manual mixing is cumbersome, tiresome and time consuming. Utilize modern means
for convenience and better results: whisk, mixer (hand or stand) or food processor.
Depending on the kind of product, mixing can have different objectives:
In Bread Dough: The target of mixing is to bring
about the physical development of the gluten (protein) in the dough, into
a uniform structure with desired plasticity, elasticity and viscous flow.
For good volume, shape and crumb-texture of bread, dough should be carefully
mixed. Appropriately mixed dough is soft and smooth with good elasticity.
Under-mixed dough is lumpy or cloudy and breaks or separates on pulling a
little. Over-mixed dough breaks down and becomes very fluid and sticky.
In Pastry Dough: The target of mixing is to bring
the ingredients together into dough mass. For flaky, crunchy and tender pastry,
mix the dough for a very short time. Appropriately mixed dough is cold, stiff
and breaks easily. Under-mixed ingredients will remain pea size crumbs. Over-mixed
dough will attain elasticity and higher temperature.
In Cake Batter: The target of mixing is not only
to attain a thorough and uniform dispersion, but also to incorporate air into
the batter. For a good sponge, volume and mouth feel the batter should be
smooth with a good flow. Under-mixed batter has lumps and is cloudy. While,
over-mixed batter breaks down and becomes very fluid.
Second
Mix
Many times ingredients are mixed in two stages. This is done to enhance the
fermentation flavor and allow appropriate hydration time to ingredients. After
the first mix, the dough is allowed to rest or ferment and then the other
half of the recipe is added. Two-stage mixing is a popular method in making
breads.
Proofing
The process of fermentation in yeast-raised dough such as for breads. Fermentation
affects the volume, flavor and aroma of the baked products. Optimum development
of yeast in minimum time occurs under appropriate proofing conditions, which
include warm temperature (85-90°F or 29-35°C) and high humidity. During
fermentation, yeast gives out carbon dioxide and alcohol. Carbon dioxide gets
trapped in the dough mass thereby contributing to the volume of the bread.
Alcohol increases acidity in the dough and contributes to flavor and aroma.
1-2 hours of proof-time is normally sufficient, however when the volume of
the dough doubles, it is ready for further processing.
Note: Proofing can be either before Molding or after Molding.
Second
Proof
Second proof is the same as the first proof, with the difference that after
the second the product is ready to be baked. Providing a second proof depends
on the fermentation flavor desired. Second proof is normally for breads after
molding or shaping the bread. Once the bread attains 10% less than the desired
volume of a finished loaf, it is ready to be processed further.
Retarding
(Refrigerating)
The process of slowing down maturing or aging of perishable items such as
fruits, flowers etc by reducing the temperature, generally in the range of
35-42°F or 2-5°C. In the context of baking, retarding plays a vital
role in attaining desired dough characteristics. In pastry dough, retarding
provides time to the ingredients to hydrate and relax. Pastry dough is retarded
for at least 30 minutes, to obtain flaky and tender characteristics. In bread
dough, retarding reduces the rate of fermentation, which influences the flavor,
aroma and appearance of the finished stuff. Bread dough is retarded for 8-10
hours or overnight to attain the desired volume.
Molding
(Shaping)
Molding is the process of forming the dough or batter into the desired shape
of the finished product. Normally dough has the ability to hold its shape.
Molding of most dough products flows in the following order;
1. Dividing the dough: This is done to create
desired portions.
2. Rounding into a smooth surface ball: Rounding
is done by rolling the dough piece between the palms or on a smooth surface.
Any cracks or crevices on the dough ball affect the appearance of the finished
product. The dough ball should be well rounded with a smooth surface. To prevent
the dough from sticking, some flour is used for dusting.
3. Intermediate proof: Intermediate proof is
the process of providing a relax time of 10-15 minutes to the dough, to recover
from the abuse of dividing and rounding.
4.
Sheeting or rolling:
This is done to equally distribute the air cells trapped in the dough. The
dough ball is rolled out into a flat disc on a clean smooth surface, with
the help of a rolling pin or pressure board or by hand. To prevent the dough
from sticking, some flour is used for dusting. In forming pastry dough or
pizza base, this may be the final step in molding.
5. Final Folds: Any excess flour is dusted off
from the sheeted dough and then folded to obtain the final shape of the product.
The most popular ways of molding batter products are:
a. The batter is poured into molds or pans and placed in the oven, as done
for cakes. In this case the batter is relatively fluid and acquires the shape
of the mold.
b. The batter is filled in a pastry bag and squeezed out into desired shape.
Preparing
to bake
Before the bread, muffin, cookie or tart go into the oven, they are prepared
for baking to either improve eating qualities or to enhance the appearance.
Depending on the product, preparation may include:
Filling with compote or custard,
Topping with fruits or nuts or seeds,
Spraying or brushing with egg wash or milk for shine,
Spraying or brushing water to get a tough and chewy crust,
Docking (scoring) to create passages for steam release,
Dusting flour or cocoa or coffee for a rustic look
Baking
Baking is the process of convection cooking in a hot chamber. During the process
of baking, many physical and biochemical changes occur in the dough; the starch
in the flour gelatinizes, sugar caramelizes, water evaporates and the product
gains volume, texture, flavor and appearance. Temperature and time for baking
is specific to each product and changes with many factors. Steam is often
used during baking bread & rolls to obtain a shiny and chewy crust. At
the domestic level steam is generated by keeping a pan of boiling water in
the hot oven when baking the bread or roll.
Cooling
The process of cooling sets the structure of the baked product and makes it
easy to handle and consume. Products are cooled at room temperature at normal
humidity level. If the humidity is high, the product loses its crunch, while
if the humidity is low; the product loses the desired moisture. Cooling time
differs depending on the size and kind of the product.
Finishing
(Icing)
Once the goodies are baked and cooled, finishing touches are added to them
to enhance flavor, appearance and extend the shelf life. While in some flat
and savory breads, the only finishing touch may be to smear oil or butter
to add flavor and moisture for better keeping qualities, finishing is an essential
process in most sweet goods which are glazed, chocolate-coated or iced for
attractive appearance and flavor.
Storing
Most bread products are stored in air-tight containers at room-temperature.
Some short-life bread & rolls with a chewy crust are stored in paper or
perforated bags, which allow air ventilation to maintain the crunch in the
crust.
Sweet goods, especially those with perishable fruits and cream decoration,
are stored in a covered jar at cool temperature.
