Running head: QUICK BREADS
Quick Breads Lab Report

Introduction
There are many types of quick breads, but one thing that they all have in common is that
they use carbon dioxide to leaven them. This is accomplished by using either baking soda or
baking powder. In this report, we will explore how they react in biscuits. Most biscuits use a
special mixing method which involves cutting the fat into the dry ingredients and then adding the
wet ingredients. The exception is Whipping Cream biscuits because no solid fat is used. They are
prepared using the Conventional mixing method where the liquid is poured over the dry
ingredients and then mixed. This is because self-rising flour already contains baking powder and
the whipping cream is both the liquid and the fat. Because of the differences in mixing methods
and the type of flour used this lab report explores these two types of biscuits to see how these
differences affect the finished biscuits.
Materials and Methods
BASIC BISCUIT RECIPE
The ingredients used to make the basic biscuits were: 2 cups all-purpose flour, 3/4

teaspoon salt, 1 tablespoon double-acting baking powder, 5 tablespoons cold butter and 2/3–3/4
cup milk (approximate). Other tools used were a medium sized mixing bowl, a
fork, a pastry blender, a large cutting board, a rolling pin, a biscuit cutter,
parchment paper and a baking sheet. These biscuits were prepared as
follows: the oven was preheated to 425 degrees. The flour, salt and baking
powder were sifted together in a medium-sized mixing bowl. The butter was
cut into the flour using a pastry blender until it resembled coarse cornmeal.
The milk was then added and stirred with a fork until they came together.
The dough was then turned onto a lightly floured surface and kneaded just
until the dough was smooth. The dough was then rolled out on a cutting
board to ½ inch thickness. Next it was cut with a flour biscuit cutter and
placed onto a parchment paper covered baking sheet. In the final step, it
was baked at 425 degrees for 11 minutes.
WHIPPING CREAM BISCUITS
The only ingredients required to make whipping cream biscuits are: 2 cups
self-rising all-purpose flour or soft wheat flour and 1 cup heavy or whipping
cream. All-purpose self-rising flour was used for the biscuits that were
prepared for this lab report. Other tools used were a medium sized mixing
bowl, a fork, a large cutting board, a rolling pin, a biscuit cutter, parchment
paper and a baking sheet. These biscuits were prepared as follows: the oven
was preheated to 450 degrees. The flour was placed in a medium-sized

mixing bowl and the whipping cream was added. The ingredients were
stirred with a fork until soft dough was form. The dough was then turned
onto a lightly floured cutting board and kneaded until it was smooth. It was
then rolled to a ½ inch thickness and cut with a floured biscuit cutter. The
cut biscuits were then placed on a baking sheet lined with parchment paper
and baked at 450 degrees for 11 minutes.

Discussion
The method used for mixing biscuits is called the biscuit method. In the
biscuit method the fat is cut into the dry ingredients and then the wet
ingredients are added and mixed lightly until a soft dough forms. Muffins are
made using the muffin method. In this method all the liquid ingredients are
added all at once to the dry ingredients (Bennnion & Scheule, 2010).
If biscuits are over-kneaded they become tough and hard like hockey
pucks. This is because the baking soda goes to work just as soon as the
dough gets wet. Biscuits should be mixed just until all the ingredients are
incorporated. A really light touch is needed to make good biscuits (boar_d_laze,
2009).
Baking soda is used when making buttermilk biscuits because the
buttermilk is acidic. Baking powder contains baking soda, salt and an acid. A
quick bread requires all three of these ingredients in order for the CO2 to
leaven the product (Bennnion & Scheule, 2010).
When you mix baking soda with an acid and a liquid it reacts producing
carbon dioxide gas which causes the product to increase in volume
(Bennnion & Scheule, 2010).
The reaction of double-acting baking powder is similar to baking soda
except that it already contains the acid. It reacts the same way as baking
soda on the dough but it is double acting because it also contains another

acid which reacts with heat producing more carbon dioxide gas during
baking (Bennnion & Scheule, 2010).
Another quick bread product that is prepared using the biscuit method is
scones.
