Batters & Doughs (flour mixtures) include:
Definition
Muffins, biscuits, & other quick breads
Pastries
Shortened & unshortened cakes
Cookies Breads
Term
Basic ingredients of batters & doughs
Definition
Flour
Leavening Agent
Fat
Liquids (milk, water)
Eggs (protein & binding)
Sugar & other sweeteners
Term
Use of sugar in batters & doughs
Definition
Taste
Carmelization
Inhibits moisture (until internal temp. can't hold moisture, then causes bread to rise)
Term
Flour
Definition
Most in US made from wheat (gluten gives structure)
Milling is the separation of endosperm from bran & germ
Grades of flour are by size
1. patent: smallest
2. straight: all purpose
3. clear: largest
Term
Enrichment of flour
Definition
Nutrients added:
1. B vitamins (thiamine, riboflavin, niacin, folic acid)
2. Iron
3. Vitamin D & Calcium are optional (fat soluble)
Term
Proteins in flour
Definition
Insoluble gliadin & glutenin, which form gluten when moistened, then kneaded. Gluten is responsible for the viscous & elastic characteristics & high loaf volume of wheat flour doughs. Glutenin + Gliadin + water + work = gluten *Gliadin is generally missing in gluten-free foods
Term
Gluten formation
Definition
Hydrate a wheat flour mixture with water then mix to form gluten

* over mixed dough is chewy, hard, dense (gluten strands may tear)
* too much water interferes with gluten development
Term
Types of wheat flour
Definition
Bread (makes cakes turn out hard & dense)
all purpose
pastry
cake
self-rising (already includes baking soda & salt)
gluten (18% protein)
Term
Flours & meals (not wheat)
Definition
1. rye (less gluten forming properties)
2. cornmeal & corn flour (chief protein is zein, need to combine with flour)
3. soy flour (high in protein, low in gluten)
Term
Leavening
Definition
To Leaven- to make light & porous
Major leavening gases: air, steam, carbon dioxide
Term
Leavening gases: Air
Definition
Incorporated by:
Beating eggs
Creaming fat & sugar
Beating butter
Folding or rolling dough
Term
Leavening gases: steam
Definition
High liquid content & high oven temperature
(cream puffs & popovers)
Term
Leavening gases: Carbon dioxide
Definition
Added by:
1. Action of yeast (fermentation)- CO2 is produced by yeast and certain bacteria with sugar
2. Chemical production:
Baking soda & baking powder- chemical leaveners that produce an acid/base reaction to give off CO2 in the presence of moisture.
Term
Baking soda
Definition
Sodium bicarbonate

Gives off CO2
Used in recipes with an acid ingredient (buttermilk, vinegar, cream of tartar)
Term
Fat in flour mixtures
Definition
Role is to tenderize or shorten the gluten strands.
Emulsifiers allow fat to be evenly dispersed throughout the batter.
Butter & margarine are about 82% fat.
Shortened breads have "shorter" air cells.
Term
Eggs in flour mixtures
Definition
Incorporate air into batter
Yolks add flavor & color
Form emulsions
Increase rigidity upon baking (egg proteins coagulated when heated)
Term
Sugar in flour mixtures
Definition
Sweetening
Tenderizing
Moisture retention
Contributes to browning
Aids in leavening (creaming of fat & sugar, stabilize egg white foams, provides food for yeast)
Term
Batters vs. Doughs
Definition
Batters: pour or drop batters (more liquid)
Yeast batters are called sponge.
Doughs: thick enough to be handled
Term
Mixing methods
Definition
1. Muffin: most quick breads, boxed cakes (all dries, then liquids, little stirring)
2. Pastry or biscuit (cut in fat)
3. Conventional (creaming fat with sugar, add eggs, add dry ingredients alternatively with liquids)
4. Conventional sponge (cream fat w/ half cup sugar, half cup sugar beaten w/ eggs & reserved, add dry ingredients alternatively w/ liquids, fold in egg & sugar mixture)
5. Quick mix (higher proportion of sugar & liquid, sift dry ingredients, add all fat & part liquid, add eggs & remaining liquid)
Term
Baking at high altitudes
Definition
Atmospheric pressure is less (greater rise)
* less resistance for leavening gases & greater expansion
* moisture evaporates quickly
* water & liquids boil at lower temp.
Term
Popovers (quick bread)
Definition
High proportion of liquid
Produces steam for leavening
Prevents excess gluten development

Usually baked in hot oven (450°F)
Reduce temperature after 15 minutes

Structure usually because of
* Gelatinization of starch
* Coagulation of eggs

Browning because of
* Maillard reaction
* Dextrinization of starch

Failure usually because of under baking
Term
Cream Puffs and Eclairs (quick bread)
Definition
Cream puff batter also called pâte à choux.

Like popovers
* High liquid

Unlike popovers
* High fat
* High eggs
(Eggs helps to emulsify the fat)

Causes of failure
* Excessive evaporation of moisture
* Usually when heating fat and water range top
* Insufficient baking
* Under baked puffs and éclairs may collapse
* Insufficient beating of mixture
* Inaccurate ingredient measurements
Term
Waffles
Definition
Waffle batter similar to pancake batter except
* More eggs
* More fat

Usually leavened by baking powder although some recipes use yeast

Cook on a preheated waffle iron
Term
Pancakes
Definition
Typical ingredients
* Flour, liquid, baking powder or soda, salt, and egg
Variations are possible
* Adjust how thick or how thin by amount of liquid in relation to flour

Mixing
* Do not over mix
* Batter should be lumpy
* Over mixed pancakes may be soggy, show tunnel formation, and be tough
Term
Muffins
Definition
Characteristics
* Pebbly – not smooth peaked top
* Crumb is slightly moist, light and tender
* Should break without crumbling

Mixing – Use Muffin Method
* Fat melted or use oil
* Combine fat with other liquid ingredients (egg and milk)
* Mix all dry ingredients together (flour, leavening, salt)
* Pour liquid into dry ingredients and mix lightly
* Batter should be lumpy – NOT smooth

Over mixed muffins
* Have peaks and tunnels
Term
Biscuits
Definition
Mixing – Biscuit/Pastry Method
* Cut solid fat into the flour
* Add milk and stir briefly
* Knead lightly
* Roll out and cut

Drop biscuits contain more moisture and are not kneaded

Bake in hot oven (425° – 450°F)
Term
Scones
Definition
Similar to biscuits but richer
Contain eggs, butter, half and half or cream with flour, leavening, and salt.

Use biscuit method to mix
Bake on ungreased baking sheet
Term

*Starters or sponge
Term
Types of flour in yeast breads
Definition
Bread flour preferable
A high protein flour made from hard wheat

Whole wheat flour
Bran in whole wheat will interfere with gluten development

Rye flour
Usually mixed with wheat flour for better gluten development
Term
Sugar in yeast bread
Definition
Not an essential ingredient in yeast breads

Sugar functions
Increases rate of fermentation

Term
Kneading yeast breads
Definition
Essential for development of strong elastic gluten strands

Methods
Kneading by hand
Kneading by machine

During kneading manage amount of flour used
Dough should be soft but not sticky
Too much flour = dry, stiff dough
Term
Fermentation
Definition
Time between start of mixing and molding or shaping of dough

Fermentation reaction
Glucose + Yeast = Ethanol + Carbon Dioxide

Favorable conditions
Moist, warm environment

When dough has doubled in size
Punch down and allow to rise a second time or shape into rolls or loaves

If allowed to ferment too long
Poor oven spring
Flat or sunken top
Coarse grain and thick cell walls
Unpleasant sour odor
Crust may brown poorly

Inadequate fermentation
Thick cell walls
Heavy and small volume
Less tender
Term

Crumbly texture
Development of leathery crust

Occurs more quickly if refrigerated
Store at room temperature or freeze
Warming can reverse effects of staling


To large extent - caused by retrogradation of amylopectin
Term
Types of cakes
Definition
Shortened (fat)
Unshortened (no fat)
Chiffon (a blend)
Term
Shortened cakes
Definition
Pound cakes:
* tender
* compact & close grain
* historically, 1 pound each of butter, sugar, flour, & eggs
* no leavening agent (leavened by air & steam)

Standard shortened cakes:
* fine grain
* uniform cells w/ thin cell walls
* elastic crumb
Term
Sugar in cakes
Definition
* adds sweetness
* promotes tenderness by interfering with gluten development
* influences volume (traps air during creaming, raises starch gelatinization temp)
Term
Fat in shortened cakes
Definition
* often includes shortening, butter, & margarine
* increases tenderness
* increases volume by (decreasing cohesive forces, adding air during creaming)
Term
Why use cream as fat in shortened cakes?
Definition
So sugar can't absorb liquid until temperature gets higher, then releases to help with leavening.
Term
Emulsifiers in shortened cakes
Definition
Allow fat to be distributed more finely and more sugars may be incorporated.

* high ratio in shortenings
* decrease cohesive forces thereby increasing volume
* mono & diglycerides
Term
Flour in cakes
Definition
Contributes to structure

Too little flour: weak structure & coarse texture, cake may fall

Too much flour: compact, dry cake
Term
Liquid in cakes
Definition
Milk, water, & fruit juices

* dissolves ingredients
* hydrates starch & protein
* produces steam
* if excess liquid, poor volume
Term
Over & undermixing of cakes
Definition
Overmixing:
* may toughen cakes, especially if lean mixture or high protein flour used
* compact cake
* heavy or soggy

Undermixing:
* coarse texture
* thick cell walls
* concave surface especially if a rich mixture
Term
Unshortened cakes
Definition
Do not include shortening or other types of added fat

* angel food (egg whites only)
* yellow sponge (whole egg)

* pans are not greased
* baking temp 350-375 for 20-25 min
