Quickbreads Flashcards
A quick bread is different then yeast dough in that
quick breads are made with chemical leavening agents instead of yeast which requires time for fermentation and proofing
Chemical leavening agents help a product rise by
releasing a gas ( carbon dioxide),
form by chemical reaction, between acids and bases, contained in the recipe, gases form air bubbles/ pockets
Product bakes gases expand
Rise
Proteins set around air pockets giving bread its texture and rise
Single acting baking soda
requires only moisture to release gas
(eggs, milk, water, or other liquids)
Single acting, bake immediately
Double acting baking soda
Popular
small release of gas on contact with moisture
Second stronger release of gas when heat is applied
Can sit without losing ability
Baking soda and powder in same recipe
baking soda only realses as much CO2 as acid, powder can be added to increase leavening
Baking soda
Makeup: Sodium bicarbonate
Reactants: if both moisture and acid are present, the product is CO2 ( Heat not necessary)
Baked at once
Acids for baking soda(buttermilk, sour cream, lemon juice honey, molasses, citrus fruits )
Baking soda= acid ( too much and the product will be soapy or bitter, yellow color, brown spots
Baking powder
Makeup: sodium bicarbonate + acids (cream of tartar/ sodium aluminum sulfate)
Contains starch to balance chemical reaction and prevent lumping
No extra acid needed only moisture
Can sit
Purchasing and storing chemical leavening agents
Smallest unit appropriate for operation
Large units have a chance of deteriorating and wasting product
Tightly covered, in a cool place
What is baking ammonia used for
Cookies and crackers
Why isn’t baking ammonia used in quick bread
Because of its noxious scent
difference between scones and biscuit
scones use butter and eggs and cream
3 methods quick breads are mixed in
Muffin method
Biscuit method
Creaming method
Biscuit method
Fat- solid (chilled)
Result- Flaky dough
Muffin Method
Fat- liquid ( oil or melted butter)
Result- soft tender cake like texture
Creaming method
Fat- softened( room temperature)
Result- rich tender cake like texture
