bread Flashcards
Bread is made of what?
made of flour, water and yeast, or other leavening agents, mixed together and baked.
What is the nutritionally important source of bread? And give some examples
It is an important source of carbohydrates. If whole grain: it contains fibre, iron, magnesium, thiamin, riboflavin, niacin. White bread is often enriched with iron, folic acid, riboflavin, niacin, thiamin
What are some pivotal developments in bread’s evolution?
Leavening, milling and mechanical slicing
What is leavening?
Allowed for bread to rise, requires a leavening agent (something that will cause to expand)
What is milling?
Allowed for refinement of grains, softer and more uniform loaves
When did mechanical slicing become popular?
1928
Give 3 examples of common leavening agents
yeast, baking soda and baking powder
Explain what is yeast made from and what activates it
Yeast is a single-cell organism (saccharomyces cerevisae). It requires a fuel source (sugar, flour) and liquid to be activated
Explain what it contains baking soda and what activates it
it contains sodium bicarbonate, it requires acid and liquid to be activated
What pastry can you do with baking soda
cakes
Explain what it contains baking powder and what activates it
contains sodium bicarbonate and a weak acid, requires liquid to be activated
What pastry can you do with baking powder
cake (it is like baking soda but with an acid)
Why leavening agents is important and what it makes their importance
Because the produce makes CO2, so that causes the bread and the other products to rise.
why do live yeast cells leavening will be killed during cooking?
because if the water is higher than 55 degrees - kill it
if water is below 20 degrees - no fermentation. So water needs to be warm to activate yeast
How can we proof yeast?
activate dry yeast in warm water before adding it to the dough mixture
What are the 3 common types of yeast?
- active dry yeast
- instant yeast
- rapid-rise yeast
Explain active dry yeast
encapsulated live yeast with growth medium
need proofing for activation
very sensitive to thermal shock
Explain instant yeast
like activate dry yeast but a higher percentage of live yeast cells
does NOT need proofing, add to the dry mix directly
Explain rapid rise yeast
smaller granular size of yeast allows the dough to rise faster
a form of instant yeast, add to the dry mix directly
What are some forms of cooking methods for bread
- baked - traditional oven, brick oven, tandoor oven
- grilled - over a fire/directly on hot coals
- steamed (vapeur) - steam baskets
- fried - in a pan
- griddled
What are the basic steps to make unleavened bread?
1) mix ingredients together
2) leave to ferment (not always)
3) portion dough or batter
4) cook
What are the basic steps to make leavened bread?
1) mix ingredients together - activating the yeast
2) knead the dough - encouraging gluten formation
3) first rise - allowing CO2 to form
4) punch down- removing air pockets
5) portion, round, shape
6) proof/ second rise - allowing CO2 to form
7) bake
Pain ménage/ white loaf is made with what? And is leavened with what?
Made with wheat, leavened with yeast
Pain ménage/ white is a bread from where?
North America
