An introduction

• What is your favorite kind of bread?

– Imagine you were stranded on a deserted island like Tom Hanks in “Castaway.” The Bread Fairy comes and tells you that you can have a pound of bread every day, but you have to pick only one kind. What would you pick?

• Were your two answers the same?

Bread Basics

• The oldest forms of bread center in Europe, the Middle East and Asia. They are mostly unleavened.

• Tortillas, pita, lavash, are unleavened. What do you think that means?

• They are flat.

• Leavened breads rise, and that gives them a lighter texture.

Bread Basics

• In France, there is a law that regulates what can be in bread if you are going to

call it French Bread.

• Flour, water, yeast, salt.

• Anything else goes in, you can’t call it French bread.

IngredientsAnd their

Functions


6

•Flour – gives the bread its

structure by the formation of gluten. Gluten strands are formed by proteins in the flour.

• Flour also provides starch which gives the body the nutrient, carbohydrates.

• So bread’s structure comes from proteins and starches.


7

•Yeast is a single-celled organism (a plant).

• When it has the right conditions it grows. Yes, your bread dough is alive in a certain sense. Yeast needs the right temperature (105F to 115F is best), food (it likes carbs like sugar and flour) and water.

• Yeast is killed by temperatures beginning at about 125F. • If you add very hot water to your yeast – it will be dead,

dead, dead and your bread won’t rise.• You can add the yeast to the dry ingredients and then use

water between 120 and 130F. The flour absorbs some of the heat and keeps the hotter water from killing your yeast.


8

•Water (or milk, or juice) –

hydrates the bread allowing gluten to form.

• It also dissolves things and thus allows salt, sugar and flavorings to be distributed throughout the dough.


9

•Salt – is a dough conditioner. It

strengthens and tightens gluten. • It also inhibits the growth of yeast. Without salt,

dough will over rise and then collapse. This can lead to bread with low volume (because the yeast has no food left to continue reproducing.)

• Lack of salt or too little salt can cause your bread to have a rough texture (especially on the top).

• If you bake it before the collapse, your bread can have too much volume and become a bread monster.

Bonus ingredients


11

•Fat – Butter, oil, shortening, lard.

– Fat is a tenderizing agent. Add fat to your baked good and it will be more tender.

– There is a limit. Too much fat and your baked good will just be greasy.

• The term for a dough with fat is short. Cookie dough is short; pizza dough is short. French bread is not short; bagels are not short, and neither are tortillas. These breads are called hard or lean.


12

•Sugar – Sugar is a tenderizing

agent.

– A dough can only hold a certain amount of sugar and still stay together.

– It also is a stealth liquid ingredient. Sugar liquefies when it gets wet or hot.
