YEAST BREADS
Mrs. Halverson
Things to Know about Leavening• Yeast breads use YEAST as a leavening agent.
• Yeast needs warmth, food and moisture to
grow.
• Small amounts of sugar speeds the activity of
yeast. (too much sugar will inhibit yeast
activity)
• Salt inhibits the speed of yeast activity.
YEAST BREADS
Temperature and yeast
• 50 degrees- yeast begins to activate
• 78-82 degrees- yeast produces the most gas
• 120 degrees- yeast begins to die
• 143 degrees- yeast is useless for baking.
KNEADING DOUGH
• Kneading dough develops gluten to give the dough shape
and structure.
• Gluten is a protein in flour.
– You only want to stir/mix quick breads a little to
form a small amount of gluten
– You want to stir/mix (knead) yeast breads a lot to
form a large amount of gluten.
Kneading Dough- continued
• You may knead bread by hand or with your
dough hook on the electric mixer.

YEAST BREAD BAKING BASICS
On a piece of paper in your binder/notebook,
answer the following questions for review:

7. How do I know if a loaf of bread is done?
YEAST BREAD BAKING BASICS
ANSWERS
1. Why is it important for the water to be the
correct temperature to mix yeast?
- Yeast is a living organism and if the water is too hot
it will kill the yeast and the dough will not rise.
2. What do fats do in yeast breads?
- Fats make breads soft and tender.
3. Name 2 types of flour available for making
bread?
– Rye, soy, whole wheat, rice, all-purpose, bread flour.
4. What does kneading do for the bread?
– It forms gluten. It makes the dough smooth and
elastic.
5. How can you tell if you have kneaded bread
long enough?
- When an indentation in the center of the bread
stays in place. It is smooth and elastic.
6. What purpose does sugar serve to yeast
bread?
- Sugar acts as food for the yeast.
7. How do I know if a loaf of bread is done?
-When you knock on the loaf it sounds hollow.
