1. March 11, 2013  Entry task: What do you think a leavening agent is? What function does a leavening agent play in baking?  Target: To identify the role and function of various leavening agents when baking.

4. This week:  Tuesday - Cupcake lab prep  Wednesday – Cupcake bake and test  Thursday- Worksheet  Friday-Leavening agent QUIZ

5. Class Target: To understand the role and function of various leavening agents when baking.

6. Leavening Agents  There are two main types of Leavening Agents used in baking. Yeast & Chemicals.  Yeast is a microorganism that feeds on sugars, creates gas, and pushes out on the surrounding dough to make it rise.  Chemical leavening agents do the same thing with a chemical reaction. The basic reaction is  ACID + BASE = A GAS (CO2)

7. How the reaction works:

8. Examples of Acids & Bases AcidsBases VinegarBaking Soda Buttermilk Cream of Tartar (not tarter sauce) Baking Powder = Baking Soda + Cream of Tartar

9. The Acid and Base react to create bubbles in the dough! The experiment that we are going to do on Wednesday is designed to show you how various leavening agents work in the baking process. Follow the directions on the lab, using the appropriate leavening agent assigned to your kitchen group. When done arrange on a plate leaving one whole, one cut in half and the others cut into bite sized pieces for the class to evaluate. Make sure there are enough for each person to try. Please do not take more than one!

10. Quiz  You will have a quiz on leavening agents on Friday! Listen up! Study hard and ask questions.

11. Fill Out Lab Plan Form  Take this time in class to fill out your lab plan form correctly.  Turn it in to me when finished.  You will have 5-10 minutes.

12. Predictions  Make predictions on the turnout of the cupcakes depending on their leavening agent or lack of.  You will receive points for doing so.

13. Flash Cards  In order for you to do well on your final, you will make flashcards in class to study.  You will have several foods quizzes that count for points throughout the semester  Study in chunks. DON’T LEAVE UNTIL THE LAST MINUTE!!!
