The document discusses baker's percentages, which is a method used by bakers to proportion ingredients in a recipe based on the weight of flour. It defines baker's percentages and explains why they are important for precision and scaling recipes up or down. The document also provides examples of converting recipes to baker's percentages and scaling up a recipe to make a larger batch.

- 2. What you will learn today Understand Baker’s Percentages Define baker's percentages. Why they are important. Several ways to use this tool. Math applications: Solve math conversion problems. Analyze formulas based on percentages. Lab Application: Develop a 1.5# loaf of bread to demonstrate what you learned in class,
- 3. Baker's percentage defined Each ingredient must be weighed Must convert volumes into weights Must have consistent units Weight of flour = 100%. Other ingredients expressed as % of flour
- 4. Why baker's percentages? Enables one to assess a formula quickly Enables formula modification Easy to scale a recipe up or down Precision (since weights are used) Provides a common language for bakers

- 17. Determining weights of ingredients (We want 20 pounds of dough) Start with the 100% ingredient: AP Flour: Total Yield Weight Total Percentage 20# divided by 170.3%= 11.74# 11.74 lbs. is the 100 % weight off which all other ingredients are based. Therefore, 11.74 will be our "factor" for calculating remaining ingredient weights.
