Chapter 8—Converting Recipes, Yields, and Baking Formulas
TRUE/FALSE
1. Standardized recipes are ideal for food service operations such as nursing homes, retirement
villages, and some school cafeterias.
2. Baker’s percentage is the number that will be used to multiply the amount of the original
ingredients in a recipe to either increase or decrease a recipe.
3. When converting recipes to fewer portions, realize that the working factor will be less than
one.
4. Working factor is defined as the amount of portions, servings, or units that a particular
recipe or formula will produce.
5. The yield for recipes such as cake or muffin batters, roll or sweet doughs, pie filling, and
some cookie doughs, can be determined by taking the total weight of all ingredients used in
the preparation and dividing that figure by the weight of an individual portion or unit.
6. A working factor is defined as a relation in size, number, amount, or degree of one thing
compared to another.
7. Bakers use a simple yet versatile system designed to balance all formulas that feature flour
as the main ingredient. Each minor ingredient is a percentage of the main (flour) ingredient.
8. Keeping in mind that flour is the main ingredient, baker’s percentages designate the amount
of each ingredient that would be required if 10 pounds of flour were used.
