Part B: Fractions and Baking Directions: Ingredient measurements are often given as fractions in a recipe. When baking, it is important to be able to convert the recipe to change the number of servings so that there is enough for everyone. Suppose you are going to be serving two desserts for a party of 30 people.
1. For the first dessert, pick one of the cookie recipes below and convert the ingredient measurements so that 30 cookies can be made. (measurements should be in mixed number, not improper fractions, and reduced) Write out the new list of ingredients on the Fraction and Baking Worksheet. Be sure to include units.
* Sugar Cookies - 6 (3/4) cups flour
- 6 cups sugar
- 4 (1/2) teaspoons baking powder
- 2 (1/4) cups butter - 2 (1/4) teaspoons vanilla extract - 9 eggs
Makes 90 Cookies
* Chocolate Chip Cookies - 6 (1/4) cups flour - 3 (2/4) cups sugar - 1 (1/4) teaspoons salt - 2 (1/2) cups butter - 5 eggs
- 5 cups chocolate chips Makes 60 Cookies
