What’s an Abbreviation?
 Understanding the language of recipes takes
the guesswork out of cooking.
 Abbreviation - The shortened form of a word.
 Abbreviations in measuring units:
• Save space on the cookbook page.
• Make recipes easier to read.

The Right Measuring Utensil
 What are two ingredients that
you’d measure with when using:
• measuring spoons?
• dry/solid measuring cups?
• a liquid measuring cup?
 Which measuring utensil would you use to
measure each of these ingredients?
•
•
•
•
13
1 1/3 cups flour
1 1/2 teaspoons baking powder
1/2 cup milk
2 tablespoons cooking oil

Measuring Liquid Ingredients
 Liquid ingredients can include:
• Milk, water, oil, juice, vanilla extract, etc.
 To measure 1/4 cup or more of a
liquid ingredient, use a clear, liquid
measuring cup.
• Place the cup on level surface and read measurements at eye level.
 For smaller amounts use measuring spoons.
• Fill the spoon until a slight dome is visible.
14

Measuring Dry Ingredients
 A standard set of dry/solid measuring cups is
made of four cup sizes.
 What amount does each cup measure?
15
©2002 Learning Zone Express
Measuring Dry Ingredients
 Dry ingredients can include:
• Flour, sugar, brown sugar, salt, and baking powder.
 To measure 1/4 cup or more of a
dry ingredient use a measuring cup.
• Measuring cups generally come
in 1/4, 1/3, 1/2, and 1 cup sizes.
 To measure less than a 1/4 cup
use a measuring spoon.
16
• Measuring spoons generally come in
1/4, 1/2, & 1 teaspoon & 1 tablespoon sizes.
• To measure 1/8 tsp. measure 1/4 tsp.
& then remove half.
©2002 Learning Zone Express
Measuring Dry Ingredients
 Measuring flour:
• Do not pack the flour into the
measuring cup or spoon because you will
end up with more flour. Instead, scoop flour
into the cup and level with a spatula or knife.
 Measuring brown sugar:
• Pack the brown sugar tightly into the measuring cup or spoon.
Once it is packed down, level it with a straight edge or knife.
 Measuring granulated sugar:
• Fill the cup with sugar. Level with the back of a spatula or knife
so that sugar is even with top of measuring cup or spoon.
17

Pass the Cup
 Dry/solid measure check-up:
• Which of these amounts is greater? Write the amount.

 Sticks of butter and margarine
have measurements marked
on the wrapper.
• One stick = 1/2 cup or 8 tablespoons
 Measure solid fats, such as shortening or
peanut butter, in a dry measuring cup.

Applying What You Know
Choose one of the following assignments to complete outside of class.
 Create a worksheet of math word problems based on
kitchen measurements. Be sure to create an answer
sheet. Trade worksheets with a classmate and grade
each other’s work.
 Create new recipe cards that double and cut in half a
favorite recipe. For extra credit make the recipe and
evaluate the results.
 Create an easy-to-read poster of common
abbreviations and basic equivalents. Be sure to
include visuals and display accurate information.
38
