Name That Utensil Serving spoons & cups vary in size. Only use these standard measuring utensils… Can you name them? ©2002 Learning Zone Express

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? 1 1/3 cups flour 1 1/2 teaspoons baking powder 1/2 cup milk 2 tablespoons cooking oil ©2002 Learning Zone Express

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. ©2002 Learning Zone Express

Measuring Dry Ingredients A standard set of dry/solid measuring cups is made of four cup sizes. What amount does each cup measure? ©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. 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. ©2002 Learning Zone Express

Pass the Cup Dry/solid measure check-up: 1/2 cup or 3/4 cup Which of these amounts is greater? Write the amount. 1/2 cup or 3/4 cup 1/4 cup or 1/3 cup 1/4 cup or 2 Tbsp. 1/2 cup or 1/4 cup 1/4 cup or 3 tsp. 1 1/3 cup or 1 1/4 cup ©2002 Learning Zone Express

And it shows how to measure those amounts with measuring spoons. 1 Tbsp. 1 tsp. + 1 tsp. + 1 tsp. 3/4 tsp. 1/4 tsp. + 1/4 tsp. + 1/4 tsp. or 1/2 tsp. + 1/4 tsp. 1/8 tsp. half of 1/4 tsp. 1/8 cup 1 Tbsp. + 1 Tbsp. ©2002 Learning Zone Express

Basic Equivalents Dry/Liquid equivalents: Equivalents are amounts that are equal to each other. They are useful when you must alter or change a recipe to serve more or less people than the recipe yields. Dry/Liquid equivalents: Pinch or Dash = less than 1/8 teaspoon 1 Tablespoon = 3 teaspoons 1/4 cup = 4 Tablespoons 1/3 cup = 5 Tablespoons & 1 teaspoon 1/2 cup = 8 Tablespoons 3/4 cup = 12 Tablespoons 1 cup = 16 Tablespoons ©2002 Learning Zone Express
