1 Kitchen Math & Measurements

2 ©2002 Learning Zone Express2 Quesadillas (Serves 4 - 2 per person) 8 flour tortillas 1 cup grated cheese 1.Heat a frying pan over medium heat. 1.Place a tortilla in the pan. 2.Sprinkle 1/4 cup cheese on the tortilla. 3.Cover the cheese with another tortilla. 4.Cook about 1 minute, until brown and crisp. Then turn the quesadilla over. Cook until the cheese melts. 5.Place on a serving plate. Cut into pie shaped wedges. 6.Repeat process with remaining ingredients. Parts of a Recipe A recipe usually includes: Name What the recipe is called. Ingredients Food products you need to make the recipe. Yield Number of servings the recipe makes. Directions Steps you follow to make the recipe. Equipment

3 ©2002 Learning Zone Express3 Name the Abbreviations The U.S. uses the English system: –Teaspoontsp. or t. –TablespoonTbsp. or T. –Cupc. –Pintpt. –Quartqt. –Gallongal. –Ounce/fluid ounce oz./ fl. oz. –Poundlb.

4 ©2002 Learning Zone Express4 Name the Abbreviations Most other countries use the Metric system: –Milliliterml –LiterL –Gramsg –Kilogramkg

5 ©2002 Learning Zone Express5 Name the Abbreviations More abbreviations: –Few grains, dash, pinchf.g. –Dozendoz. –Poundlb. –Inchin. –Secondsec. –Minutemin. –Hourhr. –Degree  –Fahrenheit/CelsiusF. / C

6 ©2002 Learning Zone Express6 Abbreviations Pop Quiz What do these stand for? –lb. –L–L –tsp. or t. –  F. –qt. –fl. oz.

7 ©2002 Learning Zone Express7 Pass the Cup Dry/solid measure check-up: –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 or2 Tbsp. 1/2 cupor 1/4 cup 1/4 cup or 3 tsp. 1 1/3 cupor1 1/4 cup

8 ©2002 Learning Zone Express8 Measuring Just With Spoons This chart shows some amounts that you’ll often see in recipes. 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 cup1 Tbsp. + 1 Tbsp.

9 9 Basic 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

10 ©2002 Learning Zone Express10 Basic Equivalents To help you remember: 1 Tablespoon = 3 t e a spoons There are 3 letters in the word tea and 3 teaspoons in a tablespoon. 1/4 c. = 4 Tbsp.

11 ©2002 Learning Zone Express11 1 pint = 2 cups 1 quart = 2 pints = 4 cups 1 gallon = 4 quarts = 8 pints = 16 cups Basic Equivalents 1 fluid ounce = 2 Tablespoons 8 ounces = 1 cup 16 ounces = 1 pound

12 ©2002 Learning Zone Express12 Basic Equivalents To help you remember: A formula 2 c. = 1 pt. 2 pt. = 1 qt. 4 qt. = 1 gal.

13 ©2002 Learning Zone Express13 Equivalents at the Store At the store, many foods are sold by the pint or by the quart. Many recipes will ask you to measure those foods by the cup. Here is a helpful guide: –1 cup =1/2 pint –2 cups=1 pint –4 cups =2 pints –4 cups=1 quart –4 quarts=1 gallon

14 ©2002 Learning Zone Express14 Equivalents at the Store Answer the following questions with one of these amounts: 1/2 pint1 pint1 quart 1. A recipe for salad calls for 2 cups of cottage cheese.? 2. A recipe for a fruit dessert calls for 1 cup of whipping cream? 3. You need 4 cups of milk for a pudding? 4. You need 2 cups of sour cream to make a dip? 5. A recipe for fruit salad says to mix 8 ounces of yogurt with fruit? What size container will you buy if...

15 ©2002 Learning Zone Express15 Equivalents at the Store Now that you know how many cups make up 1/2 pint, 1 pint, and 1 quart, try to figure out how many ounces are in these amounts: –1 cup=___ oz. –1/2 pint=___ oz. –1 pint=___ oz. –1 quart=___ oz. –1 gallon=___ oz.

16 ©2002 Learning Zone Express16 Basic Equivalents Pop Quiz 1.1 pint=____ cups 2.1 gallon = ____ quarts 3.1 quart =____ cups 4.1 cup =____ tablespoons 5.1 tablespoon =____ teaspoons

17 ©2002 Learning Zone Express17 Putting Cups Together Useful amounts to know: –2/3 cup=1/3 cup + 1/3 cup –3/4 cup=1/2 cup + 1/4 cup –1/8 cup=half of 1/4 cup –1 cup=1/2 cup + 1/2 cup –1 cup=1/3 cup + 1/3 cup + 1/3 cup –1 cup=1/4 cup + 1/4 cup + 1/4 cup + 1/4 cup How would you measure these amounts? 1 1/4 cups 2/3 cup 3/4 cup

18 Temperature Conversion Fahrenheit to Celsius –Subtract 32 from the Fahrenheit number, multiply by 5, and then divide by 9. Celsius to Fahrenheit –Multiply the Celsius number by 9, divide by 5, and then add 32.

19 Let’s Do Some Problems Convert the following temperatures: – 350*F = ________________*C – 203*C = ________________*F – 125*F = ________________*C – 79*C = ________________*F

20 Recipe Conversion To calculate a recipe’s conversion factor, divide the amount of food desired by the amount of food yielded by the original recipe. Desired yield / Original Yield = Conversion Factor “Just DO it”

21 Recipe Conversion Cont. Sometimes you have to change the portion size as well. –Original recipe – 24 (number of portions) x 6 oz. (portion size) = 144 oz. This is the old yield. –Converted recipe – 56 (number of portions) x 8 oz. (portion size) = 448. This is the new yield. –Then “DO” it.

22 Let’s Do Some Problems A recipe yields 16 but you need 20. What is the conversion factor? A brownie recipe yields 12. You need 40 for a party. What is the conversion factor? If a recipe serving 100 should serve 150, what is the conversion factor? Your chicken cordon bleu recipe yields 4 6oz servings. You need 8 8oz servings. What is the conversion factor?
