|Occupational Area: Culinary Arts |
|CTE Concept(s): Recipe Scaling |
|Math Concepts: Ratios, Proportions, Rate |
|Lesson Objective: |How to scale a recipe to a different number of portions |
|Supplies Needed: |Handouts, white board and markers, Powerpoint presentation |
|The "7 Elements" |Teacher Notes |
| |(and answer key) |
|Introduce the CTE lesson. |Handout worksheets. |
|It is common in the kitchen to scale recipes to meet the needs of parties |Start PowerPoint Presentation |
|of different sizes, and in doing maintaining the correct proportions of |Show picture of catering event, then picture of failed cake. |
|the ingredients so that the recipe will come out with the same physical |Talk about the importance of maintain the proportions of the |
|properties and flavor profiles as the original recipe. The concepts of |ingredients or else . . . |
|Ratios and Proportions will be used to maintain original recipe profile |The use of Ratios & Proportions will be needed |
|Assess students’ math awareness as it relates to the CTE lesson. |Ask students how many: |
|Review with the students of the learning of: |Ounces in a pound, Tablespoons per cup, cups in a quart |
|Measuring units. |Convert the following to fractions: |
|Conversion of unit to largest applicable unit. |0.25, 0.125, 0.375 (= ½ 1/8 3/8) |
|Conversion from a fraction to decimal and decimal to fraction. |Convert the following fractions to decimals: |
|Vocabulary of Rates, Ratios & Proportions |3/4 , 5/8, ½ (0.75, 0.625, 0.5) |
| |Rate- compares two quantities of different units by division. |
| |Ratio – compares two quantities of the same unit by division. |
| |A Proportion occurs when two rates or ratios are equal. |
| |Have some students give some examples of ratios, or proportions |
|3. Work through the math example embedded in the CTE lesson. |If you are “doubling” a recipe how would you adjust these |
|Rate- compares two quantities of different units by division. |ingredients, or halving, how would like look on paper? |
|Ratio – compares two quantities of the same unit by division. |Ratio - 20 portions to 5 portions gives a ratio of 20:5 = 4 |
|A Proportion occurs when two rates or ratios are equal. |Conversion Factor – the “4” from the above example is a conversion |
|A conversion Factor is a ratio that is applied to multiply ingredient |factor that is now multiplied by each ingredient in order to maintain|
|recipes as the proportion of each ingredient will be the same for each. |the same proportion between the new and the old recipes |
|5. Work through traditional math examples. |Example 1: Original Recipe has a yield of 6 ptns., the new recipe |
|Example 1: Explain Ratios and Cross Product Property to arrive at Ratio |needs to have a yield of 25 ptns. One ingredient in the recipe is: |
| |Flour 1 ½ oz: |
| |[pic] = [pic] |
| |Then use the Cross Product Property: |
| |[pic]= [pic] , then ad = bc |
| |then: [pic] = [pic] -> : [pic] = [pic] |
| |6x = (25 ∙ 1 ½) |
| |6x = 37.5 oz |
| |x = 6.25 or 6 ¼ oz |
|4. Work through related, contextual math-in-CTE examples. |Example 2: Original Recipe has a yield of 4 ptns., the new recipe |
|Example 2: Introduce Ratio and relation to Conversion Factor as a labor |needs to have a yield of 18 ptns. Then find the Conversion Factor: |
|saving shortcut to the concept learned in the first Example. |[pic] Conversion Factor = [pic] = [pic] = 4.5 |
| |Now multiply each of the ingredients in the recipe by the Conversion |
| |Factor (4.5): |
| |Old recipe: Water 2 ¾ cups |
| |2 ¾ (2.75) cups ∙ 4.5 = 12.375 cups = 12 3/8 New recipe: Water 12 3/8|
| |cups or ≈ 3 Qts. + 3/8 cup |
|Answers to example in PowerPoint: |
|Ingredients: Old Qty: CF: New Qty: |
|Flour 2 cups x 2.5 = 5 cups |
|Water 8 floz. x 2.5 = 20 floz. ->1 pt. + 1/2 cup |
|Egg 4 each x 2.5 = 10 each |
|Baking Powder 1 tsp. x 2.5 = 2 ½ tsp. |
|Cinnamon 2 tsp. x 2.5 = 5 tsp. -> 1 Tbs. + 2 tsp. |
|6. Students demonstrate their understanding. |
|Now the student can do the exercises on the handouts, look at them at home, hand them in tomorrow, any questions can be address via e-mail or in|
|class in tomorrow. |
|Recipe Scaling Exercise |
|7. Formal assessment. |
|There will be a quiz on this subject at the end of the week, ensure you talk to me before then if you have any questions or need any |
|clarifications. Also, we have several catering jobs coming up where recipes will need to be scaled and your skills can be demonstrated. |
