Strand 6 Students will explain basic culinary math concepts and their use in standardized recipes.

Standard 1: Proper measuring techniques and tools Measurements are either by volume or by weight. *Volume measurement tools include teaspoons, tablespoons, cups, pints, quarts, gallons, and various sizes of ladles and scoops. Weight measuring tools include balance/baker scales, spring scales, and digital scales.

*Balance/Baker Scales *A scale with two balanced platforms. Ingredients to be weighed are placed on one platform and counterweights are placed on the other. Popular because of its capacity to weigh large amounts of dry ingredients. Video

*Digital Scale *A scale that weighs items digitally. Easy to tare!

*Spring Scale *A scale with a spring at one end, with a hook to attach an object at the other.

*Standardized Recipes *Standardized recipes are used in the industry and include the following: Name of the recipe Ingredients Detailed step-by-step preparation directions Portion sizes Recipe yield Pans and tools used in preparation Often nutritional information

Standard 2: Equivalents and yield Measurement equivalents review: 3 t = 1 T 1 qt = 32 oz 16 C = 1 gal 2 C = 1 pt 8 fl oz = 1 C 4 C = 1 qt 1/3 C = 5 T + 1 t 1 lb butter = 2 C 16 T = 1 C 4 qt = 1 gal 60 min = 1 hr 2 pt = 1 qt 16 oz = 1 lb

Standardized Recipe USDA definition: “A recipe that has been tried, adapted, and retried several times for use by a given foodservice operation and has been found to produce the same good results and yield every time when the exact procedures are followed with the same type of equipment and same quantity and quality of ingredients.

Recipe: Written instructions used to prepare a known quantity and consistent quality of a certain food. Components of a recipe: Title (name of the recipe) *Yield: how many servings the recipe will make List of ingredients and amounts, listed in order they appear in the recipe Step by step directions in order to be completed Equipment – container size and type Temperature and time

Benefits of Standardized Recipes Customer satisfaction: popular menu items are consistent in every detail of ingredient, quality, preparation, and presentation. Consistent nutrient content: ensure that nutritional values per serving are valid and consistent. Food cost control: consistent and accurate food cost control as same ingredients and quantities per serving are used each production.

Benefits of Standardized Recipes Efficient purchasing procedures: food quantity needed for production is calculated using standardized recipe Inventory control: predictable food quantities will be used each time recipe is used Labor cost control: written procedures promote efficiency of labor time and foodservice personnel needed for product preparation. Training costs are reduced due to specific preparation instructions on standardized recipes

Benefits of Standardized Recipes Increased employee confidence: standardized recipes decrease production problems and prevent food shortages. Reduced record keeping: the amount of information needed on a daily food production record will be reduced. The food production record can reference the recipe, servings needed, and predict leftover amounts.

Convert Recipe Yields Divide the new yield by the old yield to get the conversion factor: New yield / old yield = conversion factor Multiply every recipe ingredient by the conversion factor to get the new quantity needed for the new yield: Old ingredient quantity x conversion factor = new quantity Yields in weight or fluid ounces are more uniform to work with.

Example Original recipe makes 8 muffins. We want to make 24 muffins. 24/8 = 3 (conversion factor) Multiply each ingredient by conversion factor. ½ C butter ½ C x 3 = 1 ½ C butter 1 C sugar 1 C x 3 = 3 C sugar 1 t baking soda 1 t x 3 = 3 t baking soda 1 T baking soda

Example Original recipe makes 20 cookies. We want to make 4 cookies. 4/20 = 0.2 (conversion factor) Multiply each ingredient by conversion factor. ½ C butter ½ C x 0.2 = 0.1 C butter ?? 10 grams sugar 10g x 0.2 = 2g sugar 1 g baking soda 1 g x 0.2 = 0.2g baking soda
