Course Information on Blackboard Syllabus 4 Assignments Supplementary materials passed out in class: A recipe to standardize for assignment #1 A chart to complete for assignment #3

On to the lecture!: 

On to the lecture!

Standardized Recipes: 

Standardized Recipes (also called a FORMULA) A set of instruction describing the way a particular establishment prepares a particular dish. WHY? Controls costs Controls yields (quantities) Controls quality and consistency

Recipe Standardization in Foodservice: 

Recipe Standardization in Foodservice Repeat customers want to enjoy the samae food they like previously Important in any foodservice institution, but ESSENTIAL in the chain operation* * QSR were pioneers in producing standardized food products

Standardized Recipes are Key: 

Standardized Recipes are Key Keep quality standard Keep flavor standard Enables new employees to maintain the establishment’s reputation Just about anyone can prepare the recipe Aid in portion control  cost control

If you can’t measure it, you can’t manage it.: 

If you can’t measure it, you can’t manage it.

Issues to Consider…: 

Issues to Consider… Make all measurements by weight Do not abbreviate Have steps in the proper order Ingredients to be mixed together should be listed together List procedures nest to ingredients that are involved in the procedure List the item first and the form second

More Issues to Consider…: 

More Issues to Consider… Use terminology the workers will understand Be specific about seasonings. Never use a phrase like “season to taste” Outline a specific test to tell when a product has been completed List source of original recipe Provide for portion yield increments to avoid on-the-job calculations

Slide19: 

Bakers talk about FORMULAS, not recipes In a professional baker’s formula, ingredients are WEIGHED, not measured The bakeshop is similar to a chemistry laboratory in the scientific accuracy of the procedures and the complex reactions that take place during baking

Slide20: 

The following ingredients may be measured because they weigh one pound per pint: Water Milk Eggs Spices and other flavoring ingredients (vanilla) may be measured because they are used in such small quantities

Four Methods of Formula Presentation: 

Four Methods of Formula Presentation

Converting Recipes: 

Converting Recipes Factor Method – a conversion factor is determined and multiplied by each ingredient in the recipe Percentage Method – determine the percentage of each ingredient in a recipe. This percentage remains constant for all adjustments. Merely multiply the total yield desired by the percentage of each ingredient.

Factor Method: 

Factor Method Obtain a conversion factor: Desired Yield (# portions) Current Yield (# portions)

Changing Portion Size AND Yield: 

Changing Portion Size AND Yield New # portions * New portion size Old # portions * Old portion size

Let’s convert a recipe…: 

Let’s convert a recipe…

First, look at the serving size: 

First, look at the serving size Often home recipes have serving sizes that are too large for institutional serving sizes. What is the typical meat serving size recommended? Is that the serving size of this recipe?

Find the Factor: 

Find the Factor New # portions * new portion size Old # portions * old portion size 48 portions * 4 ounces 6 portions * 8 ounces 192/48 = 4

IMPORTANT NOTES: 

IMPORTANT NOTES Quantities should be stated in appropriate measures: NOT 12 Tablespoons BUT ¾ cup Rounding is also an issue and can be critical in baked goods

Pounds and Decimals: 

Pounds and Decimals Can you weigh out 1.83 pounds for me?

Weights and Measures: 

Weights and Measures Liquid ingredients are measured in volumetric equipment

Weights and Measures: 

Weights and Measures Dry ingredients are weighed for accuracy

Weights and Measures: 

Weights and Measures Measuring spoons and cups are not used as frequently in quantity food production as they are at home. Seasonings are the most common use of these.

Converting Recipes: 

Converting Recipes When converting a home recipe to a commercially-viable one, many ingredients must be converted from volumetric to weight. Food for Fifty – Table 1.3 (pp 22-31) “Food weights and approximate equivalents to measure”

Example: 

Example Your home recipe called for one cup of diced potatoes. Your factor is 8 which increases your need to 8 cups of potatoes. This is not the correct unit to put in your recipe, it needs to be in pounds and ounces. Look up weight equivalent in FFF

The Ounce Quandry: 

The Ounce Quandry

Some equivalents you MUST know!: 

Some equivalents you MUST know! 1 Tablespoon = ½ fl oz 3 teaspoons = 1 Tablespoon 16 Tablespoons = 1 cup 8 fl oz = 1 cup 2 cups = 1 pint (16 fl oz) 2 pints = 1 quart (32 fl oz) 4 quarts = 1 gallon (128 fl oz) DRY WEIGHT: 16 oz = 1 pound

A question to ponder…: 

A question to ponder… Does a cup of feathers weigh as much as a cup of lead?
