Why is Math important in Culinary Arts? • Measurements • Recipe Conversion • Yields • Recipe Costing • Food Costing • Menu Costing
Rule # 1 Get over your math phobia! Calculators are our Friend!
Rule # 2 Know Standard Measurements • Volume (cups, quarts, gallons, and oz. • Weight (16 oz. = 1 lb.)
The Problem Convert 252 oz. of water into something you can measure.
The Tools • Teaspoon • Tablespoon • Shot Glass • Cup • Pint • Quart • ½ Gallon • Gallon • Ladles
Measurements Count Volume Weight
Weight, mass Very accurate Scales needed Liquid or dry Lbs, oz., grams
Scales Baker’s Scale Portion Scale Digital Scale
Volume, space Not as accurate Liquids or dry Cups, oz., Tbsp. Tsp.
Smaller than an Ounce = 3 Teaspoon 1 Tablespoon = 2 Tablespoons 1 Ounce
Count Each Large or small amounts
Cup Equal 8 ounces 16 Tablespoons 48 Teaspoons
Pint Equal 2 Cups 16 ounces 8 x 2
Quart Equal 2 pints 4 cups 32 ounces 8 x 4
Gallon Equal 4 quarts 8 pints 16 cups 128 ounces 8 x 16
Liquid Measurements Gallon 4 qts...., 8 pints, 16 cups, 128 oz. ½ Gallon 2 qts..., 4 pints, 8 cups, 64 oz. Quart 2 pints, 4 cups, 32 oz Pint 2 cups 16 oz Cup 8 oz One Ounce 1 Tablespoon 3 Teaspoon

Conversion of Volume Measurements • Convert 7 cups 5 oz. into ounces. • Method • ( 7 x 8 ) + 5 = 61 oz. • Convert 24 Tbsp. into ounces • Method 1 • 24 / 2 = 12 oz. • Method 2 • 24 x .5 = 12 oz.
Converting Portion Size Example Original Recipe Yield is 10 portion at 12 oz. Desired Recipe Yield is for 32 portion at 10 oz. Convert recipe to like units (oz.) • 10 x 12 = 120 oz (old) • 32 x 10 = 320 oz (new) 320 / 120 = 2.66
Recipe Conversion Conversion Factor Old Yield (Original) New Desired Yield New recipe makes 4 gallons of soup Original recipe made 2 gallons of soup
Yields 150 guest 9 oz. Cooked Prime Rib How much do you cook?
Yields One Prime Rib = 20 lb. 4 oz. AP After trimming and cooking = 11 lb. 2 oz. EP Step 1 Convert to oz. 20 x 16 = 320 + 4 = 324 11 x 16 = 176 + 2 = 178
Yields AP Started with .549 rd to .55 324 178 EP Ended with
Use this formula: EP / Yield Factor = AP 150 x 9oz. = 1350 oz. of EP 2455 oz. AP (rd) .55 1350 Yield Factor
The Real Answer 153 lbs 7 oz This is how much you need to Fire Number of oz. in lb. 16 2455 oz. AP
