Formula Percent A formula percent is the percentage of an ingredient in the total formula. To calculate a formula percent, every ingredient’s amount is converted to a common measurement. The measurements are added to give a total batch size. Each ingredient amount is divided by the batch size to determine a percentage for that ingredient. The total of a formula percentage will always be 100%. Usually formula percent is determined using weights, but any measurement can be used as long as that measurement is consistently used. You cannot determine formula percent based on volumes then use those percentages on weights (or vice versa). In this case, if we used teaspoons (1 cup = 48 teaspoons), the results would be (batch size = 145 teaspoons):
If we used weights, the results would be (batch size = 471 grams):
Using a formula percent to scale recipes is similar to the basic method. The scale factor is multiplied times the original batch size to determine the new batch size. The new amount of an ingredient is determined by multiplying the ingredient’s formula percent times the new batch size. In the volumes example, the original batch size is 145 teaspoons (96 + 48 + 1). Doubling the recipe gives us a scale factor of 2. The new batch size would be 290 teaspoons (145 * 2). The new ingredient amounts would be:
192 teaspoons equals 4 cups (192/48) of masa. Water is 2 cups (96/48) and salt is 2 teaspoons. For weights, the amounts would be (new batch size = 471g * 2 = 942g):
456 grams of masa = 4 cups (456/114). 474 grams of water = 2 cups (474/237) and salt = 12 grams.
