Because many formulas assume the ingredients listed are ready to cook, it is necessary to consider trim loss when purchasing items. In such cases, the edible-portion quantity must be converted to the as-purchased quantity that will yield the desired formula measure.
Example

A formula requires 20 lb peeled and diced potatoes. The yield percentage for potatoes is 78 percent (0.78). Therefore, 20 lb divided by 78 percent will equal the amount to purchase. Generally, the as-purchased quantity obtained by this method is rounded up (in this example, to 26 lb), since the yield percentage is, by its nature, an estimate.
