Worked example
Use 8 oz of a subrecipe costing $0.25/oz and add $4.50 of other ingredients.
Subrecipe cost per unit: 0.25 USD / unit
Subrecipe quantity used: 8 same unit
Other ingredient line costs: 4.5 USD
- The withdrawn subrecipe costs $0.25 per oz × 8 oz = $2.
- Add $4.50 of other ingredients: $2 + $4.50 = $6.50.
Example result: $6.50
Frequently asked questions
Do I enter the entire subrecipe batch cost?
Only if the parent actually consumes the whole batch after converting it to the appropriate unit basis. Normally enter the unit cost and the amount withdrawn.
Can the parent use several subrecipes?
This form has one component withdrawal and an aggregate Other ingredient line costs field. Establish additional component costs separately without double-counting.
