PUTTING IT INTO PRACTICE
Ingredient Purchase Quantity: a worked example
The values below are an illustrative example, not a recommendation. Replace them with measurements or assumptions that match your question.
| Input | Example value |
|---|---|
| Required edible weight (g) | 800 |
| Edible yield (%) | 80 |
| Result | 1,000 g |
- Check the input labels and enter the example values above.
- Apply the relationship: Purchase weight = edible weight/(yield/100).
- The result is 1,000 g, rounded for display.
How to interpret your result
Assumes the yield estimate applies to the ingredient quality and preparation method.
Raw, cooked and trimmed weights are different measurement stages. An edible-yield percentage describes the remaining share after preparation. Scaling ingredient amounts does not automatically scale cooking time.
