The method
- Record the stated serving count and original quantities. Distinguish mass, volume and piece count; an amount “to taste” remains a judgement rather than a precise measure.
- Calculate the factor: desired servings divided by original servings. Multiply measured quantities by that factor without converting volume to mass unless you have ingredient-specific information.
- Review units and rounding in the new list. For part of a piece, choose a suitable measuring method; do not automatically change cooking temperature, time or technique.
Fictional worked example
A fictional recipe for 4 servings lists 200 g of an ingredient and 100 mL of liquid. For 6 servings, the factor is 1.5: record 300 g and 150 mL. One piece becomes 1.5 pieces, requiring a measurement decision rather than hidden rounding.
The record to keep
Keep the original recipe, factor and adjusted list with units. Clearly mark rounding and unquantified instructions.
Your record, step by step
For your own situation, record the following information. Check a field when it is documented; missing information still needs verification. The boxes are a reminder within this page.

Completed fictional example: these values only explain the method. Adapt the rows to your circumstances and keep unknowns explicit.
| Element | Value or observation | Interpretation |
|---|---|---|
| Servings | 4 → 6 | Factor: 6 ÷ 4 = 1.5 |
| Flour | 200 g → 300 g | Multiply quantity by 1.5 |
| Liquid | 120 ml → 180 ml | Keep ml; cooking time is not calculated here |
What this method can establish
Proportion changes quantities; it validates neither a substitution, storage method, diet nor new cooking procedure. The culinary result may need specific adjustment.
