How to use it
- Paste the ingredient list exactly as written in your recipe.
- Enter the servings the original makes, then the servings you need.
- Read the converted list — or use Halve, Double and Triple for the common cases.
- Adjust seasoning and raising agents by hand: roughly 1.5× when doubling, 0.6× when halving.
