Lines without a number are left untouched. Salt, spices, leaveners and yeast do not scale linearly — see the scaling guide for the adjustments to make by hand.

How to use it

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