Scale factor = desired servings ÷ recipe servings. Scaled amount = ingredient × scale factor. Per portion = scaled amount ÷ desired servings.

- Round liquid ingredients sensibly — batch cooking tolerates small variation.
When it's useful

Common examples
Frequently asked
Should I scale spices the same way?
Usually no — spices, salt, and leaveners often need a gentler bump. Scale by 0.75–0.9× of the math, then taste.
Does cooking time scale linearly?
Not exactly. Larger batches usually need slightly longer cook time, not proportionally longer.
Will pan or pot size still work?
Check capacity before doubling. A pan that's full will overflow or steam instead of brown.
What's the difference between this and Recipe Scaler?
Recipe Scaler gives scaled ingredient amounts. This adds 'per portion' for meal-prep planning.
