Recipe Scaler
Resize one ingredient accurately when a recipe serves too many—or not enough—people.
How it works
New amount = original amount × target servings ÷ original servings.
Three practical tips
- Scale spices conservatively and adjust to taste.
- Cooking vessel size and timing may also need to change.
- Repeat the same serving ratio for every ingredient.
Can every ingredient be scaled linearly?
Most can, but seasoning, leavening and cooking time sometimes need judgement rather than a strict multiplier.
