Multiply every ingredient in the recipe by the scale factor.
What this means
Scaling a recipe is simple multiplication: divide the number of servings you want by the original number to get a factor, then multiply every ingredient by it. Doubling a 4-serving recipe to 8 servings is a 2× factor. The same factor applies to every ingredient, though for spices and seasonings it's often wise to scale slightly less — taste as you go.
Recommendations
- Scale the 'workhorse' ingredients (flour, liquid, meat) exactly; seasonings can be nudged to taste.
- For very large or very small batches, timing changes — small batches cook faster, big ones slower.
- Eggs scale awkwardly: scale to whole eggs where possible.
Watch out
- Scaling ratios that are non-linear (yeast, baking powder, salt in bread) can behave differently — extreme scaling isn't always a straight multiply.
- Pan size and cooking time don't scale with servings.
