What to watch when you make more or less
Scaling a recipe means multiplying every ingredient by the same scale factor: Scale factor = servings you need ÷ original servings. Going from 4 to 6 servings gives a factor of 1.5, so 2 eggs become 3 and ½ cup of butter becomes ¾ cup. Results are shown as kitchen fractions (¼, ⅓, ½, ¾) where that's easier to measure. What doesn't scale in a straight line: • Eggs: round to whole eggs, or beat one egg and use part of it. • Spices, salt and strong flavors: add a little less than the scaled amount and season to taste. • Baking time and temperature: keep the temperature; a bigger or deeper pan needs longer, a smaller one less. Check early. • Pan size: to double the servings, double the pan's base area, not its depth. • Yeast and baking soda: for big batches, staying slightly under the factor usually works better. To switch between cups, spoons and grams after scaling, use the kitchen converter.
Common questions about scaling recipes
Divide the servings you need by the original servings and multiply every ingredient by that number. To turn a 4-serving recipe into 6, the factor is 6 ÷ 4 = 1.5: ½ cup of butter becomes ¾ cup.
