Frequently asked questions
How do I scale a recipe up or down?
Divide the desired servings by the original servings to get a factor, then multiply every ingredient by it.
Does every ingredient scale evenly?
Most do, but salt, spices, and leaveners (baking soda/powder) often need adjusting by taste and observation rather than straight multiplication.
Can I scale baking recipes?
Within reason. Large jumps change pan sizes and bake times, so scale in modest steps and watch closely near the end.
How do I halve a recipe?
Enter half the servings, or use a scale factor of 0.5. Awkward amounts like half an egg can be whisked and measured.
Do cooking times change when I scale a recipe?
Total time can, because larger batches, deeper pans, or more pieces heat differently. Judge by doneness cues, not just the original time.
How do I convert a recipe to a different number of servings?
Enter the original and desired servings above to get the scale factor, then apply it to each ingredient amount.
