How it works
Scale factor = desired servings ÷ original servings. Scaled amount = original amount × scale factor. For the sample: 6 ÷ 4 = 1.5, and 2 cups × 1.5 = 3 cups. Cooking times and pan sizes do not scale perfectly with amounts — check doneness, don't just multiply the timer.
Frequently asked questions
Do baking times scale too?
Not directly. A doubled cake in a bigger pan takes longer, but not twice as long. Watch the recipe's doneness cues.
What about spices and salt?
Scale them too, then taste and adjust — strong flavours don't always feel right at an exact multiple.
