Scale ingredients by the ratio of new servings to original servings; bake time changes far less than quantity does.
New amount = original × (new servings ÷ old servings)

Frequently asked questions
Do I scale spices linearly?
No. Salt, chilli and strong spices should be scaled to about 75% of the linear amount, then adjusted to taste.
Does baking time double?
No. Heat penetration depends on depth, not total volume, so use pan size guidance and test for doneness.
